Global 1 km resolution daily near-surface air temperature for 2021

A gridded 1 km resolution global (50°S ~79°N) daily maximum and minimum near-surface air temperature dataset for 2021 that was generated using a seamless 1 km resolution land surface temperature dataset, a 30-arc second (~1 km) resolution digital elevation model (DEM) data, and air temperature observations at weather stations and a spatially varying coefficient model with sign preservation (SVCM-SP) algorithm.The gridded air temperature dataset is of great use in global studies of urban, climate, and hydrology.Documentation for this dataset can be found with the 2003 data.
