+The data layers were generated through interpolation of average monthly climate data from weather stations on a 30 arc-second resolution grid (often referred to as "1 km2" resolution). Variables included are monthly total precipitation, and monthly mean, minimum and maximum temperature, and 19 derived bioclimatic variables.[[BR]]
+Coevered period : 1950-2000[[BR]]
+
+The thin-plate smoothing spline algorithm implemented in the ANUSPLIN package for interpolation, using latitude, longitude, and elevation as independent variables was used.[[BR]]

+3000 monthly station temperature time series are used. The number of available stations was small during the 1850s, but increases to over 3000 stations during the 1951-90 period.[[BR]]

+Annual values are approximately accurate to +/- 0.05°C (two standard errors) for the period since 1951.[[BR]]
