Probing the Hazy Mysteries of Marine Clouds

A new NASA airborne science mission will take researchers on coordinated flights above, through and below the clouds over the western North Atlantic Ocean. The Aerosol Cloud Meteorology Interactions Over the Western Atlantic Experiment (ACTIVATE) is scheduled to begin the first of six flight campaigns this week at NASA's Langley Research Center in Hampton, Virginia.

The HU-25 Falcon, pictured here, will fly under and through the clouds, where a suite of instruments will take samples directly from the surrounding air to measure everything from aerosol properties to droplet composition to gas. Instrument probes are visible here protruding from the top of the aircraft. Credits: NASA/David C. Bowman
