NCAR's Research Applications Laboratory

Computational Hydrology

Research to improve the fundamental building blocks on which hydrometeorological analyses and climate assessments depend.

Welcome. This site provides an integrated collection of tools to advance continental meteorological analyses, hydrologic modeling & parameter estimation, hydrologic prediction techniques, and weather & climate downscaling. Collectively, these provide a foundation to improve our understandings and make water and energy systems more resilient.
