2. Global SST product examples
• OSTIA Near real time foundation SSTs (the
temperature from which the diurnal cycle
develops)
• OSTIA Reprocessed foundation SSTs covering
late-1981 to 2019
• Daily average skin SSTs at 20 cm depth from late-
1981 to 2019 from the European Space Agency
Climate Change Initiative (ESA CCI) and the
Copernicus Climate Change Service (C3S)
Hourly average skin SSTs
produced daily in near
real time (left: differences
between the skin and
foundation SST)
Daily ensemble of
global level 4 analyses
produced around the
world

3. • Near real time, daily mean (night-time), L3S and L4 foundation SSTs (the temperature free of diurnal cycle)
at HR (high-res., 1/16°) and UHR (ultra-high res., 1/100°) spatial resolution from 2008 up to real time
• Reprocessed, daily mean (night-time), L4 foundation SSTs from 1982 to 2019 at 0.05° based on ESA CCI-
and C3S upstream L3C SST data
Mediterranean and Black Sea SST product examples

Diurnal (hourly mean) sub-
skin SSTs produced daily in

6. European North West shelf/Iberia Biscay Irish Seas SST product example
Level 4 analysis, covering the European North
West shelf/Iberia Biscay Irish Seas (0.02° x 0.02°)
Both NRT and REP products result from the merging and
interpolation of various satellite SST level 2 data after inter-
calibration and bias correction
