NCEP Modeling Synergy Meeting Highlights: September 29, 2008
This meeting was led by Mike Brennan and attended by John Ward, Geoff DiMego, Dan Starosta, Chris Magee, Bill Bua, Joe Sienkiewicz, Keith Brill, Jim Hoke, Zoltan Toth, Vera Gerald, and Mary Hart. Stephen Jascourt of UCAR/COMET, Steve Weiss and David Bright of SPC, Jeff Waldstreicher of Eastern Region, and Carven Scott from Alaska Region attended by remote teleconference.
Chris Magee of NCO reported on several ongoing/upcoming implementations:
· The 30-day parallel evaluation period for the RUC upgrade was restarted on Friday, Sep. 26, due to a script error that prevented the assimilation of TAMDAR and Level-II WSR-88D data into the model
· NCO and EMC are working to get the SREF upgrade into a real time parallel
delivered for a
· Code was delivered for a GFS/GSI upgrade last Friday
· An upgrade to HYSPLIT is being worked on
The RTMA for
· Upgrades to the RTOFS and Great Lakes Wave Model are scheduled to be implemented in the 1st Quarter of FY09
· A RFC was received from MDL for the LAMP model – A TIN was advertised with an implementation scheduled for 12 November
NCO is awaiting
· The NGM MOS is tentatively scheduled to be turned off on 3 March 2009
· If NAM MOS is working properly, the 32-km Eta model runs that support the Eta MOS will be turned off in December 2008
Please note that the usual December “holiday” change moratorium will last through April 2009 due to the implementation of the new Power 6 supercomputer.
A detailed list of all upcoming major upgrades and implementations can be found here.
2. NOTES FROM EMC
2a. Global Climate and Weather Modeling Branch
John Ward reported on several notes from the GCWMB:
John emphasized that the timing of the GFS and HWRF upgrades is dependent on the implementation of the new Power 6 supercomputer.
2b. Mesoscale Modeling Branch
DiMego reported that RFCs are forthcoming to unify the RTMA version running for
CONUS/Alaska with that running for
also noted that with the implementation of the Power 6, there is a plan to
double the resolution of the RTMA to 2.5 km for the CONUS, 2.9 km for
The current RUC parallel is assimilating 3-D reflectivity mosaic radar data through a digital filter with this upgrade.
upcoming NOAA profiler data outage is expected to have a “significant” impact
on the RUC performance according to GSD. The RUC is the only model that
assimilates both the wind and RASS temperature data, while the GFS and

2c. Global Ensemble Prediction System
Zoltan Toth reported that RFCs have been submitted for an upgrade to the Global Ensemble Forecast System (GEFS) that was detailed during the last couple of Synergy Meetings. One change is that this upgrade no longer includes the once daily extension of the GEFS run out to 35 days.
The next GEFS upgrade will include realtime hindcasts for bias correction and new post processing for day 5 and beyond. The GEFS will also be coupled to the MOM4 ocean model if this implementation is successful in the GFS.
Geoff reported that implementing hourly output for the current SREF upgrade at the request of SPC and AWC has been a challenge, but had to be done in this upgrade if it was going to be available by spring 2009. This change doubled the product generation time for the SREF, but work is ongoing to reduce that impact.
2e. Marine Modeling and Analysis Branch
Gerald reported that the evaluation of the Great Lakes Wave Model
implementation using NDFD winds has gone well. This model will replace the
current Great Lakes Wave Model that uses
reported that the planned RTOFS upgrade includes changes that will improve the
location of the
3. FEEDBACK FROM OPERATIONAL CENTERS/REGIONS
Joe Sienkiewicz asked if the parallel RTOFS data are available in GEMPAK format. Vera replied that she did not think so. Joe will investigate further.
Steve Weiss asked for clarification on the ingest of Level II radar data into the ongoing RUC parallel. Chris Magee confirmed that these data are indeed being ingested for the parallel.
4. The next Synergy Meeting will be held Monday, October 27, 2008, at 12:00 pm EDT in Room 209 at EMC, with remote conference capability.
