Abstract

The invention relates to a double-view-field multi-wavelength Raman laser radar beam splitting system suitable for different cloud base heights. The system comprises a double-view-field device, a large-view-field light path system and a small-view-field light path system. The double-view-field device comprises at least two double-view-field light splitting devices with different sizes so as to adapt to atmosphere detection of different cloud base heights; the double-view-field light splitting device is used for enabling one part of echo signals reflected by the atmosphere to enter the large-view-field light path system and the other part of the echo signals to enter the small-view-field light path system; the large-view-field optical path system and the small-view-field optical path system are both used for screening out optical signals with different wavelengths in corresponding view fields. The splitting system not only can adapt to atmosphere detection of different cloud base heights, but also is simple in structure and convenient to operate, is applied to the laser radar, and can effectively and reliably detect atmosphere parameters of water cloud and aerosol based on double view fields.

Description

technical field [0001] The invention relates to the technical field of atmospheric detection, in particular to a dual-field-of-view multi-wavelength Raman lidar spectroscopic system adaptable to different cloud base heights. Background technique [0002] Aerosol-cloud interaction (Aerosol-Cloud Interaction, ACI) is one of the most uncertain radiative forcing factors in the earth system, and it is also the two major factors that aerosols affect the radiation budget balance of the earth-atmosphere system. One of the main ways. In the aerosol-cloud interaction, aerosols affect the cloud's optical characteristics, cloud amount, water content, and lifetime, and then produce the first type of indirect effect (Twomey effect) and the second type of indirect effect (Albercht effect) on the climate. effects or cloud life cycle effects); meanwhile, the impact of aerosols on clouds also includes semi-direct effects. Therefore, the interaction between aerosols and clouds has an extreme...
