Infrared Working Group

The Infrared Working Group (IRWG) represents a network of infrared Fourier-transform spectrometers that is part of the Network for the Detection of Atmospheric Composition Change (NDACC). It is a multi-national collection of over twenty high resolution spectrometers that regularly record the atmospheric absorption spectrum from sites distributed from pole to pole. The absorption spectra are used to retrieve concentrations of a number of the gaseous atmospheric components, including: O3, HNO3, HCl, HF, CO, N2O, CH4, HCN, C2H6 and ClONO2.
