New Data from the Atmospheric Tomography (ATom) Mission

ATom mission logo

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

Five new datasets from ATom provide measurements of greenhouse gases and human-produced air pollution from 2016 to 2018.

Estimates of the height of the planetary boundary layer (PBL) are available from the Atmospheric Carbon and Transport - America (ACT-America) airborne campaign.

Atmospheric Photolytic Rates from ATom

Atmospheric photolytic rates for ozone and nitrogen dioxide were estimated using nine global chemistry-climate or chemistry-transport models.

Merged Data from the Atmospheric Tomography Mission

ATom flights

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.

Atmospheric gas data from all four seasonal flight campaigns (Summer 2016, Winter 2017, Fall 2017, and Spring 2018) are now available from the ACT-America mission.
