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
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.
