Siberian Smoke 2020

Most of Alaska is now covered by smoke from the Siberian Fires as it wraps around a low-pressure system.

A Dust Plume to Remember

While dust routinely blows across the Atlantic Ocean, scientists rarely see plumes as large and dense with particles as the one that darkened Caribbean skies in June 2020.

NASA-NOAA’s Suomi NPP Satellite Analyzes Saharan Dust Aerosol Blanket

Dust storms from Africa’s Saharan Desert traveling across the Atlantic Ocean are nothing new, but the current dust storm has been quite expansive and NASA satellites have provided a look at the massive June plume.

NASA Observes Large Saharan Dust Plume Over Atlantic Ocean

NASA-NOAA’s Suomi NPP satellite observed a huge Saharan dust plume streaming over the North Atlantic Ocean, beginning on June 13. Satellite data showed the dust had spread over 2,000 miles.

NASA’s SAGE III Instrument Observes Aerosol Spike from Australian Fires

The devastating southeastern Australian bushfires that started last September spewed smoke and aerosols higher into the atmosphere than some Earth-observing instruments have ever measured.

Nitrogen Dioxide Levels Rebound in China

With most lockdowns ending and economic activity resuming, levels of the air pollutant have returned to near normal for this time of year.

NASA Satellite Data Show Air Pollution Decreases over Southwest U.S. Cities

On March 19, California was one of the first states to set mandatory stay-at-home restrictions in an attempt to slow the spread of COVID-19. Arizona and Nevada followed suit around April 1.

NASA Funds Four Research Projects on COVID-19 Impacts

Through its Rapid Response and Novel Research in Earth Science (RRNES) initiative, NASA is providing funding for selected, rapid-turnaround projects that make innovative use of satellite data and other NASA resources to address the different environmental, economic and societal impacts of the pandemic.

NASA Monitors Environmental Signals From Global Response to COVID-19

For the past several weeks, much of the world has experienced a new normal: one with fewer cars on the road and more time spent at home.

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 a various impacts of the COVID-19 pandemic.

On Earth Day 50, NASA Researchers Look To the Future

In the 50 years since the first Earth Day, the view from space has revolutionized our understanding of Earth. Looking ahead at the next 50 years, we've asked researchers across the agency about the big questions in their fields and the role they see NASA playing to meet environmental challenges.

Airborne Particle Levels Plummet in Northern India

Satellite data show that aerosol levels have dropped significantly since the COVID-19 lockdown began.

Unusual Weather Leads to Ozone Low Over the Arctic

While such low concentrations of ozone are unusual, they are not unprecedented.

#EarthDayAtHome with NASA

Fifty years ago, on April 22, 1970, people around the world marked the first Earth Day. Thousands gathered to raise awareness about the importance of protecting our beautiful planet for future generations.

NASA Reports Arctic Stratospheric Ozone Depletion Hit Record Low in March

Ozone levels above the Arctic reached a record low for March, NASA researchers report. An analysis of satellite observations show that ozone levels reached their lowest point on March 12 at 205 Dobson units.

NASA Data Aids Ozone Hole’s Journey to Recovery

On September 16, 1987, policymakers and scientists from around the world gathered at the International Civil Aviation Organization’s headquarters in Montreal, preparing to take action on the day’s most urgent topic: Depletion of the Earth’s protective ozone layer.

How NASA is Helping the World Breathe More Easily

Look around. Can you see the air? No? Luckily, many of NASA's Earth-observing satellites can see what the human eye can't -- including potentially harmful pollutants lingering in the air we breathe.

NASA Marks Earth Day’s 50th Anniversary with #EarthDayAtHome

As the world observes the 50th anniversary of Earth Day on Wednesday, April 22, NASA is highlighting the agency’s many contributions to sustaining and improving our home planet’s environment...

NASA Satellite Data Show 30 Percent Drop In Air Pollution Over Northeast U.S.

While less air pollution may seem like a great thing, the recent improvements in air quality around the world, such as over China and Europe, are resulting from efforts (e.g., lockdowns and stay-at-home orders) by cities and countries to reduce the spread of COVID-19.

New NASA Podcast Helps Listeners Explore Our ‘Curious Universe’

NASA’s newest podcast is taking listeners on an adventure to explore the wonders of Earth and help unravel the mysteries of the universe.

NASA Science Keeps the Lights On

Across NASA’s many missions, thousands of scientists, engineers, and other experts and professionals all over the country are doing what they do best, but now from home offices and via video conferencing. With most personnel supporting missions remotely to keep onsite staff at a minimal level in response to COVID-19, the Agency is moving ahead strongly with everything from space exploration to using our technology and innovation to help inform policy makers.

Statement on NASA Goddard’s Coronavirus Prep Actions

Goddard has canceled all non-mission-essential visits to its facilities. Goddard also is closing its Visitor Centers at Greenbelt and at Wallops Flight Facility, Virginia.

Airborne Nitrogen Dioxide Plummets Over China

NASA and European Space Agency (ESA) pollution monitoring satellites have detected significant decreases in nitrogen dioxide (NO2) over China. There is evidence that the change is at least partly related to the economic slowdown following the outbreak of coronavirus.

Explosive Fire Activity in Australia

Fires are burning so fiercely that they are lofting smoke to unusual heights.

NASA Animates World Path of Smoke and Aerosols from Australian Fires

A fleet of NASA satellites working together has been analyzing the aerosols and smoke from the massive fires burning in Australia.
