Historical Monthly and Derived Temperature Products Downscaled from CRU TS data via the delta method - 2 km

This set of files includes downscaled historical estimates of monthly average, minimum, and maximum temperature and derived annual, seasonal, and decadal means of monthly average temperature (in degrees Celsius, no unit conversion necessary) from 1901 - 2006 (CRU TS 3.0) or 2009 (CRU TS 3.1) or 2015 (CRU TS 4.0) at 2km x 2km spatial resolution. CRU TS 4.0 is only available as monthly averages, minimum, and maximum files.

For seasonal means, the four seasons are referred to by the first letter of 3 months making up that season:

  • JJA: summer (June, July, August)

  • SON: fall (September, October, November)

  • DJF: winter (December, January, February)

  • MAM: spring (March, April, May)

The downscaling process utilizes PRISM climatological datasets from 1961-1990.
