Product Overview:

The temperature and humidity Raman lidar is based on the Raman-Mie scattering detection principle. The laser emitted by the lidar interacts with atmospheric molecules and aerosol particles along its transmission path. Molecules such as nitrogen and water vapor in the atmosphere produce vibrational-rotational Raman scattering. The Raman scattering signals from nitrogen and water vapor molecules are used to retrieve the atmospheric water vapor mixing ratio profile, while the rotational Raman scattering signals of high and low quantum numbers are used to retrieve the atmospheric temperature profile.

Product Features:

Based on a molecular Raman retrieval algorithm (no need to assume lidar ratio), offering higher retrieval accuracy;

Can be used for calibration and alignment of regional Mie scattering lidars;

Utilizes a high-power laser and large-aperture telescope to address the issues of weak Raman signals and limited detection range.
