The following is a brief description of the HYSPLIT updates and new features added since the last release. Note that only a few sections are affected by the update and older HYSPLIT versions will still work and give the same results, for the most part, with the contents of this tutorial.

Meteorology

  • Add api2arl_v6 converter that reads scaledValueOfFirstFixedSurface for pressure levels.
  • Updates to api2arl_v5 converter.
  • Increase number of vertical levels to 99.
  • ARW2ARL -b option can take up to 4 digits.

Trajectories

  • Placeholder

Air Concentrations

  • Add Freitas plume rise scheme.
  • Adjust wind error flag by checking IDSP and ZICONTROLTF.
  • Updates to PARTICLE.DAT and PARTICLE_STILT.DAT formats.

Special Simulations

  • CONPROB works with concentration grids of different sizes, provided grid spacings remain the same across concentration grids.

Display Options

  • Expand the CONCPLOT -c option to take the number of contours.
  • Add -c60 and -61 options to CONCPLOT that use interval of sqrt(10).
  • Add +8 option to CONCPLOT for specifying near-min contour level.
  • Update HYSPLITPLOT to version 0.9.1.
  • Replace STAMEN_TERRAIN and STAMEN_TONER map backgrounds with OPEN_STREET and OPEN_TOPO, respectively.
  • Display message when no plume is drawn.
  • Updates to XML generation for KML XSD compliance.
  • Bug fix with plotting vertical projection trajectories.
  • Bug fix with creating KML when initial plot frames are empty.
  • Bug fix with creating KML for concentration-to-station via GUI.

Internal

  • Arrays are allocated with zero initial values.
  • CONPROB prints error message when no input files are present.
  • Add -d option to CONAVGPD.
  • Bug fix with updating internal vertical coordinate after advection.
  • Bug fix with updating time averaging wind for backward runs.
  • Bug fix with initializing variables for Grell convection.
  • Bug fix with extracting station via graphical user interface.
  • Bug fix with setting lat lon domains for DATA_DEL.
  • Bug fix with clustering trajectories via graphical user interface.
