This part includes a brief description and the order forms of this specific Data Set.
Description :
- These data sets contain uninitialised analysis values interpolated to a 2.5° x 2.5° regular latitude/longitude grid. This grid is co-located with the 5° x 5° and 2.5° x 2.5° grids used for ECMWF data distribution daily on the Global Telecommunications System (GTS).period supported - 1 January 1985 to current date;
- fields are uninitialised analyses for 0000 UTC and 1200 UTC each day;
- each parameter at each level is stored as a field of grid point values on a 2.5° x 2.5° regular rectangular mesh in latitude rows starting at the north and working southwards; within each row values run from west to east starting at the 0° meridian;
- data are stored in FM 92 GRIB using sufficient bits to ensure that the grid point values can be retrieved to an accuracy consistent with the analysis methods used;
- production of the archive has been made as automatic as possible using techniques which enable the data sets to be updated monthly.
The Consolidated Data Set contains data corresponding to the Upper-Air Data Set together with data comprising the Surface Data Set.
The mode of storage of the Consolidated Data Set within the archive is such that data must be retrieved globally, for all parameters, all levels, and in monthly units.
| 1 January 1985 | Surface data is surface pressure, soil temperature level 1, MSL pressure, u- and v-components of wind at 10m, temperature at 2m, dewpoint at 2m, surface geopotential and land-sea mask Upper air data is 14 standard pressure levels, 1000, 850, 700, 500, 400, 300, 250, 200, 150, 100, 70, 50, 30 and 10 hPa geopotential, temperature, vertical velocity, u- and v-components of horizontal wind, and relative humidity at each level |
| 1 January 1992 | pressure level, 925 hPa added |
| 1 April 1999 | pressure
levels 20, 7, 5, 3, 2 and 1 hPa added
