The operational algorithm implemented was developed at the University of Miami/Rosenstiel School of Marine and Atmospheric Science (RSMAS). The SOHCS product measures the integrated vertical temperature from the sea surface to the depth of the 26°C isotherm. The Algorithm uses a reduced gravity model to estimate the 20 degree isotherm depth based on objectively analyzed blended sea surface height anomaly fields from operational altimeters (Satellite with ARgos and ALtiKa (SARAL), Jason-1, Jason-2, Cryosat-2, Sentinel-3A, Sentinel-3B, and Sentinel-6A) and Geo-Polar blended SST analyses. The data consists of seven parameters including sea surface height anomaly and its mapping error, depth of the 20° and 26° Celsius isotherm, mixed layer depth, ocean heat content and sea surface temperature. The grid spacing of the data in both latitude and longitude is 0.25°. This product will be used to improve hurricane intensity forecasts and increase lead time warnings for high impact events. It will also provide information about ocean eddies, vertical temperature profiles and sea surface temperature anomalies that may affect coral reefs. onGoing historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact monthly https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:NESDIS-OHC Preview graphic PNG 0139262 0139313 0139314 0139388 0139389 0139390 0139402 0139403 0139404 0139405 0139406 0139407 0139408 0139409 0139410 0139415 0139416 0139500 0139501 0139502 0139503 0139504 0139505 0139506 0139507 0139508 0139509 0139510 0139511 0139512 0139513 0139517 0139518 0139519 0139520 0139521 0139522 0139523 0139524 0139525 0140097 0141305 0144930 0145951 0149717 0152451 0155212 0156208 0156473 0156679 0156871 0157091 0157686 0159641 0161270 0162255 0162479 0163176 0163899 0164664 0165704 0166921 0167750 0168911 0169568 0170398 0170929 0172025 0173042 0173534 0174253 0175033 0175836 0176561 0177857 0181741 0184050 0184419 0185857 0187198 0188316 0189617 0191088 0192838 0201580 0204024 0206291 0207626 0208291 0209033 0209153 0209375 0211877 0212540 0212686 0215981 0219915 0220286 0221624 0222655 0223900 0225443 0226137 0228084 0232181 0235389 0238643 0239784 0240831 0241606 0242736 0243816 0244851 0247170 0249139 0251138 0253182 0253689 0255161 0257324 0259415 0261927 0268352 0275221 0276214 0276520 0276897 0277456 0277847 0278933 0279745 0281217 0282404 0283582 0285804 0285805 0286805 0288559 0289869 0290793 0292303 0293503 0294677 0295908 0296972 0297749 0298650 0299598 0300358 0301510 0302256 0303149 0304025 0304848 0305858 0306832 0307629 0308468 0309212 0310382 0311289 0312218 0313017 0313889 0314672 NCEI ACCESSION NUMBER 2026-05-03 publication FLUX - HEAT SEA SURFACE TEMPERATURE SEA SURFACE TOPOGRAPHY THERMOCLINE DEPTH theme NODC DATA TYPES THESAURUS AltiKa AVHRR GOES Imager JAMI Poseidon-3 altimeter Poseidon-4 Radar Altimeter satellite sensor - altimeter SIRAL SRAL VIIRS instrument NODC INSTRUMENT TYPES THESAURUS satellite data theme NODC OBSERVATION TYPES THESAURUS CryoSat-2 GOES-13 GOES-15 JASON-1 Jason-2 Jason-3 Meteosat-10 (MSG3, Third METEOSAT Second Generation Satellite) MetOp-B (Meteorological Operational satellite-B) MTSAT-2 (Himawari 7) SARAL (Satellite with ARgos and ALtiKa) Sentinel-3A Sentinel-3B Sentinel-6A SNPP platform NODC PLATFORM NAMES THESAURUS NOAA National Environmental Satellite, Data, and Information Service NOAA Office of Satellite and Product Operations dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA National Environmental Satellite, Data, and Information Service NOAA Office of Satellite and Product Operations dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Bay of Biscay (Golfe de Gascogne) Bay of Fundy Bering Sea Bismarck Sea Bristol Channel Caribbean Sea Coastal Waters of Southeast Alaska and British Columbia Coral Sea Davis Strait East China Sea (Tung Hai) English Channel (La Manche) Great Australian Bight Gulf of Alaska Gulf of America Gulf of California Gulf of Guinea Gulf of Mexico Gulf of St. Lawrence Gulf of Thailand Hudson Bay Indian Ocean Inner Seas off the West Coast of Scotland Irish Sea and St. George's Channel Japan Sea Mediterranean Sea North Atlantic Ocean North Pacific Ocean North Sea Philippine Sea Sea of Okhotsk Seto Naikai (Inland Sea) Solomon Sea South Atlantic Ocean South China Sea (Nan Hai) South Pacific Ocean Southern Ocean Tasman Sea Yellow Sea (Hwang Hai) place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS > National Environmental Satellite, Data, and Information Services, NOAA, U.S. Department of Commerce DOC/NOAA/NESDIS/OSPO > Office of Satellite and Product Operations, NESDIS, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 23 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

NOAA National Centers for Environmental Information custodian AltiKa AltiKa Ka-band Altimeter AltiKa is a Ka-band altimeter (35 GHz) developed by CNES (Space Agency of France) on-board the Satellite with ARgos and ALtiKa (SARAL). It is the first space-born ocean surface topography instrument using such a high frequency. The use of the Ka-band frequency will supply more accurate measurements (improvement of the spatial and vertical resolution of the ocean surface topography observations), enabling a better observation of ice, coastal areas, continental water bodies as well as wind and waves height. SARAL is a French and Indian collaborative mission to measure sea surface height using the Ka-band AltiKa altimeter and was launched on February 25, 2013.

Source: Glossary of GIS and Remote Sensing Terms, University of Vermont. (http://fwie.fw.vt.edu/tws-gis/glossary.htm; last accessed on 09/22/2004). Specifically, this instrument type is to be used to represent AVHRR/1: "There are two series of AVHRR instruments. Built by ITT Aerospace/Optical Division in the mid 1970s, the AVHRR/1 is a four-channel, filter-wheel spectrometer/radiometer (Appendix) while the AVHRR/2, built in the early 1980s, is identical except for the addition of Channel 5." See https://www.ngdc.noaa.gov/ecosys/cdroms/AVHRR97_d1/avhrr3.htm GOES Imager GOES Imager Geostationary Operational Environmental Satellite Imager The GOES I-M Imager is a five channel (one visible, four infrared) imaging radiometer designed to sense radiant and solar reflected energy from sampled areas of the earth. By means of a servo driven, two-axis gimbaled mirror scanning system in conjunction with a Cassegrain telescope, the Imager's multispectral channels can simultaneously sweep an 8-kilometer (5 statute mile) north-to-south swath along an east-to-west/west-to-east path, at a rate of 20 degrees (optical) east-west per second. This translates into being able to scan a 3000 by 3000 km (1864 by 1864 miles) "box" centered over the United States in just 41 seconds. The actual scanning sequence takes places by sweeping in an East-West direction, stepping in the North-South direction, than sweeping back in a West-East direction, stepping North-South, sweeping East-West, and so on. The Imager consists of electronics, power supply, and sensor modules. The sensor module containing the telescope, scan assembly, and detectors, is mounted on a baseplate outside the main structure of the spacecraft, together with shields and louvers for thermal control. The electronics module provides redundant circuitry and performs command, control, and signal processing functions; it also serves as a structure for mounting and interconnecting the electronic boards for proper heat dissipation. The power supply module contains the converters, fuses, and power control for interfacing with the spacecraft electrical power subsystem. The electronics and power supply modules are mounted inside the spacecraft on the internal equipment panel.

The JAMI instrument has been designed and developed by Raytheon SBRS (Santa Barbara Remote Sensing) of Goleta, CA under contract to Space Systems/Loral and was carried on Japanese MTSAT-1R satellite (a replacement for MTSAT-1). This instrument has a visible channel at 0.55-0.90 µm; three Thermal Infra Red (TIR) Imaging channels (3.5-4.0 µm, 10.3-11.3 µm and 11.5-12.5 µm) as well as an infrared channel at 6.5-7.0 µm. Radiation in JAMI sensor is collected by a telescope with an aperture of 311 mm and focal length of 895 mm and focussed onto photovoltaic mercury cadmium telluride infrared detectors. The size of the detectors is 50 µm square, giving an angular resolution of 56 µrad and hence a linear resolution of 2 km at nadir. The nadir sampling interval, and effective resolution is 4 km. MTSAT-1R that was launched in 2005 at 140 deg. East is operational since mid-2005.

The Poseidon-3 altimeter is a compact, low-power, low-mass instrument offering a high degree of reliability. Poseidon-3 is a radar altimeter that emits pulses at two frequencies (13.6 and 5.3 GHz; the second frequency is used to determine the electron content in the atmosphere) and analyzes the return signal reflected by the surface. The signal round-trip time is estimated very precisely to calculate the range, after applying the necessary corrections.

The four mission participants are: National Oceanic and Atmospheric Administration (US NOAA), National Aeronautics and Space Administration (US NASA), Centre National d'Etudes Spatiales (FRANCE CNES), and European Meteorological Satellite Organisation (EU EUMETSAT). JASON-2 was built under direction from CNES. After launch by NASA, CNES and NASA transferred operation and control of the JASON-2 platform to NOAA. The Jason-2 satellite was launched in June 20, 2008. Submitted to ICES on 2014-06-04. Confirmed by NOAA on 2018-08-08. After more than 11 years in orbit and well beyond its three- to five-year mission baseline, the Ocean Surface Topography Mission (OSTM) on Jason-2 permanently ceased acquisition of scientific data at 06:48 UTC on 1 October 2019 due to aging-related issues onboard the spacecraft. Jason-3 Description: Altimetry satellite; follow-on of the TOPEX-Poseidon satellite and Jason-1 and Jason-2 satellite missions Country *: FR FRA 250 ISO 3166-2:FR (NODC ATDB=79) Platform Class *: 65-Orbiting satellite Operations/Responsible organization: Centre National d'Etudes Spatiales (CNES) Previous Name: N/A Commissioned Date: (2015-03) Current Length (m): Height: app. 4 meters Notes +: Jason-3 is the fourth mission in U.S.-European series of satellite missions that measure the height of the ocean surface. Scheduled to launch in 2015, the mission will extend the time series of ocean surface topography measurements (the hills and valleys of the ocean surface) begun by the TOPEX/Poseidon satellite mission in 1992 and continuing through the currently operating Jason-1 (launched in 2001) and OSTM/Jason-2 (launched in 2008) missions. These measurements provide scientists with critical information about circulation patterns in the ocean and about both global and regional changes in sea level and the climate implications of a warming world. The primary instrument on Jason-3 is a radar altimeter. The altimeter will measure sea-level variations over the global ocean with very high accuracy (as 1.3 inches or 3.3 centimeters, with a goal of achieving 1 inch or 2.5 centimeters). Continual, long-term, reliable data of changes in ocean surface topography will be generated and will be used by scientists and operational agencies (NOAA, European weather agencies, marine operators, etc.) for scientific research and operational oceanography for the benefit of society. TOPEX/Poseidon and Jason-1 were cooperative missions between NASA and the French space agency, CNES. Additional partners in the Jason-2 mission included NOAA and Eumetsat. Jason-3 continues the international cooperation, with NOAA and Eumetsat leading the efforts, along with partners NASA and CNES. Info Source: https://sealevel.jpl.nasa.gov/missions/jason3/ http://smsc.cnes.fr/JASON3/GP_satellite.htm The Jason-3 satellite was launched on 17 January 2016 from Vandenberg Air Force Base in California, on a SpaceX Falcon 9 launcher, and was placed into the same orbit as OSTM/Jason-2, at an altitude of 1,336 kilometers with an inclination of 66 degrees, to provide virtually blanket coverage of all ice-free ocean surfaces.

Mass: 4,650kg (at launch) Electrical power: 3,410 W Design life: 10 years Description The MTSAT-2 is a multi-functional satellite that carries out both an aviation mission, including air traffic control, and a meteorological mission. The purpose of the aviation mission is to improve traffic congestion and safety in the Asia-Pacific region with a next-generation global-scale air traffic safety system made up of communications, navigation, tracking and air traffic control. The purpose of the meteorological mission is to capture, collect and deliver meteorological images and/or data, inheriting and expanding the mission of the GMS-5 which is also currently in service. Multi-functional Transport Satellites (MTSAT) are a series of geostationary weather satellites operated by the Japan Meteorological Agency (JMA). MTSAT carries an aeronautical mission to assist air navigation, plus a meteorological mission to provide imagery over the Asia-Pacific region for the hemisphere centered on 140 East. The meteorological mission includes an imager giving nominal hourly full Earth disk images in five spectral bands (one visible, four infrared). MTSAT are spin stabilized satellites. With this system images are built up by scanning with a mirror that is tilted in small successive steps from the north pole to south pole at a rate such that on each rotation of the satellite an adjacent strip of the Earth is scanned. It takes about 25 minutes to scan the full Earth's disk. This builds a picture 10,000 pixels for the visible images (1.25 km resolution) and 2,500 pixels (4 km resolution) for the infrared images. The MTSAT-2 (also known as Himawari 7) and its radiometer (MTSAT-2 Imager) was successfully launched on 18 February 2006. Submitted to ICES on 2018-01-03.

Suomi, University of Wisconsin meteorologist, widely recognized as the "Father of Satellite Meteorology." Suomi NPP is the first next generation polar-orbiting satellite in the JPSS series, and is considered the bridge between NOAA's legacy polar satellite fleet, NASA's Earth observing missions and JPSS constellation. Launched in October 2011, Suomi NPP boasts five state-of-the-art instruments: (1) VIIRS, (2) CrIS, (3) ATMS, (4) OMPS, and (5) CERES FM5— which will be the similar instruments carried on JPSS-1. It has design life of five years and was launched with a Delta-II Mission Launch Vehicle from Vandenberg Air Force Base, California.
