Climate Change Impacts on Water Availability in Alaska

What we did

The Wilderness Society used SNAP data and assistance to assess potential future impacts on water availability statewide.

What we found

These data provide high-resolution historical estimates and projections of potential evapotranspiration (PET) for Alaska, filling a need to provide high-resolution PET inputs for hydrological and ecological models that require them.

What this may mean

The PET projections may identify areas where there is potential for marked changes or where projections diverge, and where mechanistic studies may help us better understand the impact of climate change on the local water balance and the many ecological processes it influences.
