Aerosol data collected during Atmospheric Tomography Mission (ATom) will inform on new particle formation occurrence in the tropics.
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.
The NOAA Single Particle Soot Photometer (SP2) is a laser-induced incandescence instrument primarily used for measuring the black carbon mass content of individual particles.
Black carbon concentrations were measured over remote regions of the Earth during NASA's Atmospheric Tomography (ATom) Mission.
