Rayleigh lidar
WebJan 23, 2015 · Temperature soundings at 30 to 90 km altitude range are conducted by means of a Rayleigh lidar operating at Haute-Provence observatory, hereafter OHP (43.9°N, 5.7°E) since 1978. Rayleigh backscattering of a laser beam in the absence of aerosols is used to measure atmospheric density and temperature [ Hauchecorne and Chanin , 1980 ] … WebJul 22, 2024 · Calibration of an atmospheric lidar is often required due to variations in the electro-optical system. Rayleigh fitting commonly performed may fail under various conditions. Temporal and spatial variations both affect lidar signals. We hence opt for spatiotemporal analysis. We present a novel deep-learning (DL) lidar calibration model …
