ORCAS Trace Organic Gas Analyzer (TOGA) VOC Data

Summary

This dataset contains trace organic gas analyzer (TOGA) data taken aboard the NCAR G-V during the ORCAS (The O2/N2 Ratio and CO2 Airborne Southern Ocean Study) project. VOCs are important to understand ozone in the atmosphere. VOCs measured include hydrocarbons, oxygenates, halocarbons, nitrogen and sulfur compounds, isoprene, methacrolein, MVK, and acetone.
