This summer, with sea ice across the Arctic Ocean shrinking to below-average levels, a NASA airborne survey of polar ice just completed its first flights. Its target: aquamarine pools of melt water on the ice surface that may be accelerating the overall sea ice retreat

The Atmospheric Tomography, or ATom, mission is the first to survey the atmosphere over the oceans. Scientists aboard NASA's DC-8 flying laboratory will journey from the North Pole south over the Pacific Ocean to New Zealand and then across to the tip of South America and north up the Atlantic Ocean to Greenland. ATom will discover how much pollution survives to the most remote corners of the earth and assess how the environment has changed as a result.

Atmospheric Carbon and Transport–America, or ACT-America, is a multi-year airborne campaign that will measure concentrations of carbon dioxide and methane in relation to weather systems. The study will gather real-time measurements from research aircraft and ground stations to improve the ability to detect and quantify the surface sources and sinks of the gases.

A new map created with measurements from an airborne instrument developed by NASA’s Jet Propulsion Laboratory, Pasadena, California, reveals the devastating effect of California’s ongoing drought on Sierra Nevada conifer forests.

Starting this week, 32 undergraduate students begin an eight-week NASA airborne science field experience designed to immerse them in the agency's Earth science research.

On Friday June 3, 2016, the Oceans Melting Greenland mission had its first successful test of the system for dropping ocean probes from the Gulfstream-III aircraft into the ocean. The team dropped a single probe into the Gulf of Mexico about 100 miles offshore of Houston as a T-38 chase aircraft monitored.

Operation IceBridge, NASA’s airborne survey of polar ice, ended its eighth spring Arctic campaign on May 21. During their five weeks of operations, mission scientists carried out six research flights over sea ice and ten over land ice.

NASA's upcoming Coral Reef Airborne Laboratory (CORAL) field experiment will observe entire reef ecosystems in more of the world's reef area – hundreds of times more -- than has ever been observed before.

New Orleans and surrounding areas continue to sink at highly variable rates due to a combination of natural geologic and human-induced processes, finds a new NASA/university study using NASA airborne radar.

NAAMES, or the North Atlantic Aerosols and Marine Ecosystems Study, is a five-year NASA-funded study that aims to better define the relationship between the ocean and the atmosphere. NAAMES is the first NASA Earth Venture-Suborbital mission focused on studying the coupled ocean ecosystem and atmosphere using ships and aircraft simultaneously.

Next week NASA and the Republic of Korea’s National Institute of Environmental Research (NIER) embark on the collaborative Korea United States Air Quality study (KORUS-AQ). The KORUS-AQ field campaign will combine observations from aircraft, satellites, ships and ground stations with air quality models to assess and monitor air quality across urban, rural and coastal areas.

Operation IceBridge, NASA’s airborne survey of polar ice, completed its first Greenland research flight of 2016 on April 19, kicking off its eighth spring Arctic campaign. This year’s science flights over Arctic sea and land ice will continue until May 21.

A new NASA airborne field experiment planned for this summer will make key airborne measurements of clouds and smoke particles over the southeastern Atlantic Ocean to help scientists understand a major challenge to our understanding of climate science.

NASA is sending scientists around the world in 2016 – from the edge of the Greenland ice sheet to the coral reefs of the South Pacific – to delve into challenging questions about how our planet is changing and what impacts humans are having on it.

The first deployment of one of NASA's most ambitious research studies of Earth's atmosphere will take place this July and August. The Atmospheric Tomography mission will take off aboard the agency's DC-8 flying laboratory on a 26-day journey from the North Pole down the Pacific Ocean to New Zealand and then across to the tip of South America and back north up the Atlantic Ocean to the Arctic.

The new NASA airborne mission Oceans Melting Greenland (OMG) will pave the way for improved estimates of sea level rise by addressing the question: To what extent is the ocean melting Greenland’s ice from below? The mission will observe changing water temperatures and glaciers that reach the ocean around Greenland from 2015 to 2020. The OMG data set will complement earlier and ongoing observations of Greenland's melting ice sheet by satellite sensors such as the Gravity Recovery and Climate Experiment (GRACE), which gives a precise measurement of the loss of mass from Greenland, and other airborne programs including NASA's Operation IceBridge, which measures bedrock topography and the depth of the overlying snow and ice.

A contingent of NASA airborne instruments and scientists on the ground has joined colleagues from space agencies in Gabon and Europe this month to study the dense African tropical forests in Gabon.

NASA and the Republic of Korea are developing plans for a cooperative field study of air quality in May and June to advance the ability to monitor air pollution accurately from space.  The Korea U.S.-Air Quality study (KORUS-AQ) will assess air quality across urban, rural and coastal areas of South Korea using the combined observations of aircraft, ground sites, ships and satellites. Findings will play a critical role in the development of observing systems of ground and space-based sensors and computer models to provide improved air quality assessments for decision makers.

NASA and NOAA are teaming up again to send NASA’s remotely piloted Global Hawk out over the Pacific to take a closer look at storms brewed by this year’s strong El Niño. The observation flights are part of an ongoing NOAA mission, called Sensing Hazards with Operational Unmanned Technology (SHOUT).

In just two 10-minute overflights, an airborne NASA synthetic aperture radar proved it could pinpoint areas of disturbance in Peru's Nasca lines World Heritage Site. The data collected on the two flights will help Peruvian authorities fully catalog the thousand-year-old designs drawn on the ground in and around the site for the first time, as well as giving them a new tool for protecting the fragile constructions from both careless humans and natural disturbances such as floods.

The amount of methane gas escaping from the ground during the long cold period in the Arctic each year and entering Earth’s atmosphere is likely much higher than estimated by current carbon cycle models, concludes a major new study led by San Diego State University and including scientists from NASA’s Jet Propulsion Laboratory, Pasadena, California.

The North Atlantic Aerosols and Marine Ecosystems Study (NAAMES) is an interdisciplinary investigation resolving key processes controlling marine ecosystems and aerosols that are essential to our understanding of Earth system function and future change.
