84 years of monthly and yearly water balance projections from 2016 to 2099 for parts of Afghanistan, Tajikistan, Kyrgyzstan, and Pakistan. The University of New Hampshire Water Balance Model generated these projections using 12 CMIP6 global climate models under two socioeconomic scenarios. A historical model run from 1980 to 2018 is also included.
Use Cases
- Compare projected runoff and evapotranspiration under SSP 2-4.5 and SSP 5-8.5 scenarios for the Amu Darya basin.
- Analyze long-term trends in monthly water balance components like precipitation and snowmelt across 12 different CMIP6 models.
- Validate the water balance model by comparing the historical run (1980-2018) against observed basin outflow data.
- Assess inter-annual variability and climate model uncertainty in future projections for the Indus River headwaters.
Strengths
- Projections span 84 future years (2016-2099) and include a 39-year historical run (1980-2018).
- Data incorporates outputs from 12 different CMIP6 global climate models.
- Covers two distinct Shared Socioeconomic Pathways (SSP 2-4.5 and SSP 5-8.5).
Limitations
- Geographic coverage is limited to specific parts of four countries, not the entire High Mountain Asia region.
- Projection accuracy is contingent on the CMIP6 model inputs and the Water Balance Model's assumptions.
- The dataset's future projections extend beyond current validation capabilities.
