Crop Factors API

getCropFactors

The getCropFactors API provides weather data/factors specific to Ag Industry. With this API, you can retrieve satellite imagery derived weather factors, like Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), and Land Surface Temperature(LSTD & LSTN), and station collected weather data, like air temperature(TMAX & TMIN), and accumulated precipitation(PRCP). Data can be requested for a combination of counties and observation windows.
