CIMIS Weather Station & Spatial CIMIS Data - Web API

Description

CIMIS data is available to the public free of charge via a web Application Programming Interface (API). The CIMIS Web API delivers data over the REST protocol from an enterprise production platform. The system provides reference evapotranspiration (ETo) and weather data from the CIMIS Weather Station Network and the Spatial CIMIS System. Spatial CIMIS provides daily maps of ETo and solar radiation (Rs) data at 2-km grid by coupling remotely sensed satellite data with point measurements from the CIMIS weather stations. In summary, the data provided through the CIMIS Web API is comprised by a) Weather and ETo data registered at the CIMIS Weather Station Network (more than 150 stations located throughout the state of California and b) Spatial CIMIS System data that provides statewide ETo and solar radiation (Rs) data as well as aeraged ETo by zip-codes. The RESTful HTTP services reach a broader range of clients; including Wi-Fi aware irrigation smart controllers as well as browser and mobile applications, all while expanding the delivery options by providing data in either JSON or XML formats.

23 Users need an application key (AppKey) in order to have access to CIMIS Data using the Web API. An APPKey is generated after creating an account with CIMIS (using CIMIS website at https://cimis.water.ca.gov/). After generating the APPKey, users have access to the REST Services, which provides hourly and daily data. Examples of Web API inquires can be found by clicking "Online Service Tests" under http://et.water.ca.gov/Rest/Index. http://et.water.ca.gov/Rest/Index
