Global Historical Climatology Network (GHCN)

About data

Monthly climate data for thousands of worldwide weather stations. Data are available for each station and also gridded (onto 5x5 degree cells).

The Global Historical Climatology Network (GHCN-Monthly) data base contains historical temperature, precipitation, and pressure data for thousands of land stations worldwide. The period of record varies from station to station, with several thousand extending back to 1950 and several hundred being updated monthly via CLIMAT reports. The data are available without charge through NCDC’s anonymous FTP service.


Compressed plain text, fixed width columns.


From .gov site, and US government department, so one would assume a fair amount in the public domain. However, data is aggregated and includes non-US sources, so this should be clarified.
