We had a gently warm morning for takeoff to Hawaii, with sun peaking through the clouds. Getting above the clouds we had spectacular views of snow capped peaks. We made a missed approach at Cold Point, population 109 at the last census. Low clouds prevented us from seeing too much there visually, but through the […]
The title of this post is borrowed from Phillip Pullman’s prequel to his Dark Materials trilogy. I loved these books as a child, and by happy coincidence ended up studying for my masters at the college on which Jordan College in the novels is based. The reference to journeys northward and parallels with searching for […]
I have been looking forward to the second leg of the ATom mission since I first worked up the plan, collaborating with the others on the leadership team and with the flight operations crew from NASA’s Armstrong Flight Center. It would start in the hot, high desert in Palmdale, California, and journey to the high […]
I’m Róisín Commane, a researcher at Harvard University working with Steve Wofsy (ATom PI) and Bruce Daube (chief engineer) to measure CO2, CH4, N2O and CO concentrations during ATom. As the project evolves, I’m hoping to provide some insight into both the science we are doing and what it means to work on an aircraft […]
Last Friday, July 29, was the first real science flight of the mission. Driving down to the base at 4am, Mumford and Sons’ ‘Cave’ blasting through the stereo, I definitely felt excited (and a little sleepy). On-board we powered up the instruments and ran through our pre-flight checklist. We’d made some changes the previous day […]
Hi there! Our team got out of the field a few days ago after a successful field campaign with a lot of great data to analyze! For the coming blog posts, we will be sharing with you the different kind of measurements we made during our stay at the ice camp and but also describe […]
In the last two weeks, we’ve wrapped up the test flights and major preparations for NASA’s ATom mission. ATom is an airborne science experiment aboard the DC-8 flying laboratory that will study the most remote parts of the Earth’s atmosphere. We want to learn how much pollution reaches areas most people would consider untouched by […]
I’m Christina Williamson, a postdoctoral scientist at CIRES CU-Boulder/NOAA-ESRL interested in Atmospheric Aerosols, the small particles in the air that cause haze, and on which clouds are formed. I’m working with a few colleagues from NOAA to take a suite of instruments on NASA’s ATom mission that will measure the number and size of particles […]
Take 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, 0.03 percent carbon dioxide – that’s 99.93 percent of the atmosphere. But the trace gases and airborne particles that make up that last approximately 0.07 percent are what NASA’s Atmospheric Tomography (ATom) mission is interested in. ATom is a chemistry mission to study the movement […]
