Drought asymmetrically amplifies the lagged and cumulative vegetation productivity responses to soil and atmospheric droughts, stronger for vapor pressure deficit

This dataset contains the complete experimental process data and final result data for the paper **"Drought asymmetrically amplifies the lagged and cumulative vegetation productivity responses to soil and atmospheric droughts, stronger for vapor pressure deficit"**. The dataset covers China from 2001 to 2023. Gross primary production data was obtained from the GOSIF GPP dataset at 0.05° spatial resolution and monthly temporal resolution, available at http://globalecology.unh.edu/data/gosif-gosif-gpp.html. Land cover data was derived from the MODIS MCD12C1 product at 0.05° spatial resolution (https://doi.org/10.5067/MODIS/MCD12C1.006), and the 2012 land cover data was used to represent average vegetation conditions. Monthly climate variables including precipitation, potential evapotranspiration, soil moisture and vapor pressure deficit were obtained from the TerraClimate dataset at an original spatial resolution of 1/24°, and all variables were resampled to 0.05° to ensure spatial consistency.
