CRU-TS 3.0 Climate Database

In January 2010, the University of East Anglia officially released the CRU-TS 3.0 Climate Database (See the official data release at http://badc.nerc.ac.uk/data/cru). This new version of database covers from 1901 to 2006*, 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 into the ESRI ASCII raster format.

The database contains following nine variables. Each variable was scaled by the factor described in the table to store as integer.

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
