This is the first in-situ validation of the reanalysis atmospheric flux and observations. Given the importance of the region in the context of global sea-level rise and recent advancements of numerical models at ice-ocean-atmosphere interface, the problems identified and the new parameterization in this paper make a difference.
Short summary
Few observations exist in the Amundsen Sea. Consequently, studies rely on reanalysis (e.g., ERA5) to investigate how the atmosphere affects ocean variability (e.g., sea-ice formation and melt). We use data collected along ice shelves to show that cold, dry air blowing from Antarctica triggers large ocean heat loss, which is underestimated by ERA5. We then use an ocean model to show that this bias has an important impact on the ocean, with implications for sea-ice forecasts.
