RSM Ensemble

The RSM component of the NCEP SREF upgrade II system has 5 members from two physics packages -- SAS (ctl, n1 & p1) and RAS (n2 & p2), runs twice a day (06z and 18z) at a forecast length of 63hr with 32km RSM model. 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 at Jun.Du@noaa.gov.
