ECMWF 40 Year Re-analysis (ERA-40) Full Resolution Potential Vorticity Levels Analysis Data Set



 

 
  This part includes a brief description and the order forms of this specific Data Set.

Description :

  • fields are analyses for 0000 UTC, 0600 UTC, 1200 UTC and 1800 UTC each day;
  • data are stored in FM 92 GRIB using sufficient bits to ensure that the values represented can be retrieved to an accuracy consistent with the analysis method used;
  • Internal data are represented on a N80 Gaussian grid (80 lines of latitude, located according to a Gaussian distribution between the pole and the equator for each hemisphere);
  • To learn more about potential vorticity levels read on >>

Fields available are:

geopotential, ozone mass mixing ratio, potential temperature, pressure, specific humidity and u- and v-components of horizontal wind.
