This Saildrone was deployed among two others (SD1020, SD1022) from southern New Zealand in austral fall 2019. These data include atmospheric measurements of barometric pressure, air temperature, PAR, wind speed and gust at height of 3.6m and 3.8m, respectively. These data include hydrographic measurements of sea surface temperature, relative humidity, sea water salinity, oxygen concentration in sea water and Chlorophyll concentration at depth of 0.5m. This dataset is available to the public for a wide variety of uses including scientific research and analysis. completed 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 asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0259495 Preview graphic PNG 0259495 NCEI ACCESSION NUMBER 2022-08-17 publication AIR TEMPERATURE BAROMETRIC PRESSURE CHLOROPHYLL CONDUCTIVITY DISSOLVED OXYGEN PHOTOSYNTHETIC ACTIVE RADIATION (PAR) RELATIVE HUMIDITY SALINITY SEA SURFACE TEMPERATURE WIND GUST Wind speed - east-west component (U) Wind speed - north-south component (V) theme NODC DATA TYPES THESAURUS anemometer barometer PAR Sensor instrument NODC INSTRUMENT TYPES THESAURUS in situ theme NODC OBSERVATION TYPES THESAURUS University of Gothenburg dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS University of Gothenburg dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS South Atlantic Ocean South Pacific Ocean Southern Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication GU > University of Gothenburg, Sweden dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 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 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. PAR Sensor PAR Sensor 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)
