PO.DAAC is pleased to announce the dataset release of the Saildrone 2021 Arctic field campaign for the Multi-Sensor Improved SST (MISST) project, which provides surface and oceanographic measurements from two Saildrone unmanned surface vehicles (USV) during the period 6 July 2021 to 20 October 2021. Power issues caused the actual sampling period to end on 20 September 2021. MISST is funded by NASA through the National Ocean Partnership Program (NOPP). The overall mission objective was to measure atmospheric and oceanographic conditions in Alaskan arctic waters in support of improving satellite-derived sea surface temperature measurements. A special emphasis during the 2021 campaign was to better understand the spatial/temporal scales of air-sea covariance in the Chukchi Sea. Each Saildrone was equipped to measure air temperature and relative humidity, barometric pressure, surface skin temperature, wind speed and direction, wave height and period, seawater temperature and salinity, chlorophyll fluorescence, and dissolved oxygen. Both vehicles measured near surface currents with 300 kHz acoustic Doppler current profilers (ADCP). NetCDF data files contain 1-minute averaged, georeferenced trajectory data for the USV, and 5-minute averaged ADCP data. More information on the project can be found at the Saildrone mission page.
