Notes from the Field: ATom 2016: World Survey of the Atmosphere

Notes from the Field: ATom 2016: World Survey of the Atmosphere

The Atmospheric Tomography (ATom) mission seeks to understand how short-lived greenhouse gases like ozone and methane contribute to climate change. NASA's DC-8 flying laboratory will fly from Alaska to the tip of South America, then north to Greenland to measure more than 200 gases and particles in the air and their interactions. Read more

Notes from the Field: The Ablation Zone: Where Ice Goes to Die

Notes from the Field: The Ablation Zone: Where Ice Goes to Die

In summer 2016, researchers landed on the Greenland Ice Sheet to study the efficiency of its drainage system. Intensive mapping, monitoring, and measuring of the ice sheet's rivers will help scientists improve estimates of ice loss via surface melt and its effect on global sea level rise. Read more

World of Change: Ice Loss in Glacier National Park

World of Change: Ice Loss in Glacier National Park

Shrinking since at least the early 1900s, the ice cover in Glacier National Park is expected to keep declining until only insignificant lumps remain. These images show changes to the park's ice and surrounding landscape since 1984. Read more

The Carbon Cycle

Carbon flows between the atmosphere, land, and ocean in a cycle that encompasses nearly all life and sets the thermostat for Earth's climate. By burning fossil fuels, people are changing the carbon cycle with far-reaching consequences. Read more

 National Parks from Space

National Parks from Space

The U.S. National Park Service celebrates its centennial in 2016, commemorating 100 years of stewardship of America’s natural and historic treasures. Many of those monuments, scenic rivers, parks, and historic sites are visible from space—where the views are just as compelling. Read more

Notes from the Field: A Satellite Scientist Visits the Ice, Alaska 2016

Notes from the Field: A Satellite Scientist Visits the Ice, Alaska 2016

NASA's Walt Meir uses satellites to study sea ice. But like many modelers and remote sensing researchers, he had never stepped foot on this remote polar icescape. In spring 2016, Meir joined other satellite remote sensing scientists, sea ice modelers, and field researchers in Barrow, Alaska. Read more

Natural Beauty at Risk: Preparing for Climate Change in National Parks

Natural Beauty at Risk: Preparing for Climate Change in National Parks

Many National Parks were created to protect forests and ecosystems from development and fragmentation. But changes in temperature, rainfall, and atmospheric concentrations of carbon dioxide could eventually do as much to remake forests as humans did with saws and fires and bulldozers. Read more

Celebrating a Decade of CloudSat and Calipso

Celebrating a Decade of CloudSat and Calipso

For a decade, the CloudSat and CALIPSO satellites have used radar and lidar to “slice” through clouds and plumes of atmospheric particles to gain a better understanding of the vertical structures of the ephemeral features. Read more

Methane Matters

Methane Matters

The concentration of methane in the atmosphere has been fluctuating, mostly rising. The question is why. Scientists wonder if they have the right monitoring systems in place to answer that question adequately. Read more

Notes from the Field: Arctic-Boreal Vulnerability Experiment (ABoVE)

Notes from the Field: Arctic-Boreal Vulnerability Experiment (ABoVE)

The Arctic Boreal Vulnerability Experiment (ABoVE) is a multi-year field campaign in Alaska and western Canada, involving dozens of research teams. ABoVE researchers are investigating the vulnerability and resilience of ecosystems (such as permafrost, forests, and coastlines) and society to this changing environment. Read more
