Mie LIDAR Observations of Tropospheric Aerosol over Wuhan

Wuhan is a rapidly developing large city in central China. To analyze the aerosol characteristics over Wuhan, the optical properties of the nocturnal aerosol layers in the lower troposphere were observed using a ground-based LIDAR(Light Detection And Ranging) located in the Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing (LIESMARS) from Wuhan University, China (11...

Stratospheric aerosol measurements by dual polarisation lidar

We present measurements of stratospheric aerosol made at Aberystwyth, UK (52.4 N, 4.06 W) during periods of background aerosol conditions. The measurements were made with a lidar system based on a 532 nm laser and two polarisation channels in the receiver. When stratospheric aerosol amounts are very small, as at present, this method is, potentially, free of a number of systematic errors that be...

Lidar measurements of aerosol depolarization ratio

Lidar measurements of the aerosol depolarization ratio provide highly reliable informations to discriminate between spherical and non-spherical particles in the atmosphere and they can help to distinguish between liquid and solid phase aerosols. These measurements can be performed by using a linearly polarized laser source and a hardware configuration of the receiving system including two chann...
