        * 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
