GOES All Sky LAP TPW and CIRA Merged TPW Cloud Mask Differences

At 22 UTC on 6 May 2019, the All Sky LAP and CIRA Merged TPW Data type products show differences in the cloud mask.  A shallow Cu field over NC / SC is indicated in GOES visible imagery,.  The data type masks of the two products (blue = clear; yellow / gray = clouds) show some clouds in the All Sky LAP mask, while the CIRA Merged TPW mask does not have these Cu detected.  This is likely due to the lower resolution (~ 15 km) of the GOES-16 TPW data used in Merged TPW versus the All Sky LAP resolution.

GOES-R TPW has a nominal resolution of 10 km.
