The global freshwater availability trend of the Gravity Recovery and Climate Experiment (GRACE) from 2002 to 2016 is a global grid dataset with a spatial resolution of 0.5 degrees. Based on data obtained by NASA GRACE from 2002 to 2016, the trend of freshwater availability is presented; Obtain the trend of freshwater supply in the Heilongjiang River Basin through clipping; The available storage capacity of land water is the sum of groundwater, soil moisture, ice and snow, surface water, and wet biomass, expressed in terms of water equivalent height. Unit: cm; Space coordinate system: WGS 84; Data source: https://sedac.ciesin.columbia.edu/data/set/sdei-trends-freshwater-availability-grace
