NASA's Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument aboard the Terra satellite imaged some of the burned area on June 29, 2020.
Rapid Mapping Technology to Help Caribbean Through Looming Hurricane Season
Powerful satellite technology can help Caribbean countries better manage natural disasters and boost climate resilience, as the region braces for a busy hurricane season in 2020.
Volcanic Emissions Can Change Clouds
For two weeks in mid-May, NASA satellites observed volcano tracks nearly every day.
Ice Melt Linked to Accelerated Regional Freshwater Depletion
Seven of the regions that dominate global ice-mass losses are melting at an accelerated rate, a new study shows, and the quickened melt rate is depleting freshwater resources that millions of people depend on.
Snow Mass Estimates Now More Reliable
Warming surface temperatures are known to have driven substantial reductions in the extent and duration of northern hemisphere snow cover.
NASA Probes Environment, COVID-19 Impacts, Possible Links
Scientists are using information from NASA's Earth-observing satellites, on-the-ground sensors and computer-based datasets to study the environmental, economic and societal impacts of the COVID-19 pandemic.
Study Suggests Rainfall Triggered 2018 KÄ«lauea Eruption
Volcanoes erupt when molten rock called magma rises to the surface, and many factors, from the shape of the volcano to the composition of the magma, factor into the timing of eruptions. In the case of KÄ«lauea, a new, NASA-funded study published April 22, 2020, in the journal Nature points to another eruption factor: prolonged, sometimes heavy rainfall in the months leading up to the event.
NASA Satellite Data Show 30 Percent Drop In Air Pollution Over Northeast U.S.
Over the last several weeks, NASA satellite measurements have revealed significant reductions in air pollution over the major metropolitan areas of the Northeast United States.
NASA, University of Nebraska Release New Global Groundwater Maps and U.S. Drought Forecasts
NASA researchers developed new satellite-based, weekly global maps of soil moisture and groundwater wetness conditions and one- to three-month U.S. forecasts of each product.
Air Quality Satellite Constellation Begins Taking Shape
On Feb. 18, 2020, a new era began in an international effort to improve air-quality science and forecasting around the world to help reduce the impact of air pollution on human health and the environment.
