Climate Zones

This section provides example Thermal Zones and Thermal Moisture Zones background and images.

Thermal Moisture Zones

Below is an example of using the Zones API endpoint to create four-year rolling Thermal Zones and Thermal Moisture Zones Climatologies. A four-year rolling Climatologies means for a representative year, for example 1984, the computation includes the years 1981 though 1984; For 1985 the computation includes the years 1982 though 1985. The images in the videos below are derived from 0.5° x 0.625° MERRA-2 temperature and precipitation data from 1981-2019. The Thermal Zones and Thermal Moisture Zones color palettes follow ASNI/ASHRAE Standard 169-2020.
