Dataset
To provide data on groundwater storage change across the Indo-Gangetic basin.
The maps are produced by British Geological Survey (BGS).
Data contains estimated mean annual groundwater storage change (in cm) across the aquifer based on annual groundwater-level change and specific yield.
Data is based on in situ observations, statistical analyses of multiyear groundwater-level records from 3,429 water wells and modelling of existing high-resolution spatial datasets.
