Excuse me if am posting to the wrong list, but I am assuming many of the
people on this list run the WRF model. I have been having problems lately
with data to run WRF
The model was running very well with data from
http://nomad3.ncep.noaa.gov/pub/gfs/rotating-grb2/ (alternative being
http://nomad3.ncep.noaa.gov/pub/gfs/rotating-0.5/). However, since 7th
August
the data on these addresses were updated no more.
Then I tried http://nomad5.ncep.noaa.gov/pub/gfs/gfs20120820/ where
the date changes daily, but from 20th there is no more update.
Claudio kindly gave me
ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gfs.2012082800/ but
as of 29th there is no more update. I wonder what is happening. would
someone have some idea?
Thanks
