ATom Flight Track Meteorological and Tagged CO Tracer Data

Modeled meteorological conditions and tagged carbon monoxide tracer concentrations are provided along the flight paths of the Atmospheric Tomography Mission. The dataset is derived from NASA's GEOS-5 data assimilation products, interpolated to the horizontal tracks for each of the four ATom deployments. It originates from the Global Modeling and Assimilation Office at NASA Goddard Space Flight Center.

Use Cases

• Analyzing the contribution of specific regional sources to total atmospheric carbon monoxide using tagged tracer concentrations.
• Studying the meteorological context (e.g., winds, temperature, pressure) of airborne atmospheric sampling campaigns.
• Validating and improving global atmospheric chemistry and transport models with flight-track-aligned model output.

Strengths

• Data is derived from a sophisticated NASA model (GEOS-5) that assimilates satellite, ground-based, and airborne observations.
• Covers four distinct ATom deployment campaigns, providing repeated global-scale sampling.
• Model output is physically consistent, adhering to atmospheric laws and original measurement statistics.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date, reporting both 2018-05-21 and 2026-03-13.
