Towards a daily Gridded Super-Collated SST Product from Low Earth Orbit Satellites (L3S-LEO-D) at NOAA

Presented at the GHRSST XXIII international science team meeting, 27 June-1 July 2022, online and in-person (Barcelona). #GHRSST23

Short abstract
NOAA provides 0.02° gridded super-collated (L3S) SST products from low earth orbit (LEO) satellites, produced using its Advanced Clear-Sky Processor for Ocean (ACSPO) enterprise SST system. The L3S-LEO family comprises two lines: PM (from afternoon satellites; currently using 2 VIIRS instruments onboard NPP/N20) and AM (from mid-morning satellites; currently using 2-3 AVHRR FRAC instruments onboard Metop-A/B/C). Both L3S-LEO PM/AM products are reported twice daily, one for day and one for night, resulting in four files per day, sampling the diurnal cycle at approximately 1:30am/pm (LEO-PM) and 9:30am/pm (LEO-AM) local times. Complete archives of ACSPO L3S-LEO PM/AM products are available at PO.DAAC and CoastWatch, with new data added in near-real-time.
