Parameters for ds119.0 ERA40 Monthly Mean Model Resolution Gridded Surface,Single Level and Vertical Integral Analysis from ECMWF

ERA40 Monthly Mean Model Resolution Gridded Surface Fields and Vertical Integrals from ECMWF
Surface and Near Surface Variables

There are 47 Monthly Mean Surface and Single Level variables described in terms of the ECMWF GRIB Code Table 128.

Note that parameter 207 - 10 meter wind speed is ONLY available from the Model Resolution Surface and Single Level monthly means. It is NOT available in ANY of the daily analysis' or the 2.5 degree monthly mean data.
