TOTE-VOTE: Radiosonde Data from 1995-1996 Atmospheric Transport Campaign

NASA's TOTE-VOTE_Sondes_Data contains radiosonde measurements from the Tropical Ozone Transport Experiment – Vortex Ozone Transport Experiment campaign conducted from December 1995 to February 1996. Nineteen flights using a NASA DC-8 aircraft and balloon sondes aimed to measure the transport of air filaments between the Arctic polar vortex and the tropical stratospheric reservoir. The dataset likely contains atmospheric profiles of temperature, winds, and water vapor indicators.

Use Cases

• Analyzing vertical profiles of atmospheric temperature and winds based on radiosonde measurements.
• Studying the transport of air filaments from the polar vortex to midlatitudes based on the campaign's stated objective.
• Investigating stratospheric ozone and aerosol distributions using data from the complementary aircraft instruments described.
• Modeling background atmospheric transport processes in the Pacific region during winter 1995-1996.

Strengths

• Data originates from a focused NASA campaign with 19 documented flights.
• Campaign utilized multiple, specific instruments (e.g., NCAR NOxyO3, DIAL system, MTP) for complementary measurements.
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata and Data.gov), indicating curation and importance.

Limitations

• Column names and exact data structure are unknown, limiting precise usability assessment.
• Metadata conflicts exist: one source lists a last updated date of 2026-04-09, while another lists 1996-02-19.
• Dataset size (rows, file size) is not provided on any platform.
