Characterization of Asian dust and Siberian smoke with multiwavelength Raman lidar over Tokyo, Japan in spring 2003
(2004-12-02)
[ 1] In the spring of 2003, we observed lofted Asian dust and Siberian forest-fire smoke plumes in the free troposphere over Tokyo, Japan with a dual-wavelength Raman lidar. These data show clear signatures of the optical ...
Multiyear aerosol observations with dual-wavelength Raman lidar in the framework of EARLINET
(2004-07-10)
For the first time, a Raman lidar operating simultaneously in the ultraviolet (UV) and in the visible wavelength range was employed to measure vertical profiles of volume extinction coefficients of particles at 355 and 532 ...
Closure study on optical and microphysical properties of a mixed urban and Arctic haze air mass observed with Raman lidar and Sun photometer
(2004-07)
[1] We present a comprehensive optical and microphysical characterization of an intense haze event observed over Leipzig ( 51.3 degreesN, 12.4 degreesE), Germany, in April 2002. This event was characterized by unusually ...
Siberian forest-fire smoke observed over central Europe in spring/summer 2003 in the framework of earlinet
(ESA PUBLICATIONS DIVISION C/O ESTEC, 2004)
We observed unexpectedly high particle backscattering and extinction in the free troposphere over Leipzig, Germany, in spring/summer 2003. Optical depth was about four times higher than in the respective months of 2000-2002. ...
Optic-fiber scramblers and a fourier transform lens as a means to tackle the problem on the overlap factor of lidar
(ESA PUBLICATIONS DIVISION C/O ESTEC, 2004)
We present an instrumental approach to formation of the light beam in the image space of lidar optical receiver, behind its field stop, aimed at removing some adverse range dependent effects of the lidar overlap factor on ...
Gravity-wave-induced cloud formation in desert dust : Observation with temperature/humidity/aerosol Raman lidar in the framework of earlinet
(ESA PUBLICATIONS DIVISION C/O ESTEC, 2004)
The evolution of three cloud layers that formed during the passage of a gravity wave in a desert dust layer was monitored with an advanced Raman lidar. Dust is characterized in terms of particle optical properties. The ...
Information content of multiwavelength lidar data on the base of Eigenvalues analysis
(ESA PUBLICATIONS DIVISION C/O ESTEC, 2004)
Multiwavelength Raman lidar technique in combination with sophisticated inversion algorithms has been recognized as a new tool to derive information about microphysical properties of atmospheric aerosols. The optical input ...
