Martian Gravity Wave Observations from THEMIS, Mars Years 26-33

Data from the Thermal Emission Imaging System (THEMIS) instrument on Mars, used to study atmospheric gravity waves during the northern summer. The dataset includes processed spectral arrays for eight Mars years (26 to 33), separated into daytime and nighttime observations. It was created by J. Michael Battalio and colleagues in November 2022.

Use Cases

• Analyzing gravity wave spectral properties based on baseline orientation and length bins.
• Comparing atmospheric wave activity between Martian daytime and nighttime conditions.
• Studying interannual variability of gravity waves across eight Mars years.
• Mapping the spatial distribution of wave activity based on swath centroid longitude and latitude.

Strengths

• Covers eight Mars years (26 to 33) of observations, providing multi-year temporal coverage.
• Includes separate, processed data arrays for both daytime and nighttime conditions.
• Provides spectral data for top-10 gravity wave peaks per swath, as mentioned in the description.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
