Hello,

in [the documentation](https://confluence.ecmwf.int/display/CKB/CAMS+Regional%3A+European+air+quality+analysis+and+forecast+data+documentation), there is [a link to download](https://confluence.ecmwf.int/download/attachments/384140005/LSM_REGIONAL_CAMS_01.nc?version=1&modificationDate=1705330702613&api=v2) the land-sea mask, but it’s 25W/30N/45E/70N (old domain), rather than 72N.

Is there a land-sea mask for the new domain somewhere?

Thanks
