New NASA research shows that by releasing heat and moisture through a large hole in sea ice known as a polynya, the exposed ocean fuels the formation of more clouds that trap heat in the atmosphere and hinder the refreezing of new sea ice.

Smoke from several large wildfires burning in Northern California can be seen traveling miles into the atmosphere.

Ship Tracks off the Kamchatka Peninsula

PacificOcean_amo_2015208 A scientist, Yi-Chun (Jean) Chen, at NASA’s Jet Propulsion Laboratory, and his colleagues were able to show how open-cell versus closed cell clouds affect the brightness, or albedo, of ship tracks.

Using data from MODIS on-board both Aqua and Terra and from the Multi-angle Imaging SpectroRadiometer (MISR) on Terra, the team studied the relationship between ship-emitted aerosols and cloud properties. The results suggested that aerosol plumes increased the amount of clouds and albedo in open-cell formation areas; where as, areas with closed-cells were less susceptible to aerosol plumes.
