Climate and Hydrology Change Over Time: 2014 California BCM Deltas

The Basin Characterization Model (BCM) datasets provide historical and projected climate and hydrology at a 270 meter resolution. These data have formed the basis for multiple research projects and vulnerability assessments, providing a common set of assumptions across these projects.

This gallery features deltas (change over time) maps made from the BCM dataset, allowing for evaluation of the geographic patterns of change-- for example, areas where there is projected to be more or less relative change in heat, dryness, and rainfall in the future. These have been made available here to make it easy to create maps for climate adaptation plans and projects.
