The Canadian FTIR Observing Network (CAFTON) is a network of nine Fourier transform infrared (FTIR) spectrometers deployed across Canada. CAFTON coordinates the measurements of these spectrometers and integrates the atmospheric data with two atmospheric models to characterize atmospheric composition, determine transport pathways, and identify pollutant sources across Canada. CAFTON's four permanent sites are the Toronto Atmospheric Observatory (TAO), the Dalhousie Atmospheric Observatory (DAO), the Polar Environment Atmospheric Research Lab (PEARL), and Environment Canada's Centre for Atmospheric Research Experiments (CARE).
