Historical Monthly and Derived Precipitation Products - 771m CRU TS

This set of files includes downscaled historical estimates of monthly totals, and derived annual, seasonal, and decadal means of monthly total precipitation (in millimeters, no unit conversion necessary) from 1901 - 2006 (CRU TS 3.0) or 2009 (CRU TS 3.1) at 771 x 771 meter spatial resolution.

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

Brief descriptions of the datasets:

Monthly precipitation totals: The total precipitation, in mm, for the month.

For Decadal outputs:
1. Decadal Average Total Monthly Precipitation: 10 year average of total monthly precipitation. Example: All January precipitation files for a decade are added together and divided by ten.
2. Decadal Average Seasonal Precipitation Totals: 10 year average of seasonal precipitation totals. Example: MAM seasonal totals for every year in a decade are added together and divided by ten.
3. Decadal Average Annual Precipitation Totals: 10 year average of annual cumulative precipitation.

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)
