CRU-TS 3.1 Climate Database

In April 2011, the University of East Anglia released the CRU-TS 3.1 Climate Database (See the official data release at http://badc.nerc.ac.uk/data/cru). This new version of database covers from 1901 to 2009, globally at 0.5 degree spatial resolution on land areas. To help facilitate the use of this database in the CSI community using GIS software, we have converted the raw data of NetCDF data files into the ESRI ASCII raster format.

The database contains following ten variables:

Label	Variable	Unit	Scaling Factor
cld	cloud cover	%	10
dtr	diurnal temperature range	degree Celcius	10
frs	frost day frequency	days	100
pre	precipitation	mm	10
tmp	daily mean temperature	degree Celcius	10
tmn	monthly average daily minimum temperature	degree Celcius	10
tmx	monthly average daily maximum temperature	degree Celcius	10
vap	vapour pressure	hecta-Pascals	10
wet	wet day frequency	days	100
pet	potential evapotranspiration	mm	10

Note that each variable was scaled by the factor 10 or 100 to store as integer. Other than converting the file format, data values have not been modified from the original data. If you feel comfortable working with NetCDF format, we recommend you to use the original data files from the official website, where you can also access additional data layers including the number of weather stations used in each cell.
