- Global Average Monthly Temperature (°C) for HADCM3 SRES A2 at a ½ Degree Grid Resolution, 2070-2099
Global Average Monthly Temperature (°C) for HADCM3 SRES A2 at a ½ Degree Grid Resolution, 2070-2099
- Description:
- For each HADCM3 gridcell: A 12-month average temperature was calculated for 1961-1990 based on the simulated transient historical data. Result is a 12 month simulated climatology at the scale of the HADCM3 grid.
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 HADCM3 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.
- Data Provided By:
- Mean historical temperatures were derived from Climatic Research Unit TS 2.0 half degree grids (website: http://www.cru.uea.ac.uk ). Future temperature anomalies were calculated from simulated historical and projected future temperatures produced by the HADCM3 model running on historical and SRES A2 CO2 levels. Downscaling was done by Raymond Drapek, PNW Research Station, USDA Forest Service.
- Content date:
- Original dataset covers the years 2000-2099. This particular map is the average for the years 2070-2099.
