Atmospheric Profiles of Hydroxyl and Formaldehyde

Full flight tracks for ATom missions 1

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.

Column-average CO2 Concentrations from ACT-America

ACT-America column-average carbon dioxide concentrations

Column-average CO2 measured during the first 20 minutes of flight off the coast of New Jersey on July 11, 2016, for the ACT-America mission.

A new dataset provides remotely-sensed column-average carbon dioxide concentrations measured over the Eastern US.
