Concentration / Display / Ensemble / Statistics

Summary: This procedure is intended to analyze the binary output files from any of the ensemble simulations. The output file naming convention is such that they are defined by the concentration output file name set in the CONTROL file to which is automatically appended a three digit sequential number suffix (.000). The ensemble simulation needs to be for a case in which experimental data are available for verification. The script converts the output to the DATEM format, and then calls the statistical analysis program which appends a statistical summary for each member to a single output file.

Step 1: defines the DATEM formatted measured data file and unit conversion factor required to convert the HYSPLIT concentration predictions to the same units as given in the measured data file.

Step 2: defines name of the statistical output file that will contain the statistical results for each ensemble member compared with the measured data values. Normally the statmain program outputs one results file per execution. In this configuration, a subset of the the complete results for each member are appended to a single file. The complete statistics are available in file named stat_000.txt.

Step 3: runs sequentially through all steps, processing each ensemble member using c2datem to convert that binary concentration data to the DATEM format, and then running statmain to append the results to the statistical output file.

Default file names: The following describes the assigned default input and output files names for each processing section, so that they can be identified in the working directory. File names in italics are the ones that can be changed through the menu.
