Astrospheric's primary weather data comes from the Canadian RDPS model. This is a high resolution regional model which offers great accuracy, especially for Astronomy variables like Transparency and Seeing. However, this model does not cover the entire world, so Astrospheric can't provide world-wide data coverage.

Astrospheric's full domain can be seen in this image

Please note that Astrospheric has no influence over the domain covered by the RDPS model. Additionally, there are no plans to use any other model as the primary data source on Astrospheric. If a forecast is requested outside of this domain then an error will be shown in the app. In general, the Astrospheric website is available everywhere, but the apps are only released in countries that have 100% RDPS coverage.

Astrospheric's Cloud Ensemble includes hourly updates from the NBM model, which has an even smaller domain than the RDPS model. The area in white is covered by the NBM.

More information about the Cloud Ensemble can be found here.

When in doubt, attempt to get a forecast at your desired location and check the "Forecast Details" tile at the bottom of the app. The model data will have a green check when available at the location.

The forecast details card will not only show if data is available, it will include the last time Astrospheric processed data from the specified model as well as when the next major update is expected.

Model	Update Frequency
RDPS	6 hours
GFS	6 hours
NAM	6 hours
NBM	1 hour
