The ATom mission aboard NASA's DC-8 flying laboratory is sampling world-wide in one of the most extensive surveys of the atmosphere to date, measuring over 200 gases as well as airborne particles. The science team is particularly interested in methane, tropospheric ozone and black carbon particles, which have strong effects on climate and which all have both human and natural origins.
Below are interviews with four scientists participating in the research flights: * Donald Blake, UC Irvine * Róisín Commane, Harvard University * Tom Ryerson, NOAA * Jack Dibbs, University of New Hampshire
Snakes on a NASA plane! No, not that kind of snake. Donald Blake from the University of California Irvine with the #EarthExpedition ATom mission explains why "snakes" are part of the Whole Air Sampler from behind the scenes on the DC-8 aircraft.
To measure the background atmosphere you need a sensitive instrument. Róisín Commane of Harvard University with the #EarthExpedition ATom mission explains how her instrument uses lasers to detect greenhouse gases.
Flying into "clean" air during #EarthExpedition ATom mission, Jack Dibbs of the University of New Hampshire explains what he expects to find on his aerosol filters as they travel to the remotest parts of the atmosphere.
