On its second worldwide tour, the Atmospheric Tomography (ATom) team starts by surveying the north’s polar regions during winter, which is marked by a build-up of pollution from the United States, Canada, northern China, and Russia. In the spring, sunlight spurs chemical reactions that remove those pollutants and greenhouse gases from the atmosphere.

ATom Postcard - Azore Islands to Kangerlussuaq
May 18, 2017, 7 a.m.
Read moreAtmospheric scientists Bernadett Weinzierl of the University of Vienna, Paul Newman of Goddard Space Flight Center, and Róisín Commane of Harvard University sent back a video postcard from the last three legs of the Atmospheric Tomography, or ATom mission. Departing Ascension Island in the tropics, the science team traveled up the Atlantic to Terceira Island in the Azores off the coast of Portugal, and then back to the Arctic by way of Kangerlussuaq, Greenland. Finally the team crossed North America to return home to Palmdale, California. || The ATom mission aboard NASA’s DC-8 aircraft and 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.

ATom Postcard - Kona, Hawaii
Feb. 17, 2017, 6 a.m.
Read moreAtmospheric scientist Jack Dibb of the University of New Hampshire sent a video postcard from the Hawaii leg of the Atmospheric Tomography or ATom mission. On its second worldwide tour, the ATom team flew into Kona, Hawaii, to study small particles like sulfate and nitrate in the atmosphere. Volcanoes like Kilauea, in Hawaii, constantly release sulfate particles, which can oxidize to make sulfuric acid, a component of acid rain.
