The ORNL DAAC announces the addition of "Global Monthly Climatology for the Twentieth Century (New et al.)" to its collection of climate data.
The newest addition contains gridded data related to monthly surface climate over global land areas at 0.5-degree resolution. Precipitation, mean temperature, and diurnal temperature range are interpolated directly from station time-series. Wet-day frequency, vapor pressure, cloud cover, and ground-frost frequency are interpolated where data are available and estimated for regions with no data.
Data can be accessed through an on-line interface that allows users to select the data by parameter and years. By agreement with the data provider, users who wish to request the complete 400-megabyte data set on a CD-ROM should contact the Climate Research Unit at the University of East Anglia, U.K.
The twentieth century data set complements two other data sets recently added to the ORNL DAAC holdings: "Global 10-Year Mean Monthly Climatology, 1901-1990 (New et al.)" and "Global 30-Year Mean Monthly Climatology, 1901-1960 (New et al.)."
