Update #2: This is a reminder of the NDE System Upgrade scheduled on March 3, 2022 at 1600 UTC. Please note: The VIIRS ACSPO 2.8 products will not be released for production in this release due to the need for additional testing and checks. These products will be released in a later NDE release. The VIIRS v2.8 ACSPO SSTs will remain available for testing on the NDE I&T and PDA I&T test environments for existing I&T user groups.
Update #1: This notification serves as a two-week reminder of the NDE System Upgrade scheduled on March 3, 2022.

3. Improved analysis of Sub-Tropical (ST) designated cyclones
4. Improved analysis of Extratropical Transition (ET) events
5. Include estimates of TC surface wind radii (34/50/64 knot wind radii, in nmi.)
6. Implement ADTv9.0 on NDE
7. ADTv9.0 will only generate products by ATCF bulletins.
8. ADTv9.0 will not include DMSP satellites.
The ADT FIX product shortname will be changed:

Operational Update of the S-NPP and NOAA20 VIIRS ACSPO SST on NDE:
Impact on users: YES
We will update S-NPP and NOAA20 VIIRS ACSPO SST Products with ACSPO v2.8. Upgrades in ACSPO v2.80 from STAR to include (1) ACSPO thermal fronts (for both LEO, GEO and super-collated L3S); (2) reduced high-latitude biases; (3) reduced L2P file size by a factor of ~3 (as brightness temperatures are no longer included); (4) improved cloud screening; 5) added support of J2/N21 and Meteosat Third Generation platforms. Product generation will remain on the NDE (on-prem NDE) and product distribution will remain on the PDA. The VIIRS v2.8 ACSPO SSTs will be available for testing on the NDE I&T and PDA I&T test environments for existing I&T user groups from January 31 - March 2nd. If you are not an I&T user, contact the PAL (Sheekela.Baker-Yeboah@noaa.gov) for additional help with sample V2.8 granules. We plan to replace the ACSPO v2.61 VIIRS ACSPO SST products on the PDA with the ACSPO v2.8 VIIRS ACSPO SST products by March 3rd. PDA short names are listed in the Table below.
Please make the required updates to your processing/operations by March 2, 2022. Let us know if you have any questions.
Please note: This upgrade will not be performed during Critical Weather Day (CWD).
