Short summary
Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) measurements have been analysed to measure the vertical distribution of phosgene (COCl2) in the UTLS using new spectroscopic data. To highlight its seasonal and latitudinal variability, MIPAS measurements of 2 days/month during 2008 have been analysed. The results show a strong latitudinal variability of COCl2 with the largest VMR values observed in the tropical regions. The seasonality is fairly low, apart from the polar regions.
