Future water-supply projections, Central Asia mountains (2016-2099)

High Mountain Asia CMIP6 Monthly and Yearly Water Balance Projections, 2016-2099 for Parts of Afghanistan, Tajikistan, Kyrgyzstan, and Pakistan V001
hydrosphere NASA NSIDC_CPRD Level 4 netCDF-4
In plain English

What it measures. Projections of the water balance — how water moves and is stored — for mountain headwater regions of Afghanistan, Tajikistan, Kyrgyzstan and Pakistan, given monthly and yearly out to 2099.

How it's made. Generated by a university water-balance computer model driven by 12 global climate models under two future emissions scenarios, with a historical run for comparison; this is model output, not satellite data.

How & where you'd use it. Helps water managers and researchers anticipate future water supply in the Amu Darya and Indus headwaters under different climate futures.

Official description

This High Mountain Asia (HMA) data set comprises a suite of monthly and yearly water balance model (WBM) projections for the years 2016 – 2099, covering parts of Afghanistan, Tajikistan, Kyrgyzstan, and Pakistan (primarily the headwaters of the Amu Darya and Indus River basins). Projections are available for 12 Coupled Model Intercomparison Project Phase 6 (CMIP6) global climate models and two Shared Socioeconomic Pathways (SSP 2-4.5 and SSP 5-8.5). The data were generated using the University of New Hampshire WBM. A historical run is also available for the years 1980 through 2018, using as input ERA5 reanalysis temperature data and ensemble precipitation estimates.
