NASA Field Campaigns Resume with GMAO and NCCS Support

After delays due to COVID-19, NASA and partner organizations enthusiastically mounted several field campaigns in spring-summer 2021. Key to campaign success are 12-kilometer-resolution atmospheric forecasts provided by NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office (GMAO) and NASA Center for Climate Simulation (NCCS).

Unusual Snowfall in Greenland

The remnants of Hurricane Larry dropped abundant snowfall on Greenland just as the summer melt season was coming to an end.

Flash Floods from Ida Swamp the Northeast

Many of the worst-hit areas in Delaware, Pennsylvania, New Jersey, and New York saw 6 to 10 inches of rain fall in just a few hours.

Hurricane Ida Batters Louisiana

Preliminary reports suggest it is the fifth-strongest storm ever to make landfall in the continental U.S.

Rain and Warmth Trigger More Melting in Greenland

The island’s vast ice sheet underwent multiple bouts of widespread melting this summer, exacerbated in August 2021 by rain.

NCCS User Spotlight: Dr. David New

To better understand how early-career scientists are using NASA Center for Climate Simulation (NCCS) resources, we interviewed NASA post-doc David New, who fine-tunes weather prediction models at NASA Goddard’s Global Modeling and Assimilation Office.

Study Projects a Surge in Coastal Flooding, Starting in 2030s

In the mid-2030s, every U.S. coast will experience rapidly increasing high-tide floods, when a lunar cycle will amplify rising sea levels caused by climate change.

Exceptional Heat Hits Pacific Northwest

In June 2021, all-time temperature records fell in multiple cities in the U.S. and Canada during a “historic and dangerous” heatwave.

NASA Helps Map Impact of COVID-19 Lockdowns on Harmful Air Pollution

For tiny airborne-particle pollution, known as PM 2.5, researchers using NASA data found that variability from meteorology obscured the lockdown signals when observed from space.

Records Fall in Early Summer Heatwave

Extreme heat has descended on the southwestern United States, with several states enduring temperatures near and above record highs for June.

Heatwave Scorches the Middle East

A phenomenon known as a “heat dome” set the stage for remarkably high temperatures as meteorological summer got under way.

NCCS User Spotlight: Robin Kovach

To celebrate World Ocean Day, the NASA Center for Climate Simulation (NCCS) spoke with one of NASA Goddard Space Flight Center’s ocean scientists, Robin Kovach.

NCCS-Enabled Satellite Data Assimilation Reveals Vegetation Changes from Massive Australian Bushfires

To better understand how Australia’s unprecedented 2019–2020 fire season affected vegetation, NASA Goddard Space Flight Center scientists and international collaborators mounted an experiment at the NASA Center for Climate Simulation (NCCS), assimilating NASA satellite data into a computer model and analyzing the output.

NCCS User Spotlight: Lesley Ott

As part of NASA’s Earth Day celebration, this spotlight shines on Lesley Ott — from her growing up in the Washington, DC suburbs with a mother who taught math and science to her challenging work today as a research meteorologist in NASA Goddard’s Global Modeling and Assimilation Office.

NASA’s 2021 Virtual Earth Day Event – Online, April 21–24

NASA’s 2021 Virtual Earth Day Event – Online, April 21–24 You’re invited to NASA’s 2021 Virtual Earth Day Event, held April 21-24. Registration is FREE and open to the public!

Potent Atmospheric Rivers Douse the Pacific Northwest

In mid-January 2021, the Pacific Northwest of North America was soaked by several episodes of heavy rainfall, leading to widespread flooding and landslides.

The Climate Events of 2020 Show How Excess Heat is Expressed on Earth

By most accounts, 2020 has been a rough year for the planet. It was the warmest year on record, just barely exceeding the record set in 2016 by less than a tenth of a degree according to NASA's analysis.

NCCS-Enabled Science Advances Being Presented at Online AMS Annual Meeting

From more accurate hydrology forecasts to improved understanding of cyclone dynamics, science advances enabled by NASA Center for Climate Simulation (NCCS) resources are the subject of posters and virtual presentations at the 101st Annual Meeting of the American Meteorological Society (AMS 101), being held online January 10–15, 2021.

NASA Discoveries, R&D, Moon to Mars Exploration Plans Persevere in 2020

"NASA has impressed the nation with our resilience and persistence during the pandemic," said NASA Administrator Jim Bridenstine.

Water Limitations in the Tropics Offset Carbon Uptake from Arctic Greening

New research shows that as Earth's climate is changing, increased carbon absorption by plants in the Arctic is being offset by a corresponding decline in the tropics.

NCCS Supports Monitoring the Global Decline of Air Pollution During the COVID-19 Pandemic

NASA Goddard Space Flight Center and university scientists researched the decline and subsequent recovery of nitrogen dioxide related to COVID-19 stay-at-home orders around the globe by combining a near-real-time computer simulation with surface observations using substantial NASA Center for Climate Simulation (NCCS) resources.

NCCS, CISTO, and Partners Present Advances at Virtual AGU Fall Meeting

Researchers from the NASA Center for Climate Simulation (NCCS), its parent Computational Information & Sciences and Technology Office (CISTO), NASA Goddard Space Flight Center, and university partner organizations are participating in the Scientific Program at the 2020 American Geophysical Union (AGU) Fall Meeting, being held online 1–17 Dec 2020.

Monitoring the Global Decline of Air Pollution During the COVID-19 Pandemic

Nitrogen dioxide (NO2) is an important air pollutant formed during the combustion of fossil fuels. The reduced human activities in the wake of the COVID-19 pandemic led to sharp reductions in surface NO2 around the globe.

Monitoring COVID-19-Related Changes in Carbon Dioxide from Space

As the COVID-19 pandemic altered human activity across the planet in 2020, NASA satellites provided unique global views that allowed scientists to track changes in air pollution, energy usage, and greenhouse gas emissions as they happened.

NASA Model Reveals How Much COVID-related Pollution Levels Deviated from the Norm

Using computer models to generate a COVID-free 2020 for comparison, NASA researchers found that since February, pandemic restrictions have reduced global nitrogen dioxide concentrations by nearly 20%.
