The current NCEP SREF has 10 members, runs twice a day (09z and 21z)
at a forecast length of 63hr with 48km Eta (5 members) and RSM (5 members)
regional models. Three types of
ensemble products are available now for selected variables: (1) Mean and
Spread; (2) Spaghetti Diagrams; and (3) Probability Charts.
More ensemble products will be developed in future. If you have any
suggestions or requests about ensemble products, welcome to contact us
at Jun.Du@noaa.gov or Steve.Tracton@noaa.gov.
!!!Alert: Due to random date
mismatch in the automated process of creating this large sum of gif files
(about 9000 gif files each forecast cycle), some weired, non-meteorological
images might be mysteriously produced sometimes (although the model output
such as grib data is good). If this happens, please ignore those nonsense
products and double check with the same kind of products but from other 2
ensembles such as Eta sub-ensemble and RSM sub-ensemble. Sorry about this
annoyance and please accept our apology. We are doing our best to prevent
this from happenning.!!! (Nov. 21, 2001, Jun Du).
