CIMIS Web

The CIMIS Web API is a RESTful service that provides access to data about evapotranspiration (ETo) and weather from the CIMIS Weather Station Network and the Spatial CIMIS System. CIMIS stands for the California Irrigation Management Information System. The API can be used to operate Wi-Fi aware irrigation smart controllers, browser and mobile apps. The CIMIS Web API is managed by the California Department of Water Resources (DWR).
