TOTCAP
Tropospheric Ozone and Tracers from Commercial Aircraft Platforms

The Tropospheric Ozone and Tracers from Commercial Aircraft Platforms (TOTCAP) is an in-situ airborne analyzer that measures tropospheric ozone, carbon dioxide, and water vapor. Ozone is measured using a dual-beam ultraviolet (254 nm) absorption analyzer. Water vapor is detected through second harmonic generation with a tunable diode laser spectrometer that uses a near-infrared (1.37 microns) laser. Carbon dioxide is measured by detecting its absorption in the infrared spectrum at 4.25 microns.
