comments
It is derived by the interpolation of monthly climate anomalies from weather station observations, using angular-distance weighting. It is using the 1961–1990 period as reference for the anomalies. The resulting gridded anomalies are converted to actual values. Provides values for Tmean and diurnal temperature range. Tmin, Tmax are provided as derived products. CRU TS4.00 is a full release, differing in methodology from the v3.24.01. release.
