Smoke Forecasting Model Change Log

07/25/2013 - All smoke runs using HYSPLIT on new supercomputer (WCOSS). Two notable fixes:
- relaxed plume rise restriction
- removed error of short-duration fires carried into the next day
02/24/2010 - Hawaii smoke forecast became operational.
09/29/2009 - Alaska smoke forecast became operational.
09/15/2009 - Experimental NWS testing of Hawaii smoke forecast began running in an operational framework.
05/30/2008 - Experimental NWS testing of Alaska smoke forecast began.
12/19/2007 - General upgrade of HYSPLIT model code, MPI option enabled, and increased vertical resolution (sigma layers) of NAM meteorology introduced.
03/07/2007 - Smoke Forecast Product for CONUS transitioned into NWS operations.
08/19/2006 - Emission factor increased by a factor of 6.
06/20/2006 - NAM/ETA meteorology replaced by NAM/WRF meteorology.
05/24/2006 - Plume rise and GFS meteorological data were added to HYSPLIT. In addition, the calculated burn area algorithm was modified.
03/28/2006 - Experimental NWS testing of CONUS smoke forecast began.
01/11/2006 - Smoke runs from NCEP testing now used on this website.
01/05/2006 - Forecast now generated using the NAM AQM hourly forecast data.
10/06/2005 - Forecast now generated using the 0600 UTC NAM forecast data.
09/24/2005 - +24 hour forecast verification results began.
09/21/2005 - Compressed tar file of model concentration file began.
07/21/2005 - Hourly concentration output began.
07/01/2005 - Daily threat score and bias results started.
07/01/2005 - HMS plumes now can be turned on and off individually.
06/29/2005 - Updated SVG output to show 4 HYSPLIT contour levels.
05/29/2005 - 3-hourly concentration output of 24 hour analyses began.
