        abstract:  This dataset includes chemical, meteorological, physical time series data collected from TAO125W_0N in the Equatorial Pacific Ocean from 2004-05-08 to 2022-03-15. These data include air-sea difference of partial pressure of carbon dioxide (pCO2), barometric pressure, oxygen, pCO2 in atmosphere, pCO2 in water, sea surface salinity, sea surface temperature and pH on total scale. The Moored Autonomous pCO2 [MAPCO2 (trademark of NOAA)] instruments used to collect these data include Bubble type equilibrator for autonomous carbon dioxide (CO2) measurement, Carbon dioxide (CO2) gas analyzer, Humidity Sensor, and oxygen meter. The Global CO2 Time-series and Moorings Project involves international groups from 18 countries who have mounted sensors on moored buoys to provide high resolution time-series measurements of atmospheric boundary layer and surface ocean CO2 partial pressure (pCO2). The CO2 Time-series and Moorings Project is coordinated by International Ocean Carbon Coordination Project (IOCCP).
        purpose:  This dataset is available to the public for a wide variety of uses including scientific research and analysis.

                code:  bubble type equilibrator for autonomous carbon dioxide (CO2) measurement
            type:  bubble type equilibrator for autonomous carbon dioxide (CO2) measurement
            description:  This type of equilibrators are often used on buoys. Developed by Pacific Marine Environmental Laboratory and Monterey Bay Aquarium Research Institute, the h-shaped bubble equilibrator does not require a water pump to spray water from the top. see Takahashi 1961 for more information.

                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.
