PO.DAAC is pleased to announce the dataset release of the Saildrone 2022 Arctic field campaign for the Multi-Sensor Improved SST (MISST) project, which provides surface and oceanographic measurements from two Saildrone uncrewed surface vehicles (USV) during the period of time from 18 June 2022 to 17 August 2022. These two Saildrone deployments for MISST were funded by NASA through the National Ocean Partnership Program (NOPP). The campaign objective was to measure atmospheric and oceanographic conditions in Alaskan arctic waters, specifically in collaboration with the Distributed Biological Observatory (DBO; https://www.pmel.noaa.gov/dbo/; https://dbo.cbl.umces.edu/), and in support of improving satellite-derived sea surface temperature measurements in the Arctic.

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). Additionally, seven temperature data loggers were positioned vertically along the hull to provide further information on thermal variability near the ocean surface. NetCDF data files contain 1-minute averaged, georeferenced trajectory data for the USV, 5-minute averaged ADCP data, and 1-minute averaged temperature logger data.
