ATom: Observed and GEOS-5 Simulated CO Concentrations with Tagged Tracers for ATom-1

This dataset contains carbon monoxide (CO) observations at 10-second intervals from flights during the ATom-1 campaign in 2016 and simulated CO concentrations from the Goddard Earth Observing System version 5 (GEOS-5) model for the corresponding locations along the ATom flight tracks. The Atmospheric Tomography Mission (ATom) is a NASA Earth Venture Suborbital-2 mission studying the impact of human-produced air pollution on greenhouse gases and on chemically reactive gases in the atmosphere. The airborne observations were collected using the Quantum Cascade Laser System (QCLS) instrument, a high-frequency laser spectroscopy instrument for in situ atmospheric gas sampling. This dataset provides a direct comparison of observational and simulated CO that will be used to inform future atmospheric modeling experiments. The dataset also contains simulated tagged-CO tracer concentrations, which represent the contribution of specific regional sources to the total simulated CO. This dataset contributes to one of the ATom mission objectives to create an observation-based chemical climatology of important atmospheric constituents and their reactivity in the remote troposphere.

graphic-preview-description CO (ppb) from the QCLS observations (left) and GEOS-5 analysis (right) for the ATom-1 circuit including all 11 research flight segments. The GEOS-5 CO is taken from the analysis closest to the mid-point of the flight time and interpolated to the flight track following the longitude, latitude and pressure given in observations. Both model forecast and ATom measurements are averaged into a sample rate of one per 360-second. Data in the troposphere are plotted in a circle; data in the stratosphere are plotted in a diamond (from Strode et al. 2018).
