Airborne Multi-AXis Differential Optical Absorption Spectroscopy (AMAX-DOAS) Data

Project:

CONTRAST

Summary

This dataset contains Airborne Multi-AXis Differential Optical Absorption Spectroscopy (AMAX-DOAS) data collected on the Gulfstream-V High-performance Instrumented Airborne Platform for Environmental Research (NSF/NCAR GV HIAPER) aircraft during the CONvective TRansport of Active Species in the Tropics (CONTRAST) project. The data consists of two types of files: 1) volume mixing ratio of bromine monoxide in air (combined DOAS fit and vmr retrieval error (30%) expressed as volume mixing ratio of bromine monoxide in air) and 2) volume mixing ratio of iodine monoxide in air (combined DOAS fit and vmr retrieval error (20%) expressed as volume mixing ratio of iodine monoxide in air). Mixing ratios are derived by parameterization method on limb spectra integrated column measurements. BrO slant columns are corrected for stratospheric BrO above 18km using CAMChem.
