CRUTEM is a set of data derived from air temperatures near the Earth’s surface recorded by weather stations on all continents of the Earth. It has been developed and maintained by the Climatic Research Unit since the early 1980s, with funding provided mainly by the United States Department of Energy.
The latest version of CRUTEM is called CRUTEM4 and is available in text and netCDF format from the Climatic Research Unit at the Met Office Hadley Centre.
But CRUTEM4 can also be accessed through Google Earth, just download a KML file and open it in Google Earth, and to query or download anywhere in the world, just click on the desired location.
The weather variables for which information can be obtained free of charge are as follows:
- Diurnal temperature range
- Vapour pressure
It should be noted that the resolution depends on the observed and synthetic stations for each site. For more information, please read carefully the news of CRUTEM4.
