The experiment was conducted approximately 300 km offshore of San Francisco, during a pilot campaign that spanned two weeks in October 2021, and two intensive operating periods in Fall 2022 and Spring 2023. S-MODE aims to understand how ocean dynamics acting on short spatial scales influence the vertical exchange of physical and biological variables in the ocean. The Underway CTD system contains a standard UCDT probe measuring conductivity, temperature, and pressure, as well as an augmented EcoCDT probe that concurrently measures both hydrographic and bio-optical data including conductivity, temperature, pressure, dissolved oxygen concentration, chlorophyll-fluorescence, and particulate backscatter at two different wavelengths. The level 2 data herein combines measurements from both the UCDT and EcoCDT into a single dataset, where for each variable, all profiles are binned onto a 5m vertical grid and merged into a 2-D matrix. Additional computed variables include backscatter baseline signal and backscatter spike signal. Data are available in netCDF format.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search?q=rssmif16d", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/rssmif16d__7/browse/2008/f16_ssmis_20080101v7_A_CW.png", "format": "PNG", "mediaType": "image/png"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/rssmif16d__7/docs/SSMI_Data_in_NetCDF.docx", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "http://dx.doi.org/10.5067/MEASURES/SSMI-SSMIS/DATA301", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/rssmif16d__7/docs/ssmi_ssmis_dataset.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/rssmif16d__7/docs/rain.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/rssmif16d__7/docs/Hilburn_V7_Poster_AMS_SatMet_2010_Annapolis.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/rssmif16d__7/docs/ssmi.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/rssmif16d__7/docs/AMSR_Ocean_Algorithm_Version_2_Supplement_1.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/rssmif16d__7/docs/2012_Wentz_011012_Version-7_SSMI_Calibration.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/rssmif16d__7/docs/AMSR_Ocean_Algorithm_Version_2.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/rssmif16d__7/software/ReadNetCDF.c", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/rssmif16d__7/browse/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.nsstc.nasa.gov/home/about-ghrc/citing-ghrc-daac-data", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C1996546500-GHRC_DAAC.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "10.5067/SMODE-RVECT", "keyword": ["earth-science-ocean-chemistry-oceans-oxygen", "earth-science-ocean-optics-oceans-fluorescence", "earth-science-ocean-optics-oceans-scattering", "earth-science-ocean-temperature-oceans-ocean-temperature-profiles", "earth-science-salinity-density-oceans", "earth-science-salinity-density-oceans-conductivity", "earth-science-salinity-density-oceans-ocean-salinity-ocean-salinity-profiles", "earth-science-salinity-density-oceans-salinity"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/JPL/PODAAC"}, "spatial": "[\"CARTESIAN\",[{\"NorthBoundingCoordinate\":38.1,\"WestBoundingCoordinate\":-125.4,\"EastBoundingCoordinate\":-122.9,\"SouthBoundingCoordinate\":36.3}]]", "temporal": "2021-08-01/2023-05-31", "theme": ["Earth Science"], "title": "S-MODE Shipboard uCTD and EcoCTD Measurements Version 1"}
