TOTE-VOTE Ground Site Lidar Data: Stratospheric Ozone Profiles

NASA's Tropical Ozone Transport Experiment – Vortex Ozone Transport Experiment (TOTE-VOTE) campaign collected ground site data from December 1995 to February 1996. The dataset includes lidar measurements from the NASA GSFC STROZ-LITE and JPL Table Mountain Facility instruments at Mauna Loa, focusing on stratospheric ozone profiles, aerosol properties, and atmospheric transport processes. Nineteen flights using a DC-8 aircraft and balloon sondes complemented the ground-based measurements.

Use Cases

• Analyzing stratospheric ozone profile variability based on DIAL O3 lidar measurements.
• Studying aerosol backscattering, depolarization, and extinction in the Pacific region from lidar data.
• Modeling atmospheric transport filaments from the arctic polar vortex using combined aircraft and ground data.
• Quantifying reactive nitrogen species (NOx, NOy) and ozone concentrations from chemiluminescence instrument data.
• Investigating particle size distributions in the stratosphere from optical particle counter (FSSP) measurements.

Strengths

• Data collection is complete, providing a finalized record of the campaign.
• Campaign employed multiple high-precision instruments, including a 4-channel chemiluminescence instrument and a four-laser DIAL system.
• Combines data from 19 aircraft flights with ground-based lidar measurements for a multi-platform perspective.

Limitations

• Column names and dataset size (rows, file size) are unspecified across all sources.
• Last updated date conflicts between sources (1996-02-19 and 2026-04-09), suggesting metadata inconsistency.
• Limited temporal coverage (three months) and geographic focus (Pacific region, Mauna Loa).
