HYSPLIT Model Updates
Highlights of Recent Updates
February 08 Revision (4.8)
- new concentration grid plot color fill program and added to GUI
- revised conprob files (and GUI) to be consistent with box plots
- new GUI for box plots for ensemble simulation results
- UNIX testing script for version control
- emitimes permits multiple species on one particle when maxdim>1
- improved puff split-merge algorithm and added new namelist options
- removed FTP of NCEP GRIB-1 files from GUI menus
- added additional download options for HYSPLIT compatible data files
November 07 Revision (4.8)
- Plotting routines were modified in terms of centering, colors, and clipping
- Units were changed in the source-attribution code for consistency
- The internal vertical grid structure was corrected for high resolution input data
- Emissions were corrected to handle releases shorter than the model's time step
- The termination message shows if points fall outside the domain in terms of space or time
- Additional puff split-merge factors were moved from the constants to the namelist input
- A multi-trajectory geo-location option based upon measurment data was added to the GUI menu
- Cluster number labels were added to the trajectory plotting program
- A new GUI tab can be used to install model updates when they become available
August 2007 Revision (4.8)
- Mixed layer depth computed from minimum temperature
- Default short-range turbulence from profiles rather than fluxes
- Terrain correction for starting heights above mean sea level
- Automated source attribution configuration from measured data
- Integrated solution of the source-receptor matrix
- Modified meteorological data input algorithm for sfc obs
March 2007 Revision (4.8)
- Options to set the day/night anisotropy when using TKE fields
- Automatic selection of the most recent forecast data file
- New options to compute maximum and maximum average concentrations
- Updated namelist configuration menus with more information
- New map projections and latitude-longitude labeling options
- More flexible data FTP with server selection and progress widget
