The ATom aircraft prepares to depart from Punta Arenas in southern Chile on October 14, 2017. During ATom-3, the science team flew over Antarctica and below the ozone hole before continuing on their journey north over the Atlantic Ocean to Greenland and returning to California.
Data collected by the Aerosol Microphysical Properties (AMP) instrument during the Atmospheric Tomography (ATom) Mission is now available.
Generalized overview of ATom flights. During each of the four campaigns, ATom flights originated from California, flew south over the Pacific Ocean, then north to the western Arctic, southwest to New Zealand, east to Chile and the Atlantic Ocean, north to Greenland, and returned to California across North America. During flights, the aircraft continuously profiled the atmosphere from 0.2 to 12 km altitude.
The Atmospheric Tomography Mission (ATom) has released multi-instrument merged data from all four flight campaigns spanning from 2016 - 2018.
Circles mark the locations of the 139 selected profiles sampling the remote troposphere. Circle color indicates HCHO column densities integrated over each ATom profile. Data are overlain on global gridded OMI HCHO column densities averaged over the mission. From Wolfe et al. (2019) (see dataset references).
New data from NASA's Atmospheric Tomography Mission (ATom) provide hydroxyl and formaldehyde column density in the remote troposphere.
