As the climate warms and Arctic sea ice retreats, more research vessels and commercial ships are sailing into the Arctic Ocean, but the accuracy and sensitivity of regional weather and marine forecasts for these hazardous waters still lag well behind those of their lower-latitude counterparts, with significant differences between regional models. Direct measurements of atmospheric conditions, such as cloud cover and solar radiation can help to evaluate and improve these models.
