Arctic research expedition likely faces extreme conditions in fast-changing Arctic
Scientists at the National Center for Atmospheric Research (NCAR) have used an ensemble of multiple climate model runs to simulate conditions along potential routes for the MOSAiC polar expedition, using today’s conditions in the “new Arctic.” The results suggest that thinner sea ice may carry the ship farther than would be expected compared to historical conditions and the sea ice around the ship may melt earlier than the 12-month goal. Of the 30 model runs analyzed in the new study, five (17%) showed melt-out in less than a year.

Field campaign flies through icy weather
Scientists are collecting in-flight data in some of the most risky weather for the aviation industry, including freezing rain, freezing drizzle, and sleet. The program is led by the Federal Aviation Administration in partnership with the National Center for Atmospheric Research and other organizations.

Wintertime Arctic Sea ice's long-term rate of decline slows
New research by NASA and NCAR has found that increases in the rate at which Arctic sea ice grows in the winter may have partially slowed down the decline of the Arctic sea ice cover.

Measuring snowfall in Antarctica
Scientists set out to understand how much snow is feeding the Antarctic ice sheets and whether it is enough to offset the ice lost to the ocean.
