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%.

NCCS and Partners Highlight Recent Scientific Advancements at Virtual SC20 Conference

The NASA Center for Climate Simulation (NCCS) and NASA Goddard Space Flight Center partners will highlight their recent advances during SC20, the International Conference for High Performance Computing, Networking, Storage, and Analysis being held virtually November 9–19, 2020.

NASA Research Exhibit to Highlight Science and Engineering Advances at the Virtual SC20 Supercomputing Conference

From assessing COVID-19’s global impacts to helping NASA return humans to the Moon to searching the cosmos for new exoplanets, researchers from across NASA, with university and industry partners, will highlight their latest advances, enabled by the agency’s supercomputers, at SC20—the International Conference for High Performance Computing.

NASA and NOAA Scientists Develop Method to Create Continuous Ozone Climate Data Record

To help scientists monitor Earth's stratospheric ozone for years to come, NASA Goddard Space Flight Center and NOAA Earth System Research Laboratories researchers used the NASA Center for Climate Simulation (NCCS) Discover supercomputer to create consistency between two satellite ozone datasets.

NASA Hydrological Forecast System Supports Food and Water Security in Africa and Middle East

The new NASA Hydrological Forecast and Analysis System (NHyFAS) joins the U.S. Agency for International Development's Famine Early Warning System Network to help Africa and the Middle East better prepare for droughts and related disasters. NHyFAS runs monthly at the NASA Center for Climate Simulation (NCCS).

California Heatwave Fits a Trend

A new study shows heatwaves in Southern California have increased in frequency, duration, and intensity over recent decades.

NASA's Aqua Satellite Captures Devastating Wildfires in Oregon

Huge numbers of wildfires have broken out in Oregon. Some began in August, but the majority started after a huge unprecedented windstorm that occurred on Sep. 7, 2020.

A Dangerous Storm Nears the Gulf Coast

Hurricane Laura is poised to cause an unusually large and damaging storm surge.

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).
