        abstract:  This dataset contains data from the NOAA NCEI Surface Underway Marine Database (SUMD), formerly known as the NCEI Thermosalinograph (TSG) Database. The database was originally developed to facilitate understanding and access to a set of quality controlled in-situ sea surface temperature (SST) and salinity (SSS) measurements collected by thermosalinographs (TSG) in 2016. The database was later expanded to include surface underway non-TSG data, such as meteorological data from the vessel-mounted meteorological packages and data from Unmanned Surface vehicles, such as Saildrones and Wave Gliders. Data were surface in situ underway data collected by thermosalinographs (TSG), meteorological packages and other sensors from 1986-05-23 to 1986-07-22 from PMEL. These data are from multiple data assembly centers, including the Center for Ocean-Atmospheric Prediction Studies (COAPS; TSG data from the Shipboard Automated Meteorological and Oceanographic System (SAMOS)), Institut français de recherche pour l'exploitation de la mer (IFREMER; English: French Research Institute for Exploitation of the Sea; TSG data from The Global Ocean Surface Underway Data (GOSUD)), Atlantic Oceanographic & Meteorological Laboratory (AOML-TSG data) and NOAA National Centers for Environmental Information (NCEI). When duplicate data were found with different resolution, the data with the highest sampling resolution were selected. All data were converted to common netCDF format, following the Climate and Forecast (CF) and Attribute Convention for Data Discovery (ACDD) conventions and following the NCEI netCDF2.0-trajectory feature type. All data were processed using the same 11-step quality control procedures and criteria and flagged using a two-level flag system to provide a well-organized, uniformly quality-controlled high resolution surface underway dataset for the user community.
        purpose:  To provide a well-organized, uniformly quality-controlled surface underway data database.
        credit:  This project was funded by NOAA STAR and NCEI.

                code:  carbon dioxide (CO2) gas analyzer
            type:  carbon dioxide (CO2) gas analyzer
            description:  measures gaseous carbon dioxide Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.

                code:  PAR Sensor
            type:  PAR Sensor
            description:  Photosynthetically Active Radiation Sensor The PAR sensor measures global solar radiation from 400 to 700 nm, which approximates the spectral band active in photosynthesis. The response of the instrument falls sharply to zero on either side of this band, and between 400 and 670 nm it increases monotonically from about 50% to 100%. There is no protective glass dome over the receiving surface. Irradiance from the sun passes through a small white visible bandpass filter/diffuser in the shape of a horizontal disk at the top of the instrument. Within the instrument radiation is directed through a series of colored glass filters and onto a silicon photodiode detector. The factory-supplied calibration converts the signal from the detector to a flux of photons in micro-mole (of photons) s-1 m-2. (One micro-mole equals 6.022 E17 photons.) For the solar spectrum, these units may be converted to watts per square meter by dividing by 4.6. (http://www.srrb.noaa.gov/instrument/par.htm)
