Climatic Research Unit (CRU) TS Time-Series 4.04

The gridded Climatic Research Unit (CRU) Time-series (TS) data version 4.04 data are month-by-month variations in climate over the period 1901-2019, provided on high-resolution (0.5x0.5 degree) grids, produced by CRU at the University of East Anglia.
The CRU TS4.04 variables are cloud cover, diurnal temperature range, frost day frequency, potential evapotranspiration (PET), precipitation, daily mean temperature, monthly average daily maximum and minimum temperature, and vapour pressure for the period January 1901 - December 2019.
The CRU TS4.04 data were produced using angular-distance weighting (ADW) interpolation. All version 4 releases used triangulation routines in IDL. Please see the release notes for full details of this version update.
The CRU TS4.04 data are monthly gridded fields based on monthly observational data calculated from daily or sub-daily data by National Meteorological Services and other external agents. Files contain monthly mean values for the various parameters. They contain an additional integer variable, "stn", which provides, for each datum in the main variable, a count (between 0 and 8) of the number of stations used in that interpolation. The missing value code for 'stn' is -999.
All CRU TS output files are actual values - NOT anomalies.

Use of these data is covered by the following licence:

When using these data you must cite them correctly. Please refer to 00README_catalogue_and_licence.txt <
