Understanding weather satellites’ spatial resolution

Solcast provides more detailed, accurate solar irradiance data through its sophisticated modeling and satellite cloud-tracking capabilities.

What size is the gridded data? What resolution are the forecasts? How far apart in space should I spread my API calls?

Our irradiance data makes use of cloud tracking from geostationary weather satellites with native resolutions of 1 to 2 km’s (1-2 km). In processing the data we reproject to a regular grid with a similar resolution to the native imagery.

Solcast does model irradiance at 90m resolution but as cloud is one of the primary drivers of irradiance variability, most locations will see little variation at finer than satellite resolution.
