Could COVID-19 Have Seasons?

Scientists are probing environmental data from reanalysis models in the hopes of finding answers.

NASA's Aqua Satellite Uses Infrared to Highlight Apple Fire's Burn Scar

The latest on the Apple fire in San Bernardino, Calif.

Assimilating Satellite Data Yields a First Look at COVID-19’s Impact on Carbon Dioxide

Combining NASA satellite data with a computer model yields a first look at changes in global carbon dioxide concentrations after Coronavirus Disease 2019 (COVID-19) restrictions began during early 2020. The study ran on a custom configuration of the NASA Center for Climate Simulation (NCCS) Discover supercomputer.

Methane Emissions Continue to Rise

Rapid growth from 2008–2017 built upon the rise in the atmospheric concentration of the gas that has been happening for more than a century.

Could COVID-19 Have Seasons? Searching for Signals in Earth Data

A race is on to figure out whether COVID-19 will wax and wane with the seasons. Atmospheric and hydrologic models produced by NASA and other institutions may be key to that research.

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.

Dust Traverses the Atlantic Ocean

A tremendous plume of dust from North Africa drifts toward the Caribbean and contiguous United States.

NCCS Upgrade Markedly Improves Skill of NASA Seasonal Prediction System

NASA’s upgraded seasonal prediction system shows substantial improvement in performance, infrastructure, and forecast skill over its predecessor, per a broad set of experiments carried out at the NASA Center for Climate Simulation (NCCS).

NASA Earth Data Powers Energy-Saving Decisions

NASA's long-term, global view of Earth from space includes data on sunlight, wind, temperature and precipitation, all key elements in understanding how our planet works.

#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 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 Study Adds a Pinch of Salt to El Niño Models

When modeling the El Niño-Southern Oscillation (ENSO) ocean-climate cycle, adding satellite sea surface salinity — or saltiness — data significantly improves model accuracy, according to a new NASA study.

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.

Greenland, Antarctica Melting Six Times Faster Than in the 1990s

An international scientific team has shown that Greenland and Antarctica are losing ice six times faster than they were in the 1990s.

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.

New 3D View of Methane Tracks Sources and Movement around the Globe

NASA’s new 3-dimensional portrait of methane concentrations shows the world’s second largest contributor to greenhouse warming, the diversity of sources on the ground, and the behavior of the gas as it moves through the atmosphere

NCCS-Hosted Models Probe Fires on Two Continents

As fires wreaked havoc in the western U.S.and Australia, NASA Center for Climate Simulation-supported computer models combined with observations were probing the dynamics and effect of these fires.

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.

NASA Satellite Offers Urban Carbon Dioxide Insights

Using data from NASA's Orbiting Carbon Observatory-2, researchers found links between the population density of cities and how much carbon dioxide they produce per person.

Antarctica Melts Under Its Hottest Days on Record

Ice caps and glaciers felt the heat as temperatures reached 18.3°C (64.9°F).

Moisture Pummels the Pacific Northwest

Following an exceptionally wet January, an atmospheric river carried even more moisture into the region in February.
