  title: 'Climate Engine API v1: climate-engine-pro'
  description: >-
    On-demand geospatial processing of satellite and gridded climate datasets on
    Google Earth Engine. The Climate Engine REST API returns timeseries, map tiles
    (mapid), asynchronous raster exports, zonal statistics, pre-built reports, and
    dataset metadata over point coordinates and GeoJSON feature collections.
    Datasets include Landsat, Sentinel, MODIS, GRIDMET, ERA5, CHIRPS, and many more.
