Administrative: Update #1: Implementation of GOES-16 and GOES-17 ABI Enterprise Cloud Mask Level 2+ Algorithm on or about November 29, 2021, Issued: November 17, 2021 1640 UTC

Update #1:  The estimated date of implementation is now on or about November 29, 2021 at TBD UTC

Topic: Implementation of GOES-16 and GOES-17 ABI Enterprise Cloud Mask Level 2+ Algorithm

Date/Time Issued: November 17, 2021 1640 UTC

Product(s) or Data Impacted: GOES-16 and GOES-17 Cloud Mask Products

Date/Time of Initial Impact:  On or about November 29, 2021 TBD UTC

Details/Specifics of Change: 

The GOES-16 and GOES-17 ABI Enterprise Cloud Mask algorithm will replace the baseline cloud mask algorithm on or about November 29, 2021 at TBD UTC. Users of the current cloud mask product will not see any interruptions to data delivery but the resultant product files will change to reflect the output of the enterprise algorithm. The Binary Cloud Mask (BCM) parameter in the current Cloud Mask will remain, however additional parameters in the netCDF4 product include:

ACM = 4 Level Cloud Mask

Cloud_robabilities = Cloud Probability

The Enterprise Cloud Mask (ECM) algorithm was developed by the Algorithm Working Group (AWG) with the capability to process multi-spectral data from multiple sources. This means that the science code can ingest data from various platforms (GOES-R ABI, VIIRS, etc.) and produce sensor-specific products using a similar “Enterprise” approach. The ECM algorithm uses a naive Bayesian approach for cloud detection; an approach that brings it into line with products generated by other NOAA instruments.
