| Summary: | This data set provides estimates of daily mean two meter air temperature from the European Center for Medium Range Weather Forecasts (ECMWF) ERA-40 Reanalysis (ECMWF 2002). Data cover the period 1 January 1979 to 31 August 2002. Data were obtained from the National Center for Atmospheric Research (NCAR) Data Support Section, dataset ds117.0 (). Two meter temperatures are archived as 6 hour mean values. Daily means were computed from these values. Data were regridded from the native N80 (roughly 1 degree resolution) reduced Gaussian grid to the Equal-Area Scalable Earth (EASE) 25km grid using a bilinear interpolation scheme. This scheme is described in ECMWF [2003]. The ERA-40 system assimilates available surface temperature observations. Fields should therefore be superior to those from the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) Equal-Area Scalable Earth Grid (EASE-Grid) re-analysis, in which there is no assimilation of surface temperature data. The data is presented in 24 sub-datasets of different spatial and temporal aggregations. |
