Update #3: This is a reminder that SNPP/NOAA-20 VIIRS COMP/CCL/CBH/AOD/ADP products(distribution through NCCF) will be operational on May 16, 2023.

Update #2: This is a reminder that the VIIRS COMP, CCL, CBH, AOD, and ADP Products will be Operational (distribution through NCCF) on May 16, 2023

Update #1: The JRR_AOD_BUFR will be included in this release along with the JPSSRR_AOD.

Topic: Declaring VIIRS COMP, CCL, CBH, AOD, and ADP Products Operational in NCCF 

Date/Time Issued: May 14, 2023 1548 UTC

Product(s) or Data Impacted:  SNPP/NOAA-20 VIIRS COMP/CCL/CBH/AOD/ADP

Date/Time of Initial Impact: May 16, 2023

Date/Time of Expected End: May 16, 2023

Length of Outage: N/A

Details/Specifics of Change:

The JPSS Risk Reduction (JRR or JPSSRR) Cloud Optical and Microphysical Properties (COMP), Cloud Cover Layers (CCL), Cloud Base Height (CBH), Aerosol Optical Depth (AOD), and Aerosol Detection Product (ADP) products for SNPP and NOAA-20 and NOAA-21 (pre-beta) are being migrated from NDE on-prem to NESDIS Common Cloud Framework (NCCF). These SNPP and NOAA-20 products are planned to be declared operational in NCCF on May 16, 2023. Since NOAA-21 products will be pre-beta at that time, they will stay in PDA I&T (not distributed to PDA OPS).The PDA short names and product file names will remain the same during this migration. The test products have been available on PDA I&T now. Users can start subscribing to these data products from PDA I&T. The test data product short names are appended with “_TEST”.

Updated products included in this release are:
