- Abstract:
- It is proposed to demonstrate the in situ detection of IO and NO at atmospheric concentrations using a modified OH instrument based on laser-induced fluorescence for which IO and NO detection limits at the sub-ppt level have been calculated with a short time response. Field measurements of IO by long-path absorption have demonstrated the importance of iodine chemistry for the budget of ozone in coastal regions, but an in situ technique for IO deployed on the ground, on ships or on aircraft would enable the global importance of iodine to be established. The absence of direct measurements has left the role of iodine an open question in the upper troposphere and lower stratosphere. Atmospheric measurements of NOx are dominated by chemiluminescent analysers, but there is a need for a direct spectroscopic alternative, particularly at very low concentrations.
