    * Information about the GEFS Model


    NN is the number (name) of ensemble members (c00, p01-p20)
    CC is the current cycle (00, 06, 12, 18)
    xxx denotes the forecast hour (i.e. 00, 06, ..., 384)
    PP refers to 10, 50 or 90
    YYYYMMDD refers to the current Year Month Day

The Inventory links contain detailed model information
Use as a guide when selecting specific parameters from NOMADS through the grib filter option
