Program to read multiple HYSPLIT concentration files and a DATEM
formatted measured data file to create a merged CSV formatted
coefficient matrix that can be used as input to a linear equation
solver. The HYSPLIT files can be forward calculations from a
source point, one file per release time, or backward calculations
from multiple receptor points. The output matrix will consist of
columns each release time and one row for each measurement placed
in the last column. The HYSPLIT concentration binary input file
names are identified in an input file of file names. The program
determines the direction of the calculation (forward/backward)
based upon the time difference between successive concentration
outputs. The backward calculation is assumed to correspond to a
measured value and requires the command line entry of a source
position (-s) where the model calculations will be extracted. The
half-life entry is used to decay correct the measurement data back
to the simulation start time. |

Usage: con2dose [input file] [output file] |
|
Temporally averages the input binary concentration file (output from HYSPLIT), converts
to dose units and outputs a new binary dose file. The calculation applies only for
long-term doses and requires the con2dose.dat file which contains various dose
conversion factors (EDE, bone, lung, thyroid, TEDE, etc.) for each radionuclide. The
con2dose.dat file is only provided with the source code distribution.
Requires each pollutant ID in the HYSPLIT output file to have a matching radiological
species ID in the con2dose.dat file. This approach has been replaced by the
more general Transfer Coefficient Matrix (TCM) where surrogate species are used in
the HYSPLIT calculation and where decay is also applied in the post-processing step. |

|
Converts a HYSPLIT binary concentration/deposition file to dose in rem/hr. The
HYSPLIT calculation should be done using a unit emission so that the concentration
units are m-3 and the deposition units are m-2. This program reads the file
activity.txt which contains the activity (Bq) at time=0 for all the isotope products.
The -acreate switch will create a sample activity.txt file for a 1KT device, while
the -afdnpp switch creates a sample file where the activity equals the maximum 3h
emissions from the FDNPP accident. During the processing step, the cumulative
product of the activity and dose factor is computed for each decay weighted
concentration averaging period independently for noble gases and particles. For
general applications, HYSPLIT should be configured for two species: NGAS and RNUC.
For most radiological dose applications, this method is preferred over the original
approach using con2dose because decay is treated in the post-processing step
and multiple radionuclides can be assigned to a single computational species. This
approach works best when emissions are constant. For time-varying emissions, use
the program condecay before running con2rem.

Converts binary concentration file to a latitude-longitude based ASCII file, one
record per grid point, for any grid point not zero. Adheres to the
informal source-receptor-sensitivy (SRS) output format that seems to be in
use with FLEXPART people for storing concentrations, backwards sensitivities,
and even depositions. This program forces a simple output - a single species
at a single level. It is up to other programs to combine SRS files into
something more complex, if and when desired. See con2ctbt for the
original version of this program.

|
Processes a series of binary unit-source concentration files, which
consists of a file name starting with TG_{YYYYMMDDHH} that identifies
the associated release time. The program command line contains one
entry for each species to be multiplied by a source term and decayed
by its half-life to the end of the sample collection period. Not all
species in the input file need to be converted. The resulting output
file name is called DG_{YYYYMMDDHH}. Emission values are defined in the
input file named cfactors.txt. All concentration input files must be
identical in terms of species and grid resolution.
This program would be used in conjunction TCM processing applications. In the
situation where the emission rate is constant with time, the program con2rem
can be used to apply emissions, decay, and convert to dose. However, when emissions
are time-varying, then the concentration file for every release period (TG files)
would be processed by condecay for the emissions and decay, and then by
con2rem for the final conversion to dose.

The code will solve for values of the source emission rate vector to satisfy the
measured values using a cost function approach to minimize the difference between
the observations and model predictions by varying the source term from a first-guess
estimate. The model predictions file should be in CSV format with the last column
corresponding to the measurements. The first row is the time associated with each
unknown source. The CSV file could be created using the program C2ARRAY.
All solution configuration values are set in the PARAMETER_IN file. See the
program's README file for more information.

Program reads the output file of the cost function (lbfgsb) analysis and converts
the time field from EXCEL fractional days format to year, month, day, hour, value,
where value is the emission rate. The output is in the free-form cfactors
format of time-varying emissions in much simpler format the EMITIMES. This
file is normally referred to as cfactors.txt and it is used by programs
tcmsum and concdecay.

|
The matrix program is used to extract source or receptor information from the
HYSPLIT generated source-receptor matrix. Two output modes are available. In
receptor mode a receptor location is specified and the program computes the
contribution of each source to the selected receptor point. In source mode
a source location is specified and the program outputs the concentrations at
all the receptor locations. All output files are in standard HYSPLIT binary.

The code will compute the inverse of the coefficient matrix (CM) and solve for values
of the source emission rate vector to satisfy the measured values. The default approach
is to use Singular Value Decomposition on the CM, which is defined by M equations
(receptors) and N unknowns (sources). The input file should be in CSV format with the
last column corresponding to the measurements. The first row is the time associated
with each unknown source. The CSV file could be created using the program C2ARRAY which
processes the HYSPLIT binary coefficients and DATEM formatted measurement data files.
The percent delete is the percentage of the lowest TCM values to be deleted.

the mean value at each grid point, which is then written to the output file
cmean. Note individual time headers are not checked and the output
time fields are the same as the last input file.
This program provides a quick way to generate an ensemble mean rather than
using conprob which generates all the probability files including
the mean.

|
Program to add together two gridded HYSPLIT concentration files, where the
input file is added into the base file and written as a new file. The input
and base file need not be identical in time, but they must have the same
number of pollutants and levels. The file contents are matched by index
number and not height or species. The horizontal grids need to be identical
or even multiples of each other and they also need to intersect at the
corner point. Summations will occur regardless of any grid mismatches.
Options are also available to select the maximum value or define the input
file as a zero-mask such that grid points with non-zero values become zero
at those locations in the base file when written to the output file. The
intersect option only adds the input file to the base file when both
have values greater than zero at the intersection point, otherwise the
value is set to zero. The replace option will replace the value from the
base file with the value from the input file. This option is normally used
in conjunction with a non-zero radius. The -t flag forces the time labels
for each sampling period to represent the minimum starting time and maximum
stop time between the two input files. |

|
Program to combine two gridded HYSPLIT concentration files; one a fine
grid and one a coarse grid. The coarse grid is recalculated on a grid
covering the same area except that the grid has the resolution of the
fine grid provided. The file contents are matched by index number but
not height or species. You must make sure that the fine grid spacing and
span are even multiples of the coarse grid spacing and span. The coarse
grid points must be also be points on the fine grid. Summations will
occur regardless of any grid mismatches. Prior to writing the coarse grid
values into to the final large fine grid, the new fine grid values are
given a 1/r2 weighting using the surrounding coarse grid values.

|
The program reads two HYSPLIT concentration files and applies the
second file as a mask to the first. Any non-zero values in file
#2 becomes zero in file #1. For example, in source attribution
calculations, the second file can be used to eliminate grid cells
that do not contain the source because the backward calculation was

window for all time windows that fall between the window start
and stop times.
|
|
|
|
USAGE: conmaxv [options] -i[input file name (cdump)] -o[output file name (cavrg)] -s[sliding time window in minutes (-1, defaults to data interval)] |
|
Computes the maximum value at each grid cell using a sliding time window. The sliding
time interval must be evenly divisible by the averaging (data interval) time. The output
represents a single time period, the maximum value over the entire time period. For example,
for a one hour simulation, with output every 5 minutes, there would be 12 time periods in
the HYSPLIT concentration output file. If the sliding time window is set to 15 minutes, at
each grid point, the program computes 12 average concentrations, for time periods 1,2,3 and
then 2,3,4, and so on. A single maximum value of those 12 sliding window averages is written
to the output file at that grid point. Maximum concentrations are used primarily in hazardous
chemical exposure calculations.

Generates multiple lat-lon source points from a control file in which the
first lat lon points are considered to be the corner point. Each source point
represents a forest fire smoke emission point based upon satellite analysis.
The program is intended to be run in two modes. If no BlueSky emission data are available (BLUESKY.TXT does not exist), then a default emission scenario is assumed for each pixel location in FIRES.TXT. This pass will create the BlueSky burns input file (BLUESKY.CSV). This file must then be processed in the BlueSky framework to produce the specied emission file for that location. On the second pass to this program, the BLUESKY.TXT file is read to create a modified CONTROL file with emission locations, rates, and burn areas. The script calling this program should delete all BLUESKY.??? files prior to the first pass execution. | ||||||||||||||||

The program converts model output data in GRIB2 format using the
ECMWF ecCodes library (formerly used the ECMWF grib_api library) to
the ARL packed format required for input to HYSPLIT. The data must
be a global latitude-longitude or regional Lambert grid defined on
pressure surfaces. The program will only convert one time period
in any one input file. Multiple time period output files can be
created by appending each time period processed using the cat command. v1 : Pressure level data from the NCEP NOMADS server v2 : Hybrid sigma coordinate; index increases with Z v3 : NOAA pressure and ECMWF hybrid ½o data; index decreases with Z v4 : GSD HRRR data on pressure level surfaces |

Advanced Research WRF to ARL format converts ARW NetCDF files to a
HYSPLIT compatible format. The WRFDATA.CFG namelist file can be manually
edited to select other variables to output. X variables are not found in
the WRF output but are created by this program. All variables require a
units conversion factor be defined in the namelist file. When the input
file contains data for a single time period, then the ARL format output
file from each execution should be appended (cat >>) to the output file
from the previous time periods execution. |

Creates a gridded meteorological file for multiple time periods in ARL packed
format from an ASCII input file of surface observations. For example: YY MM DD HH MM MSLP SFCP T02M RH2M MIXD WDIR WSPD PASQ SHGT 07 09 04 11 00 1007 0937 0021 0079 552.0 270 5.0 4 00175 07 09 04 12 00 1008 0938 0022 0065 745.0 300 6.0 4 00175 The output data grid is compiled for 25 by 25 grid points at 10 km resolution and it is centered about the command line lat-lon position. This program is very similar to stn2arl except the input file contains the additional variables, SFCP, T02M, RH2M, SHGT, and the vertical coordinate of the output grid is sigma rather than absolute pressure units. |
|

Usage: add_data [station data file name] [ARL gridded file name] ... followed by the optional parameters {none= (default)}: -d to turn on diagnostic output -g{#}, where # is the grid point scan radius (9999) -t{#}, where # is (1) for blending temperature or 0 for no blend -z{#}, vertical interpolation: (0)=PBL, 1=all, 2=above PBL |
|
Edits the packed meteo data file based upon selected observations
in the station data input file. The station file contains wind
direction and speed at times, locations, and heights (any order).
Observations are matched with the gridded data interpolated to
the same location. Gridded winds are then adjusted in direction
and speed to match the observation. Those winds are then inter-
polated (using 1/r^2) back into the gridded data domain in the
mixed layer. The program is not intended to be a replacement for
data assimilation but a quick way to adjust the initial transport
direction to match local observations near the computational
starting point. The optional -g# parameter is used to limit the
radius of influence of the 1/r^2 weighting to # grid points in a
radial direction from each of the observation locations. The
default (9999) is to use the whole grid. Vertical interpolation
defaults to mixed layer only, but can be set to do the entire
profile, or it can just process the levels above the mixed layer.

Usage: add_grid prompted standard input: line 1 - /meteorological/data/directory/ line 2 - ARLformat_datafile_name Output: addgrid.bin |
|
Program to interpolate an existing meteorological data file
to a finer spatial resolution grid at integer intervals of
the original grid spacing. The program should be run before
add_data to insure that the
resolution of the meteorological data file is similar to that
of the observations. This combination of programs was used to
merge WRF and DCNet data for dispersion model calculations.

|
|
|
Usage: add_miss prompted standard input: line 1 - /meteorological/data/directory/ line 2 - ARLformat_datafile_name Output: addmiss.bin |
|
Examines a file for whole missing time periods (records missing)
and creates a new output file with interpolated data inserted into
the proper locations. The first two time periods in the file cannot
be missing. The missing data records must already exist in the file
to use this program. Files with DIFF records will
not be interpolated correctly.
|
|
|
|
Usage: add_time prompted standard input: line 1 - /meteorological/data/directory/ line 2 - ARLformat_datafile_name line 3 - The output frequency in minutes Output: addtime.bin |
|
Program to interpolate additional time periods into a meteorological
data file. The new data output interval should be an even time multiple
of the existing data file. Options are set through standard input.
Linear interpolation is used to create the data for the output time periods
that fall between the time periods of the input data file.
Files with DIFF records will not be interpolated correctly.

|
Extracts a subgrid from a larger domain file and adds additional
3D records for the velocity variances: u^2, v^2, and w^2. These are
computed from the TKE field. The program requires the input
meteorological file to contain the turbulent kinetic energy field.
The output file may then used as an input file for other programs
that will add observational data.
The program can be used to create a meteorological data file with
velocity variances over a smaller domain where observational
variance data (i.e. DCNet) can be assimilated using add_data.

|
|
Usage: arl2meds prompted standard input: line 1 - /meteorological/data/directory/ line 2 - ARLformat_datafile_name Output: meds.fix |
|
Converts one ARL SHGT (terrain height) data record to MEDS format. This file
may be required by the meds2arl converter if the surface terrain (ST) variable
is not included within the MEDS data file. Note that the data may need to be
realigned with either the prime meridian or dateline to match the alignment
of the MEDS data. The MEDS data alignment is written to the meds.txt
diagnostic message output file by the meds2arl program. Therefore it may take
one or two iterations of arl2meds and meds2arl to get the proper command line
input parameters. |
|
This program is an orphaned application as the primary converter program
meds2arl has been moved to the ~/data2arl/legacy directory. |

|
|
|
Usage: edit_flux prompted standard input: line 1 - /meteorological/data/directory/ line 2 - ARLformat_datafile_name line 3 - the new roughness length (m) Output: editflux.bin |
|
Edits the all flux fields based upon a pre-determined roughness length.
Using U = U* k / ln(Z/Zo) with the original Zo and a new equation with
a modified Zo^ that represents the new larger roughness length, take the
ratio of the two equations such that U*^/U* = ln(Z/Zo)/ln(Z/Zo^). For
computational purposes, assume that Z is always one meter greater than Zo^.
Then the the momentum flux fields are multiplied by this ratio, while T* is
divided by the ratio.

|
Program edit_miss is used to interpolate missing variables
in an existing meteorological data file from adjacent time periods.
The missing data must already exist in the file as valid records
with either a blank or missing code in the field. For files with
missing records, use program add_miss. Files
with DIFF records will not be interpolated correctly.
|

Usage: edit_null prompted standard input: line 1 - Data grid size (nxp, nyp) for all files line 2 - Data set name (with NULL field ID) line 3 - Output data set name with merged data line 4 - Data set name with the one-field to replace NULL |
|
This program replaces one record per time period in a file where the
missing record is identified by NULL. The new field is read from another
file than only contains the one variable. The records are matched by time.
For example, the program can be used to insert precipitation records into
a file. Some editing and recompilation may be required.

Converts the particle dump output file (big-endian binary) to an ASCII-formatted particle
file, and as an option, output an inventory file listing the date/time(s) of the output.
Each output time of the ASCII-formatted particle file is compose of a header record
indicating the number of particles to follow for that time period. With the optional -a1
text file option, PAR_GIS.txt is created, where each particle has one line, and the
following is written: header record + one record for each particle.

|
The program provides for the spatial adjustment of the particle positions in the HYSPLIT
binary particle position output file as specified on the command line. One or more files
may be processed by a single execution with the adjusted output always written to a new
file name. The position adjustment is only applied to one time period if the input file
contains multiple time periods. The shift is specified in either delta latitude-longitude
units. Unless a latitude-longitude window is specified, all particle positions in the fil
are adjusted. Adjustments outside of the window may be linearly blended to zero adjustment
at a distance of two windows. Adjustments may also be specified as a rotation and distance
from a point. Particles in a window may also be deleted. |

Program starts with N trajectories (clusters) and ends with one cluster. MC is
the current number of clusters. Program clusend identifies stop point.
Cluster pairs are chosen based on total spatial variance (TSV - the sum of
the within-group sum of squares). The two clusters to be paired result in the
minimum increase in TSV. |
