Tracking high-latitude climate change requires an understanding of the fluxes between the atmosphere, ocean, and ice. However, efforts to determine surface fluxes at high latitudes face formidable challenges. Observations are sparse and difficult to obtain. In high latitudes, cold temperatures, high winds, and sea spray and riming (which can cover instruments with ice) combine to make conditions hostile for in situ observations. The unique conditions in high-latitude regions mean that lessons learned in equatorial and subtropical regions do not necessarily translate into improvements in high-latitude fluxes.
