ERA40 Model Resolution Gridded Surface, Vertical Integrals, and Other Single Level Fields from ECMWF
Precip, Fluxes, Stresses and Radiation Fields

These variables are described in terms of the ECMWF GRIB Code Table 128.

The accumulation period for all of the accumulated fields in this dataset is 6 hours starting at the analysis time. To compute instantaneous values for the accumulation fields, divide all data values by 21,600 seconds.
