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. PDA short names are listed in the Table below. Note that the legacy format VIIRS ACSPO files (PDA Short Name: ACSPO_SST) are meant for internal use only and plans are in place to retire these legacy products in all future releases of ACSPO. In addition, BUFR files are also included in this update and have been listed.

List of Scientific Changes:

A. Modified scripts and codes to add option for running J02 for V8Pro algorithm, added required tables and ancillary files for J02.

B. Replaced old RT tables and triangular slit internal bandpass models with new RT tables and new higher-fidelity models.

C. Updated soft-calibration for aerosol channel of S-NPP retrievals and make the averaged AI at Equatorial Pacific equal to zero. Set soft-calibrations for both N20 and J02 to be zero for later adjustments.

Please note: This upgrade will not be performed during Critical Weather Day (CWD).
