NOAA CoastWatch has added the operational SST L3S Day/Night AM/PM product suite to HTTPS distribution:

https://coastwatch.noaa.gov/data/pub0053/coastwatch/sst/l3s/

The morning/afternoon orbit, day and night SST L3S products are now produced by the Office of Satellite and Product Operations. Products are mirrored daily and have increased reliability. Fifteen (15) days of operational near real-time data are available in this directory. Note, the L3S Daily product is not currently produced by OSPO. A transition from research (STAR) to operational (OSPO) processing is expected to begin at the end of 2024.

At present the L3S produced within OSPO uses ACSPO version 2.8x. Sea surface temperature data differences with the STAR produced L3S (ACSPO v 2.8x+) are considered negligible.

The sea surface height team in NOAA’s Laboratory for Satellite Altimetry developed two experimental mesoscale eddy products:

Multiparameter Eddy Significance Index (MESI)
MUltiparameter NRT System for Tracking Eddies Retroactively (MUNSTER)

MESI serves as a first look indicator of the potential impact a given mesoscale eddy may have on upper ocean dynamics, with potential implications for nutrient cycling, mixed layer dynamics, and fisheries. The MUNSTER suite of eddy tracking products provides analyzed mesoscale eddy properties, contours, and trajectories based on NOAA RADS gridded altimetry and includes analysis calculated from altimetry, SST, SSS, and chlorophyll-a from ocean color. MUNSTER is a threshold free product suite, with no limitations imposed on eddy lifetime or amplitude, and includes a wide variety of analyzed variables, including MESI. The MUNSTER mesoscale eddy product suite has a wide variety of applications across oceanography, including coral reef resilience monitoring, studies of air-sea interactions, harmful algal blooms, coral reef larva dispersion, and fisheries management, among many others.

NOAA CoastWatch has processed a limited number of products that are available for comment through September 30, 2024. Collected feedback and additional enhancements (metadata) will be implemented prior to making a data asset spanning August 2019 to present. Please visit https://coastwatch.noaa.gov/cwn/products/experimental-eddy-products.html to explore these data products and submit feedback to coastwatch.info@noaa.gov.

Sea surface temperature processing of ACSPO FRAC L2P/L3U and L3S products has been suspended due to ongoing maintenance beginning August 12, 2024. We are hopeful processing is restored today (August 15, 2024) and expect L2P/L3U products to catch-up within 10 hours and L3S in about 24 hours. The global 2km low earth orbit (LEO) Level-3 Supercollated (L3S) product is expected to become operational (24hour-by-7day support) within NOAA NESDIS later this month.

The Ocean Heat Content product produced by the Office of Satellite Products and Operations has been updated for cloud processing resulting in a change to the filename and underlying metadata.

The filename changed:

from 
ohc_\w{2}QG\d{1}_\d{4}_\d{3}\.nc$ 
to 
OHC-<LOC>QG3_<v1r0>_blend_<sYYYYMMDDHHMMSSS>_<eYYYYMMDDHHMMSSS>_<cYYYYMMDDHHMMSSS>.nc

The convention for specifying the start and stop time is different. The start and stop times used to specify a span of 24 hours but now to reflect the entire timespan of the altimetry input used to produce the product the start and stop times now span 14 days.

                       Old                     New
Start time      2024-01-17T00:00:00Z    2024-01-09T00:00:00Z
Stop time       2024-01-18T00:00:00Z    2024-01-22T23:59:59Z

Note that the single day of the old convention corresponds to the final day of the 14-day range of the new convention. NOAA CoastWatch webpages and distribution points will be updated to reflect these changes.

The NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) L3S-LEO-PM and L3S-LEO-DY products will be updated from ACSPO v2.80 to ACSPO v2.81 on October 2, 2023.

The updates from V2.80 are:

N21 VIIRS has been added to L3S-LEO-PM. Now it includes 3 VIIRS sensors from NPP, N20 and N21
The L3S-LEO-PM daytime SST has been de-trended to fix a ~0.15 K negative drift in bias over the past decade or so.
Aqua MODIS SST has been included in L3S-LEO-PM. This update extends the L3S-LEO-PM dataset back to 4 Jul 2002 when the first Aqua SST became available. Due to current drift of the Aqua satellite orbit, Aqua SST is not included in L3S-LEO-PM after 31 Dec 2022.
Aqua and Terra MODIS SSTs have been both included in L3S-LEO-DY. This extends the L3S-LEO-DY dataset back to 24 Feb 2000, when the first Terra SST became available. Due to current drift of the Terra satellite orbit, Terra SST is not included in L3S-LEO-DY after Dec 31 2021.

Routine users will need to plan for the change in filenames where the version number will change from v2.80 to v2.81.

For example:

from: 20230911120000-STAR-L3S_GHRSST-SSTsubskin-LEO_PM_N-ACSPO_V2.80-v02.0-fv01.0.nc
to: 20230911120000-STAR-L3S_GHRSST-SSTsubskin-LEO_PM_N-ACSPO_V2.81-v02.0-fv01.0nc

Currently the V2.81 NRT data are pushed to

Anthropogenic emissions of carbon dioxide (CO2) have increased dramatically since the Industrial Revolution. The oceans absorb approximately one third of this carbon dioxide. When CO2 is absorbed by seawater, chemical reactions occur that reduce the pH (increase the acidity). "Ocean acidification" refers to this lowering of ocean pH. Among other issues, ocean acidification makes it difficult for calcifying animals, such as corals and shellfish, to grow and thrive. This occurs because sea water at a lower pH has a reduced availability of the carbonate minerals (calcite, aragonite and high-magnesium calcites) these animals use to construct their shells and skeletons.

Coral reefs provide immense ecological and economic benefits to the Caribbean region.

In collaboration with the NOAA Atlantic Oceanographic and Meteorological Laboratory's Ocean Chemistry and Ecosystems Division and NOAA Coral Reef Watch, the Caribbean/Gulf of America node of CoastWatch produces an ocean acidification product suite for the greater Caribbean region to track changes in the surface ocean that can be used as an important tool in coral reef research and management.

The suite of ocean acidification products produced by the CoastWatch Caribbean/Gulf of America node and Coral Reef Watch. Products include SST, SSS, pCO2a, pCO2w, Alk, pH, Ωarg and Ωcal. Source: CoastWatch Caribbean/Gulf of America node.
