China meteorological forcing dataset (1979-2018)

The China Meteorological Forcing Dataset (CMFD) is a high spatial-temporal resolution gridded near-surface meteorological dataset that was developed specifically for studies of land surface processes in China. The dataset was made through fusion of remote sensing products, reanalysis dataset and in-situ observation data at weather stations. Its record starts from January 1979 and keeps extending (currently up to December 2018) with a temporal resolution of three hours and a spatial resolution of 0.1°. Seven near-surface meteorological elements are provided in CMFD, including 2-meter air temperature, surface pressure, specific humidity, 10-meter wind speed, downward shortwave radiation, downward longwave radiation and precipitation rate.

National annual average surface temperature and freezing index by remote sensing (2008)

The 2008 national remote sensing annual average surface temperature and freezing index is a 5 km instantaneous surface temperature data product based on MODIS Aqua/Terra four times a day by Ran Youhua et al. (2015). A new method for estimating the annual average surface temperature and freezing index has been developed. The method uses the average daily mean surface temperature observed by LST in morning and afternoon to obtain the daily mean surface temperature. The core of the method is how to recover the missing data of LST products. The method has two characteristics: (1) Spatial interpolation is carried out on the daily surface temperature variation observed by remote sensing, and the spatial continuous daily surface temperature variation obtained by interpolation is utilized, so that satellite observation data which is only once a day is applied; (2) A new time series filtering method for missing data is used, that is, the penalty least squares regression method based on discrete cosine transform. Verification shows that the accuracy of annual mean surface temperature and freezing index is only related to the accuracy of original MODIS LST, i.e. the accuracy of MODIS LST products is maintained. It can be used for frozen soil mapping and related resources and environment applications.

Great lakes in Central Asia-Basic dataset-climate-2016

Meteorological data is a group of data reflecting the weather, which can be divided into climate data and weather data. This data set mainly includes the rainfall data and temperature data in the meteorological data (pre represents rainfall and T2 represents temperature in the data set). This data set is from the CRU (climate research unit) global grid data provided by the University of East Anglia in the UK ( Cru data set is obtained by interpolating the data of 365 observation stations in Central Asia, which has high accuracy in Central Asia. This data set uses CRU to obtain rainfall and temperature data of five Central Asian countries through ArcGIS batch cutting. Data format: GeoTIFF; spatial resolution: 0.5 °; time scale: Monthly Scale. The meteorological data is widely used and can be integrated with resources in different fields.
