For each forecast month a difference anomaly was calculated (ex. January_2021 – Mean_historical_January). Result is a 100 year monthly set of temperature anomalies at the scale of the MIROC grid.
For each forecast month: Gridded anomalies were interpolated to a ½ degree grid using a bilinear interpolation. For each forecast month and each ½ degree gridcell: The anomaly for that month is added to the CRU historical mean temperature (ex. CRU_Mean_January_1961-1990 + January_2021_anomaly). Result is mean monthly temperature data for the years 2001-2100 at the ½ degree grid.
An average of the years 2070-2099 was produced. Result is a single map of the average temperature values.
There is no citation for the downscaled data as of 2/7/11, but a Forest Service General Technical Report is in progress. Citation for the CRU data: Mitchell, T.D., Carter, T.R., Jones, P.D., Hulme,M., New, M., 2003: A comprehensive set of high-resolution grids of monthly climate for Europe and the globe: the observed record (1901-2000) and 16 scenarios (2001-2100). Journal of Climate: submitted. MIROC were picked up from the WCRP CMIP3 multi-model database website (https://esg.llnl.gov:8443/home/publicHomePage.do).
