Dataset of ERA-interim global surface air temperature reanalysis (1979-2016)

Dataset of ERA-interim global surface air temperature reanalysis (1979-2016)

The data set of ERA-Interim global surface air temperature reanalysis (1979-2016) was obtained from the European Center for Medium-Range Weather Forecasts (ECMWF) by adopting the ECMWF IFS forecasting system (T255, 60 layers) and using the four-dimensional variational assimilation system (8DVAR) with an analysis window of 12 hours to assimilate satellite remote sensing data (TOVS, GOES, Meteosat, etc.) and regular observations of the surface and upper atmosphere in different regions of the world and from different sources. The surface air temperature (2 m air temperature) data span the time range from January 1979 to December 2016 and cover the whole world with the projection of equal latitude and longitude, a temporal resolution of six hours, and a horizontal resolution of 0.75. The data were stored as a NetCDF format file once a month and included longitude, latitude, time, and temperature (t2m, unit: K), with 241 latitudinal grid points and 480 longitudinal grid points.

File naming and required software

File name: the data is stored in the format of NetCDF. The file name is interim-t2m, where yyyy represents the year and DDD represents the day. For example, represents the temperature data of the first day of 1979
Data reading mode: the data can be opened programmatically or directly by arcgis and other software.
