Release Notes: ETSS v2.2.0 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 - Implemented on Oct.15, 2014 a) Using GRIB2 0.5 degree GFS data instead of GRIB1 1 degree GFS data b) Bug fix for wind control window for Arctic basin c) Additional output of 2.5 km CONUS grids (requiring a new mask file) d) Additional output of 3 km Alaska grids (requiring a new mask file) e) Correcting the Alaska mask files in the south Bering Sea v2.0.0 - Implemented on May 19, 2015 a) Re-introducing the inundation algorithm based on surge b) For the East and Gulf of Mexico coastlines, nesting the tropical and Extra-Tropical computational grids to leverage the finer overland details contained within tropical grids c) ETSS post processing is being introduced to the operational environment to create SHEF-encoded water level guidance for River Forecast Centers d) ETSS post processing now uses NCEP's BUFR tanks (as opposed to web scraping) for observations v2.1.0 - Implemented on November 3, 2015 a) Creating a new Bering-Beaufort-Chukchi Sea (eBBC) Alaska basin to Resolve a problem with water flowing from one basin to another through the Bering Strait. b) Determine best wind drag coefficient to use for eBBC c) Re-introducing the inundation algorithm based on surge and tide d) Provide overland guidance based on surge and tide for all U.S coastlines, which include tidal forcing for all domains e) Correct the SHEF encoding to use MLLW instead of MHHW as a vertical datum, and incorporate more stations v2.2.0 - Code handoff #1 on February 29, 2017 - Target Implementation date June 06, 2017 a) Create a single basin with overland information that covers Gulf of AK and West Coast b) Create a new Tide version to resolve tide phase shift in CD2, ETP3 and AP3 c) Removed the reported storm surge 'wiggle' for the East Coast and Gulf of Mexico in version 2.1 d) Experimentally generate max surge + tide above NAVD88 for 0 ~ 102 hours e) Extend forecast from 96 to 102 hours (to match P-Surge 2.6 (2016)) f) Migrate to Cray g) Discontinue (a) 5.0 km CONUS and (b) 6.0 km AK grids as AWIPS (16.1.1; Dec 15, 2015) will no longer need h) General Enhancements / Bug fixes (-check bounds IT test, improve merge mask, make adjustments to the CSV files so they are self-describing and remove a bug in the linear interpolation for the post-processing codes) Input data changes: None Output changes: Extend output from 96 to 102 hours for gridded and text products Additional output of maximum Surge + Tide above NAVD88 for 0-102 hours on CONUS grids (2.5km and 625m) and Alaska grids (3km) Add WMO headers to get gridded data into AWIPS (surge+tide on CONUS 2.5km/625m and Alaska 3km grids, TideOnly on CONUS 625m grid) Discontinue (a) 5.0 km CONUS and (b) 6.0 km AK grids Computational resource information: Number of CPU: Increase to 14 CPU (No change) Memory: Increase to 1600 MB / CPU (No change) Serial/Parallel runs: 14 independent scripts run in parallel Run Time: 28 minutes (from 37 minutes) Disk space required: 1.0 Gig for disseminated data 17.0G per cycle for working folder folder How often: 4 cycle per day Dependencies: (a) GRIB2 library in /nwprod/lib, (b) /nwprod/util/exec/tocgrib2, (c) tocgrib2super Data retention for files in /com and /nwges under prod/para/test environments: A few weeks Preimplementation testing requirements: /dev/runETSS.sh, /dev/runPost_ETSS.sh and /dev/runETSS_gempak.sh should be tested as part of this implementation Does this change require a 30-day evaluation? Likely The suggested evaluators: AK-HQ, AK-WFOs, MDL, OPC 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: a) The GRIB files (etss.t${cyc}z*.grib2) b) Station output files (mdlsurge.${cyc}* and etss.t${cyc}z*.txt) c) Shef and CSV files (etss.t${cyc}z*.shef_tar and etss.t${cyc}z*.csv_tar)
