LDAS Meeting
Minutes
September 15th, 2000, at NCEP
Participants: NOAA, NASA, PRINCETON, U.Washington (video conference), Rutgers University, COLA
1) Next meeting Monday, November 6th 2000, NASA 1pm
2) Ken updated LDAS output document, see LDAS homepage
http://ldas.gsfc.nasa.gov
3) Ken discusses Curtis' grib output template. Each group
has to change the PDS section to their own model. For the next
meeting there should be a working version available.
Contact for the groups are: Dag, Brian, Justin and Yun
4) Dennis and Andy show their seasonal forecast experiments with
VIC. A Powerpoint file is available to show more details.
Comparison of precip, wind, and temperature between EDAS
and measured data show that the EDAS wind speed is too high.
5) DMIP: feedback is needed by September 22nd. 8 years of hourly
forcing, NCDC data for precip, problems exist with the estimation
of PET.
6) Dag shows 188 selected basins and will distribute basin list.
realtime streamflow is available in
http://lnx69.ncep.noaa.gov/LDAS/STREAMFLOW
Snow data: Global USAF, northern hemisphere NESDIS IMS, NOHRSC
Ken will send out information.
7) Sid Katz shows distribution of realtime GTS gauges, problems with
restricted data in Mexico, most data are in local time which causes
extra problems. Could there be an updated product with more precip
stations for LDAS with a slightly bigger lag time? Sid will report
to Dag about this for next meeting.
600 snowtel sites in the W-region, 500 of these are used for
precip estimates.
8) Yun: Canada, USA, Mexico mask. Forcing has to be changed to that mask.
9) Paul and Brian: no specific humidity output from EDAS between Feb. 97 and Jun. 97
Action item for next meeting: everybody has to look at vegetation
parameters on LDAS homepage.
10) Lifeng: 98-99 OK Mesonet data, daily aggregates. see figures in

Rutgers group requests model output.
