Southern Hemisphere dominates recent changes in global water availability

The datasets provides supports for the land water availability research. The trend in global water availability at grid: Ensemble_trend.tif and Ensemble_trend_p.tif. The annual global water availability from 2001 to 2020: WA _ensemble_annual.tif. The contribution of precipitation to the trend of water availability: CR_P.tif; Correlation between annual WA (detrend) and annual Southern Oscillation Index (SOI) at each 0.5° x 0.5 : WA_SOI_detrend.tif and WA_SOI_detrend_p.tif; The Aridity index: ai_v3_yr.tif; The trend in Lear area index: trend_LAI_MOD15A2_G050_smoothed.tif; The trend in P and ET: P_trend.tif and ET_trend.tif; The percentage of irrigation area is 30% or more: FIgure4_irrigation_30.tif; The coefficient of variation of precipitation: P_CV.tif. <br> <br>
