Wind waves in the North Atlantic and Arctic from ship navigational radar (SeaVision system) and wave buoy Spotter during three research cruises in 2020 and 2021

The purpose of this dataset is to provide in situ wind waves observations in the open ocean. The dataset consists of significant wave heights, wave periods, wave directions, wave energy frequency spectra, meteorological data and other related parameters. Parameters of the wind waves measured with Spotter wave buoy and SeaVision system on the basis of navigational ship X-band radar. The dataset was collected in almost 50 locations during three research cruises on the research vessels Akademik Sergey Vavilov and Akademik Ioffe in the North Atlantic (August 2020 and June 2021) and Arctic (August 2021). The dataset is the supplement to the manuscript "Wind waves in the North Atlantic from ship navigational radar: SeaVision development and its validation with Spotter wave buoy and WaveWatch III" (Tilinina et al., 2022). Technical details, maps with expedition tracks and detailed methodology of the wind wave parameters calculations from both SeaVision and Spotter raw data are described in the manuscript.
