Introduction:
L3S_LEO_AM-STAR-v2.80
The NOAA-EUMETSAT Joint Polar System (JPS) builds upon the Initial JPS (IJPS) 
and comprises two Low Earth Orbiting (LEO) satellite sub-systems. NOAA 
contributes first-generation POES (NOAA-7 to -19 with AVHRR GAC onboard; 
from 1981-pr) and second-generation JPSS (NPP and NOAA-20 to -23 with VIIRS 
onboard, from 2011-pr). JPSS satellites fly in the “afternoon” orbit, with a 
nominal local equator crossing times (LEXT) around 1:30am/pm. The EUMETSAT 
contributes two generations of MetOp satellites, flown in mid-morning orbits 
with nominal LEXT around 9:30am/pm: First Generation (FG; with AVHRR FRAC from 
2006-pr) and Second Generation (SG; with METImage onboard, from 2023-on). 
Observations from the NOAA and EUMETSAT satellites cover the diurnal cycle, at 
four reference points approximately separated by 4/8 hours. NOAA processes all 
JPS L1b data with its enterprise SST system, ACSPO, and generates multiple 
global SST products from individual platforms and sensors, in two projections, 
swath L2P and gridded 0.02 degrees lat/lon L3U, 144 file per day for each. 
Following multiple users’ requests for lower volume, higher coverage and 
information content, reconciled and improved SST product, NOAA started 
generating two lines of gridded 0.02º super-collated L3S LEO products, one from 
the NOAA afternoon JPSS (L3S-LEO-PM) and the other from the EUMETSAT mid-morning 
Metop (L3S-LEO-AM) satellites.
