A NASA airborne study has returned to the field for a second year of science flights to advance the accuracy of short- and long-term climate models.

The Aerosol Cloud meTeorology Interactions oVer the western ATlantic Experiment (ACTIVATE) began the third of six planned flight campaigns — two campaigns each year beginning in 2020 and ending in 2022 — in late January at NASA's Langley Research Center in Hampton, Virginia.

This figure depicts nearly eight years of science flights across the globe by the NASA Airborne Science Program (ASP) aircraft serving the needs of the Earth Science community. Flight tracking is achieved using the Mission Tools Suite (MTS). 

Despite racing against impending harsh weather conditions, a red and white World War II aircraft flew slowly and steadily over the icy waters surrounding Greenland in August and September. Three weeks delayed by pandemic restrictions, scientists from NASA’s Jet Propulsion Laboratory inside this retrofitted DC-3 plane started dropping hundreds of probes as part of an annual expedition known as the Oceans Melting Greenland(OMG) Project.

While the agency's satellites image the wildfires from space, scientists are flying over burn areas, using smoke-penetrating technology to better understand the damage.

With the help of NASA’s Ames Research Center in California’s Silicon Valley, Swift Engineering of San Clemente, California, completed a two-hour flight test of their Swift High-Altitude Long-Endurance (HALE) UAS. The applications of the technology – for science, agriculture, and disaster response – could have a real impact on our everyday lives.

Delta-X, a new NASA airborne investigation, is preparing to embark on its first field campaign in the Mississippi River Delta in coastal Louisiana. Beginning in April, the Delta-X science team, led by Principal Investigator Marc Simard of NASA's Jet Propulsion Laboratory in Pasadena, California, will be collecting data by air and by boat to better understand why some parts of the delta are disappearing due to sea-level rise while other parts are not.

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.

NASA is inviting members of the media to a behind-the-scenes tour and briefing on five new research campaigns that will take to the field in 2020 to explore questions critical to understanding our home planet. The event is scheduled for Tuesday, Jan. 7, from 7 a.m. to 12:30 p.m. PST at NASA’s Armstrong Flight Research Center, Building 703, in Palmdale, California.

NASA has announced it will use Wallops Island Flight Facility, just south of Chincoteague Island, as a jumping-off point to study Atlantic snowstorms starting in January.

It’s the first major field campaign to study East Coast snowstorms in 30 years.

The Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) study will send a high-altitude aircraft (flying from Savannah, Georgia) and a cloud-sampling aircraft (flying from Wallops Island) to look closer at how snow is distributed in the clouds.

NASA explains that the “cloud processes” responsible for snowstorms are difficult to measure, and forecast models can’t reproduce them very well. That makes for poor snowfall predictions.

“People see pictures of these big swaths of clouds and think they’re snowing everywhere, but they’re not,” said IMPACTS principal investigator Lynn McMurdie at the University of Washington in Seattle. “Inside the clouds are these long narrow regions of more intense snow bands. We’re trying to understand why they form and how they evolve with the developing storm.”

Since the last time East Coast snowstorms were studied from the air, instruments have become much more advanced. NASA says now is “an ideal time to conduct a well-equipped study to identify key processes and improve remote sensing and forecasting of snowfall.”

NASA’s ER-2 and P-3 aircraft will fly for three six-week deployments.

A new instrument with its eye on the Moon is taking off aboard a high-altitude NASA plane to measure the Moon’s brightness and eventually help Earth observing sensors make more accurate measurements.

IceBridge has been gathering data on Arctic and Antarctic ice sheets, glaciers and sea ice for 10 years. It was designed to ‘bridge the gap’ in between the Ice, Cloud and land Elevation Satellite (ICESat), which stopped collecting data in 2009, and ICESat-2, which launched in September 2018. Over the past decade, IceBridge has been based out of airports in Alaska, Greenland, Chile, Argentina and Antarctica – but for this final polar campaign, it has a new base at Hobart in Tasmania, Australia.

Wildfires in the Arctic often burn far away from populated areas, but their impacts are felt around the globe. From field and laboratory work to airborne campaigns and satellites, NASA is studying why boreal forests and tundra fires have become more frequent and powerful and what that means for climate forecasting, ecosystems and human health.

This summer, NASA is embarking on several field campaigns across the world to investigate longstanding questions surrounding fire and smoke. Aircraft will fly through smoke and clouds to improve air quality, weather and climate forecasting, and investigate fire-burned forests to capture ecosystem changes that have global impact.

Snowflakes that cover mountains or linger under tree canopies are a vital freshwater resource for over a billion people around the world. To help determine how much freshwater is stored in snow, a team of NASA-funded researchers is creating a computer-based tool that simulates the best way to detect snow and measure its water content from space.
