What we do

… and how we do it

Assessing and projecting changes in HMA’s water, ice, snow, hazards, and related phenomena to improve our understanding of regional changes, water resources, and induced impacts and vulnerabilities in human and biogeophysical systems.

Using open source science approaches to accelerate advances, foster transdisciplinary research and ensure FAIR (findability, accessibility, interoperability, and reproducibility) practices.
