Tracking CO2 emission reductions from space: A case study at Europe's largest fossil fuel power plant
A new study by Nassar and co-authors uses OCO-2 and OCO-3 observations to demonstrate spaceborne capability for tracking power plant emissions in close to real time. >

National CO2 Budgets informed by atmospheric CO2 measurements
What are the emissions and removals of CO2 (carbon dioxide) for countries around the world? And how much do fossil fuel emissions, trade, and changing land carbon stocks contribute to these net fluxes? >

Cozette Parker's unique path to an engineering job at JPL
I had been watching people at JPL doing what I felt was interesting work. It seemed hard, but I thought, “I’m not a stupid girl; I can go to college and learn how to do this stuff,” so that’s what I did. >

NASA satellite captures rising carbon dioxide after major forest fires
Tom Pongetti once saw a tree explode. It was September 2020. The COVID-19 pandemic shuttered most on-site operations at NASA’s Jet Propulsion Laboratory (JPL). At the same time, one of the most devastating fires ever to accost Los Angeles was wreaking havoc on the mountain slopes above JPL. >

How it started, how it's going: As a NASA satellite is built, a science community is built, too
It was a warm April day in 2003 when 22 scientists, squinting in the sun, lined up neatly on a pathway at Caltech. Vines draped over arches in the background. Everyone flashed a smile as the camera clicked. >

Career profile: Annmarie Eldering on leadership at JPL
Annmarie Eldering first came to NASA’s Jet Propulsion Laboratory (JPL) in 1999 for a summer fellowship, and stayed for over 20 years. Recently retired, she experienced the excitement, surprises, and stresses that come with leading the development of new satellites. >

How is climate change impacting shellfish in the ocean?
A NASA satellite managed at the Jet Propulsion Laboratory is measuring the amount of carbon dioxide in the atmosphere. But things get tricky when that CO2 finds a place to hide. >

Career profile: David Crisp and international work at NASA-JPL
Julia Marshall met David Crisp during an earthquake. Both had been separately invited to a 2011 meeting in Japan by the Japan Aerospace Exploration Agency (JAXA), an hour's train ride away from Tokyo. Julia had bought her first business suit for the occasion, and was standing at the podium, dressed to impress. But as she began her talk, the building started shaking. >

Did the pandemic slow down climate change?
The global pandemic has been a difficult time, but you may have wondered: Have we at least put the brakes on climate change by staying home and not driving so much? Unfortunately, not. >

Cooperation, not Competition: The Making of a Space Sensor
When some people go hiking, it’s so they can escape to the “pleasure in the pathless woods” (as Lord Byron put it). But for a carbon cycle scientist, walking through a forest means they haven’t quite left their work behind. >

A Climate Conundrum: Why Didn’t Atmospheric CO2 Fall During the Pandemic?
During the COVID-19 pandemic, carbon dioxide increased at the same rate in the atmosphere despite lower emissions, say researchers from campus and JPL; plus, what is good for ozone reduction is bad for methane removal. >

NASA Science Enables First-of-its-Kind Detection of Reduced Human CO2 Emissions
For the first time, researchers have spotted short-term, regional fluctuations in atmospheric carbon dioxide (CO2) across the globe due to emissions from human activities. >

JPL Scientist Speaks with White House Committee
Schoolchildren and office-workers alike have gotten used to showing off their bedrooms and living rooms during virtual meetings and class lessons. But imagine showing off your home office to the White House. >

A Wall of Green, a Breath of Fresh Air
Green spaces can create urban oases, and a NASA mission has the data to show they also help pull carbon dioxide out of the air in cities. >

Spotlight on Lan Dang: Mentoring the next generation
Lan Dang works on the Orbiting Carbon Observatory-2 and Orbiting Carbon Observatory-3 satellites as the Science Data System Lead. When she’s not busy handling the data the satellite sends back, she’s pursuing her other passion: mentoring new hires and local schoolkids. >

Satellites Could Help Track if Nations Keep Their Carbon Pledges
Scientists used satellite measurements of carbon dioxide to detect small atmospheric reductions over areas under coronavirus lockdowns. The approach could help track emissions more quickly in the future >

Oct. 28, 2021
On eve of climate summit, researchers sharpen emissions tracking
Remote sensing tools could reveal whether nations are adhering to their climate pledges >

How Scientists Are Using the International Space Station to Study Earth’s Climate
On Earth, we often look toward the sky longing to know what resides in the rest of the universe. Meanwhile, 250 miles above our planet, the International Space Station is looking back. >
