Topic: DC-8Written by Joe Atkinson
The study, led by researchers at the Georgia Institute of Technology, found brown carbon particles released into the air from burning trees and other organic matter are much more likely than previously thought to travel to the upper levels of the atmosphere, where they can interfere with rays from the sun – sometimes cooling the air and at other times warming it. ![]() Brown carbon particles produced by wildfires such as the ones that have scorched parts of Georgia and Florida this year are more likely than previously thought to travel to the upper levels of the atmosphere and impact climate.

NASA’s Convective Processes Experiment (CPEX) will try to improve Weather ForecastsWritten by Carol Rasmussen
Called the Convective Processes Experiment (CPEX), the campaign is using NASA’s DC-8 airborne laboratory outfitted with five complementary research instruments designed and developed at NASA. The plane also will carry small sensors called dropsondes that are dropped from the plane and make measurements as they fall. ![]() Convective storm clouds over Fort Lauderdale, Florida, preceding Hurricane Sandy in 2012.

NASA’s DC-8 Airborne Laboratory begins reseach into Nighttime Thunderstorms over the Great PlainsWritten by Alan Buis
The Plains Elevated Convection at Night, or PECAN, project began June 1st and continues through mid-July. Participants from eight research laboratories and 14 universities are collecting storm data to find out how and why storms form. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Antarctic 2011 IceBridge Campaign ConcludesWritten by Alan Brown
The IceBridge flight and science team flew a record 24 science flights during the six-week campaign, recording data from a suite of sophisticated instruments on the thickness and depth of Antarctic ice sheets and glacial movement. The aircraft departed its deployment base at Punta Arenas, Chile, Tuesday morning November 22nd and after a refueling stop in Santiago, Chile, set course for Los Angeles International Airport for customs clearance. The flying lab continued on to the Dryden Aircraft Operations Facility in Palmdale, arriving about 8:30pm that evening after almost 15 hours in the air. ![]() The frozen, inhospitable surface features of Alexander Island in Antarctica were viewed at close range during one of the final low-level flights by NASA's DC-8 flying laboratory during the 2011 Operation IceBridge mission.

Watching the Birth of an IcebergWritten by Patrick Lynch
NASA’s Operation IceEarth Bridge, the largest airborne survey of Earth’s polar ice ever flown, is in the midst of its third field campaign from Punta Arenas, Chile. The six-year mission will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice. ![]() NASA's Operation Ice Bridge discovers an emerging crack that cuts across the ice shelf of Pine Island Glacier.

NASA Continues Critical Survey of Antarctica’s Changing IceSteve Cole – Headquarters, Washington, D.C.
Researchers are flying a suite of scientific instruments on two planes from a base of operations in Punta Arenas, Chile: a DC-8 operated by NASA and a Gulfstream V (G-V) operated by the National Science Foundation and the National Center for Atmospheric Research. The G-V will fly through early November. The DC-8, which completed its first science flight October 12th, will fly through mid-November. ![]() NASA’s Operation IceBridge mission comprises the largest airborne research campaign ever flown over Earth’s polar region. The mission is designed to continue critical ice sheet measurements in a period between active satellite missions and help scientists understand how much the major ice sheets of Greenland and Antarctica could contribute to sea level rise.
