ATom

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.

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.

ATom Instrument Calibration and Performance Data

Calibration and in-flight performance data for Ultra-High Sensitivity Aerosol Spectrometers used during ATom deployments is now available.

Two New Datasets from ATom

Flight tracks of the NASA DC-8 during the ATom-1 deployment. The scale to the right represents black carbon mass-mixing ratio in units of ng rBC/kg of air.

New data collected during ATom flights provide measurements of aerosols and black carbon concentrations in the atmosphere.
