Data analysis: Cropped from national scale to just California Coast by Fred Watson, in Arc ASCII GRID format.
Map produced by:
Base map compiled by Erin Stanfield, Fred Watson, Wendi Newman.
Base map:
- Projected Coordinate System: NAD_1983_UTM_Zone_10N
  - Projection: Transverse_Mercator
Precipitation map:
- Geographic Coordinate System: GCS_North_American_1983
  - Datum: D_North_American_1983
