Dear All,
I just want to give support to Charles Paxson's suggestion.
We would need at least the cloud_binary_mask and the aerosol_binary_mask, probably also dust_binary_mask, for the Nowcasting SAF products.
Best regards,
Sara H?rnquist

Subject: [CF-metadata] GOES-R generated binary mask products under proposal
Dear CF Metadata Users Group,
Through observations and analysis, GOES-R weather products produce binary masks for: aerosols, smoke, dust and clouds. No coordinate value is warranted (i.e. CF Metadata standard surface_snow_binary_mask) for any of these four proposed quantities, since a complex set of tests for each case, such as using brightness temperatures, are used to derive signatures of the four atmospheric constituents. The proposed masks are analogous and defined in a similar way as the CF Metadata standard names: land_binary_mask and sunlit_binary_mask.
aerosol_binary_mask: X_binary_mask has 1 where condition X is met, 0 elsewhere. 1 = aerosols present, 0 = aerosols absent
smoke_binary_mask: X_binary_mask has 1 where condition X is met, 0 elsewhere. 1 = smoke present, 0 = smoke absent
dust_binary_mask: X_binary_mask has 1 where condition X is met, 0 elsewhere. 1 = dust present, 0 = dust absent
cloud_binary_mask: X_binary_mask has 1 where condition X is met, 0 elsewhere. 1 = cloud present, 0 = cloud absent (clear)
Please accept these four mask names for inclusion into the CF Metadata standard.
Sincerely,
Charles Paxson
