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.

Body

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).

Body

New data from NASA's Atmospheric Tomography Mission (ATom) provide hydroxyl and formaldehyde column density in the remote troposphere.

The Atmospheric Tomography (ATom) Mission is an Earth Venture Suborbital-2 mission to measure greenhouse gases and human-produced air pollution in remote areas.

Body

Merged data from ATom's first two flight campaigns (August 2016 and February 2017) were updated with revised data along with edits to the author list and user guide.
