SolarAnywhere® non-irradiance weather data is extracted from trusted global reanalysis, numerical weather prediction (NWP) or combination models. Prior to delivery, data is quality controlled by our team and transformed to align with the other SolarAnywhere data you are requesting. Weather-data sources may also be blended to provide seamless coverage across space and time.
When selecting data sources, consistency, resolution and availability are considered. The following tables summarize SolarAnywhere non-irradiance weather-data field coverage.
