★ [AAS22-06] Lidar development for hyper-dense remote observation of urban atmosphere
Keywords:hyper-dense observation, lidar, atmospheric temperature, water vapor density, remote sensing
For water vapor concentration distribution measurement, we propose a differential absorption lidar (DIAL) using diode laser based transmitters. For temperature measurements in daytime, we propose a high-spectral-resolution lidar (HSRL) using a potassium Faraday filter. The Faraday filter acts as a blocking filter for suppression of narrow Mie scattering, and a very narrow filter for getting temperature information from Doppler-broadened Rayleigh spectrum.
