Release Notes: ETSS v1.5.0 v0.0.0 - Initial implementation of Model -- Oct 3, 1995 v0.0.0 - West Coast and Arctic added -- Sep 25, 2000 v0.0.0 - Handle all 4 cycles of GFS -- Sep 1, 2001 v0.0.0 - More development by Jye Chen until Aug, 16, 2002 V0.0.0 - Changing model to handle 96 hours forecast -- May 10, 2007 v0.0.0 - Output to NDFD grids -- Nov 7, 2007 v0.0.0 - Updating east coast basin and adding Gulf of Alaska basin -- April 11, 2008 v0.0.0 - Updating Gulf of Mexico basin -- Jun 30, 2010 v0.0.0 - Adding scripts to run ETSS model in parallel -- Jan 21, 2011 V1.0.0 - WCOSS Transition --- by Arthur Taylor, Oct 11, 2012 modified model to run on WCOSS v1.5.0 - by Huiqing Liu, May 18, 2014 Input data changes Using GRIB2 GFS data instead of GRIB1 0.5 degree GFS data instead of 1 degree bug fix for wind control window for Arctic basin GRIB2 library instead of using GRIB1 library located in /nwprod/lib Interpolate higher resolution (0.5 degree) GFS data to ETSS grid Output changes Additional output of 2.5 km CONUS grids (requiring a new mask file) Additional output of 3 km Alaska grids (requiring a new mask file) Correcting the Alaska mask files in the south Bering Sea Computational resource information: Number of CPU: <No Change> (2 CPU) Memory: Increase to 200 MB / CPU (from 100 MB) Serial/Parallel runs: 2 independent scripts run in parallel Run Time: 4-6 minutes Disk space required: 1.0 Gig for disseminated data (5.0G per cycle for working folder folder (ETSS1.5/work/tmp/) How often: 4 cycle per day Dependencies: (a) GRIB2 library in /nwprod/lib, (b) /nwprod/util/exec/tocgrib2 Data retention for files in /com and /nwges under prod/para/test environments: A few weeks. Preimplementation testing requirements runETSS.sh should be tested as part of this implementation Does this change require a 30-day evaluation? Unlikely The suggested evaluators: MDL, OPC, NHC, WFOs Include dissemination info Where should this output be sent? SBN Primary users: WFO and OPC Archive to HPSS Retention length: Few years List which output files should be archived: The GRIB files (grib2.mdlsurgegrid*)
