- Allow to supply an "extended DEM" (`extended-dem_{domain}_{resolution}.asc`) with a larger extent than the model grid for calculating the sky-view factor and radiation processes.
- Cloudiness parameter `allow_fallback` is more generic and potentially tries several cloudiness calculation methods (e.g. if `method` is `clear_sky_fraction` and no radiation measurements are available, first the `humidity` method is attempted, if also no temperature/humidity measurements are available the `constant` method is used).
- The parameters for the cloudiness method `humidity` can now be specified in the model configuration:
- `pressure_level`: the pressure level for which the calculation should be performed (hPa)
- `saturation_cloud_fraction`: cloud fraction at 100% relative humidity (0-1)
- `e_folding_humidity`: "e-folding relative humidity" (%)
- Related to this, the `humidity` method now uses `pressure_to_altitude()` to convert the prescribed pressure level (700 hPa by default) to an altitude instead of using a hardcoded value of 3000 m, hence introducing small changes in cloudiness values compared to those calculated with earlier openAMUNDSEN versions (1bd686555fb9ce031922625c284d975d67533bd8).
- Add cloudiness method `prescribed`, which interpolates prescribed cloudiness values at the input stations. For this, the input files need to include a variable `cloud_cover` (in %) (adfdf08d579b73f7aa6ddd4182a188e70c57c0b8).
- Cloudiness configuration keys `day_method` and `night_method` have been renamed to `method` and `clear_sky_fraction_night_method` (dbdfd1c07485b3ab7e6a4e347306af459f2b2b4e).
