ATom Airborne Meteorological Measurements for Atmospheric Dynamics

Meteorological Measurement System data captures high-resolution in situ airborne state parameters from NASA's four ATom campaigns. The dataset includes pressure, temperature, turbulence index, and 3D wind vectors to investigate mesoscale and microscale atmospheric phenomena. It was produced by NASA and covers campaigns conducted between 2016 and 2018.

Use Cases

• Analyzing turbulence index and 3D wind vectors to study microscale atmospheric dynamics and diffusion processes.
• Using pressure and temperature data to evaluate chemical reaction rates and calculate accurate mixing ratios for atmospheric chemistry models.
• Investigating mesoscale phenomena like gravity and mountain lee waves by correlating wind field data with other atmospheric constituents.
• Verifying numerical weather and air mass origin models with accurate, high-resolution in situ wind measurements.

Strengths

• Data originates from a state-of-the-art instrument designed for accurate, high-resolution in situ measurements.
• Covers four distinct ATom campaigns, providing repeated global-scale atmospheric sampling.

Limitations

• Specific row counts, file sizes, and detailed column names are not provided across any platform.
• Conflicting last update dates exist between sources: Data.gov lists 2026-03-13, while NASA Earthdata lists 2018-05 21.
