These data have not been Quality Control (QC). This was the first of three missions funded by NOAA Office of Oceanic and Atmospheric Research (OAR)/CPO/GOMO and NOAA/OMAO as a pilot study for the Tropical Pacific Observing System (TPOS)-2020 project. The PMEL TPOS 2017 Mission (aka Mission 1) had two Gen-4 Saildrones, each with a full atmospheric and ocean core sensor suite, an Acoustic Doppler Current Profiler (ADCP), and an ASVCO2 carbon flux and pH system. The two drones were deployed out of Alameda, CA on September 1, 2017, for a mission in the equatorial Pacific. After sailing near the CCE1 mooring off coastal California, the drones proceeded to the area near 10N, 125W. They remained in the area from October 18 - November 13, 2017, to participate in the Salinity Processes in the Upper Ocean Regional Study (SPURS)-2 field study, which included side-by-side data acquisition with a Woods Hole Oceanographic Institution (WHOI) buoy, and the R/V REVELLE. When SPURS-2 ended, the drones sailed south on either side of 125W, stopping for comparisons against Tropical Atmosphere/Ocean (TAO) moorings at 8N, 5N, and 2N. After crossing the equator, the drones returned to California. SD-1006 was recovered from San Francisco Bay on May 18, 2018.

NOAA National Centers for Environmental Information custodian anemometer anemometer measures wind speed An anemometer is an instrument that measures wind speed. Note that an aerovane (insttypes_id 175) is an anemometer which has a tail and a propeller to measure the speed and direction of the wind. barometer barometer Barometers are instruments for measuring atmospheric pressure; two types include mercury barometers and aneroid barometers. clock clock An instrument for measuring time. CTD CTD Conductivity-Temperature-Depth probe fluorometer fluorometer fluorometer GPSP GPSP Global Positioning System space Payload The GPSP uses the Global Positioning System (GPS) to determine the satellite's position by triangulation, in the same way that GPS fixes are obtained on Earth. At least three GPS satellites determine a mobile object's (in this case the satellite's) exact position at a given instant. Positional data are then integrated into an orbit determination model to track the satellite's trajectory continuously. Jason-2 is a French-U.S. satellite launched in 2008 designed to measure rising sea levels and track the effects of climate change. Jason-2 data are being archived by the NODC as part of the Comprehensive Large Array-data Stewardship System (CLASS). humidity sensor humidity sensor HUMIDITY SENSORS are devices that receive a signal or stimulus (as heat or pressure or light or motion etc.) and responds to it, in this case humidity or some measure of the water vapor content of air. oxygen sensor oxygen sensor Any instrument that measures oxygen content in a compound. pyranometer pyranometer Instrument that measure solar radiation. pyrgeometer pyrgeometer A pyrgeometer is a device that measures near-surface infra-red radiation spectrum in the wavelength spectrum approximately from 4.5 µm to 100 µm. This instrument has different sensitivity to short and long-wave radiations and can measure both terrestrial and atmospheric radiation. radiometer radiometer radiometer temperature sensor temperature sensor A sensor used to measure temperature. thermometer thermometer generic thermometer or reversing thermometer use thermometer when temperature is a data type, but the exact instrument used to measure temperature is unknown
