Global Climate Data

Submitted by ORNL DAAC Staff on 1999-05-05
The climate data at the ORNL DAAC are used primarily as driving variables in terrestrial biogeochemistry models. These models typically use data on temperature (min,max), precipitation, humidity (relative humidity, vapor pressure deficit, dew point), radiation (PFD in PAR, shortwave, direct/diffuse, and UV radiation, daylength), and wind velocity. Climate / meteorology data are required at hourly to monthly time scales, either point or gridded, at spatial scales ranging from regional to continental to global.

The ORNL DAAC currently distributes climate data from several related projects:

We are also now distributing climate data developed at the East Anglia Climate Research Unit and the Potsdam Institute for Climate Research.

Data are available through Searching for Global Climate Data on the ORNL DAAC web site.
