Such a concentration studies in the multi-components gaseous mixture essentially by lidar technique is a complex problem in atmospheric pollution monitoring. There are the fluorescence lidar and differential absorption lidar the most preferable for the detection of iodine molecules at very low concentration levels. Laboratory lidar studies and lidar equation simulation in these lidar variants gave the iodine molecules fluorescence differential cross section and iodine molecules absorption cross section in good agreement with earlier data. The experimental results confirm the possibility of the molecular iodine lidar sensing at low pressure and the measuring results treatment allows to get iodine molecules parameters. 收起
