PALAEO-RA – Global Climate of the Past Six Centuries

Data access

Monthly global gridded 3D reconstructions based on upper-air and surface data, 1918-2000

Description: Monthly gridded reconstruction of temperature, geopotential height, u- and v-wind at five levels (850, 700, 500, 300, 200, 100 hPa) based on calibrating, for each grid column, a statistical model using upper-air and surface data surrounding that column against ERA40. After 1957, the file contains the calibration.
