Three sets of historical reanalysis climate datasets in Central Asia (1979-2014)
The Central Asia climate data set comes from three recently developed global reanalysis data sets. Merra uses the latest version of the global earth observation system (GEOS-5), which can absorb satellite radiation and conventional observations. Era interim is a global land surface reanalysis data set, which is generated at T255 (80km) horizontal resolution. The product update is about one month delayed from real-time. CFSR is one of the latest global reanalysis climate data sets, which has been widely used in climate change research. These datasets have different spatial resolutions and cover 1979-2014. Atmospheric reanalysis data is driven by a variety of data, combined with observation data under strict quality control, using data assimilation techniques and numerical prediction models to obtain historical observation data. In recent years, the new generation of historical reanalysis data is suitable for studying the climate pattern of Central Asia with high spatial heterogeneity of precipitation and complex topography due to its high spatial resolution.

Three sets of historical reanalysis climate data sets are stored in grid format. The file names are: ppt day represents daily precipitation; Rhum represents daily relative humidity; SRAD represents daily solar radiation; tavg represents daily average temperature; v1979 represents 1979; v1979d1 represents the first day of 1979. Read mode: open grid file with ArcGIS.
