ATom: In Situ Tropical Aerosol Properties and Box Model Outputs

Get Data

Documentation Revision Date: 2020-12-23

Dataset Version: 1

Summary

This dataset provides particle number concentration and size distributions of dry aerosol particles measured by the Aerosol Microphysical Properties (AMP) instrument package during airborne NASA's Atmospheric Tomography (ATom) mission (Atom 1-4). It also contains two box model outputs and back trajectory data. This dataset was used to understand new particle formation, their link to convection, and particle initial growth in the tropical upper troposphere. This dataset is pending QA and documentation.

QA and documentation for this dataset is in progress.

Figure 1: Ambient pressure as a function of latitude colored by the measured number concentration of particles with Dp from 3 - 60 nm over the Pacific Ocean for a) ATom 1, July-August 2016; b) ATom 2, January-February 2017; c) ATom 3, September-October 2017; and d) ATom 4, April-May 2018). Periods of flight in clouds, over continents and near airports have been removed.
