LIDAR FOR OZONE SENSING IN THE UPPER TROPOSPHERE - BOTTOM STRATOSPHERE

摘要

The field of application of the utility model is intended for remote determination of the vertical distribution of ozone (BPO) based on atmospheric control methods. The objective of the technical solution is to obtain lidar signals with the aid of a lidar operating at 299/341 nm in the altitude range of 5-20 km with a high spatial resolution of 10 m. The problem is solved as follows, in the proposed utility model, a differential absorption lidar is used, which consists of one Nd: YAG laser and one SRS cell with hydrogen, which makes it possible to convert laser radiation from a single source of study at a wavelength of 266 nm into radiation with a pair of wavelengths of 299/341 nm and a telescope Increasing the spatial resolution of lidar signals is achieved by installing a new photon counter (PHCOUNT 6/2), which accumulates them for 2048 time intervals. 2 yl.
