Following the CloudCast Tutorial: CloudCast Stereographic (768, 768) based on reprojection and interpolation .

Here is the domain.

Here we show the associated data.

Mike's Take

The quote "spatial resolution of 928 x 1530 pixels .... where each pixel represents an area of 3×3 km." suggests a simple subset of the non-HRV MSG data.

I assume the longitude subset of 928 rows starts from the northern most row.

(928*3)/111 = 25.081 deg lat giving 81.1257 - 25.081 = 56.0447.

So 81N to 56N, or using valid data lats

78.2998 - 25.081 = 53.2188

or 78N to 53N, which is close to 75N to 50N used by Partio et al. (2024).

20W and 45E

Note: the "full_cropped" CloudCast results has the 768x768 resolution. The coordinates are given in projected coordinates not lon/lat.
