Observation of Sea Fog Incursion with a Diode-Pumped YAG Portable Lidar
A portable lidar system has been strongly desired for the measurement of local area air pollution, boundary layer meteorology, plume dispersion and cloud physics. However, so far a compact and convenient lidar system has not been well developed. One of the authors constructed a pseudorandom code lidar (RM-CW lidar) system using a diode laser as a light source[1]. It has a limited performance due to the limited power. We proposed and presented a new system[2-3] based on a high repetitive operation, where we adopted a whole solid system using of a Q-switched diode-pumped YAG laser and an avalanche photodiode(APD). Here we report its application to a sea fog observation.
