| 英文摘要: | This set of files includes downscaled projections of monthly totals, 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) at 771 x 771 meter spatial resolution. 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 1971-2000. |
