Update #1: This is a 2 week reminder for the NDE System Upgrade on August 5th. Please note changes in red text below. GOES-17 ASOS SCP will be excluded in this upgrade, instead GOES-17 CSR/ASR will be included. GOES-16 FLS and Enterprise Cloud, Aerosol, Cryosphere and land products are undergoing further verification.  A future notification will be sent If there are any schedule changes.



Topic: NDE System Upgrade

Date/Time Issued: July 22, 2020 2005 Z

Product(s) or Data Impacted:  All NDE products

Date/Time of Initial Impact:  August 5, 2020 TBD UTC

Date/Time of Expected End: August 5, 2020 TBD UTC

Length of Outage: 2.5 hours



Details/Specifics of Change: 


This installation of NDE release 2.0.24 is planned to occur during back orbits. NDE will not be ingesting, processing or distributing data during installation. No data loss is expected, but there will be a possible backlog of processing when installation is complete.


Algorithm changes include:


Enterprise Cloud, Aerosol, and cryosphere products upgrade from v2.1 to v2.3, land products from v1.2 to v1.4:

The jump in the revision number is due to combined changes of v2.2 and v2.3. The main change is the updated cloud mask look up table, which fixed the issue of overestimated clouds over snow covered land surfaces. IMS/SSMI ancillary data is now used for snow mask. The previously used GFS snow mask is used as a fallback if IMS/SSMI is not available. OISST ancillary data is now optional for processing units that use it. When OISST is not present, GFS data is used as a fallback.


After the upgrade, the product shortname in PDA stays the same, but the version number in the filename will change from v2r1 to v2r3 and land products from v1r2 to v1r4.


New products included in this release are:


GOES-16 Fog/Low Stratus (FLS):

The GOES-16 FLS products include the Fog Depth, Marginal Visual Flight Rule Probability (MVFR), Instrument Flight Rule Probability (IFR), and Low Instrument Flight Rule Probability (LIFR).  The products are in NetCDF4 format and are available in both CONUS and Full Disk coverage.


GOES-17 ASR/CSR:
