Changes to the EDAS Archive

01-01-97 -- Archive Started
03-01-99 -- SOLW changed from 0-10cm Soil Moisture Content (fraction) to
                             0-200cm Soil Moisture Content (kg/m2)
         -- UMOF changed from U-flux of momentum to
                             USTR - Friction Velocity (m/s)
         -- VMOF changed from V-flux of momentum to
                             VSBY - Visibility (km)
         -- The Eta 40 km forecast is written to the EDAS archive first and
            then filled in with EDAS data if available, thereby reducing the
            number of missing records.
07-26-00 -- Confirmed by NCEP that the net latent and sensible heat fluxes
            are of opposite sign from convention, i.e. upward is negative. 
            The has been the case for the entire EDAS archive period and will
            continue to be the case in the future.  Note that this is 
            inconsistent with the FNL archive from NCEP.  The Eta forecast 
            dataset is also affected.
01-01-2004 -- Changed the EDAS from 80km to 40km and made the fields and levels the
            same as the ETA40 forecast.
04-30-2004 -- 80 km EDAS terminated and replaced by 40 km EDAS.
10-07-2020 -- Move original EDAS files with upward latent and sensible heat 
            fluxes set to a negative to old subdirectory. Create new EDAS files
            with upward latent and sensible heat fluxes set to a positive.
