Potential of lidar backscatter data to estimate solar aerosol radiative forcing
(2006-02-01)
The potential to estimate solar aerosol radiative forcing (SARF) in cloudless conditions from backscatter data measured by widespread standard lidar has been investigated. For this purpose 132 days of sophisticated ...
Raman lidar observations of aged Siberian and Canadian forest fire smoke in the free troposphere over Germany in 2003 : Microphysical particle characterization
(2005-09-02)
Dual-wavelength Raman lidar observations were regularly carried out at Leipzig (51.3 degrees N, 12.4 degrees E) from May to August 2003. The measurements showed that particle backscatter and extinction coefficients in the ...
Information content of multiwavelength lidar data with respect to microphysical particle properties derived from eigenvalue analysis
(2005-09-01)
The multiwavelength Raman lidar technique in combination with sophisticated inversion algorithms has been recognized as a new tool for deriving information about the microphysical properties of atmospheric aerosols. The ...
Daytime operation of a pure rotational Raman lidar by use of a Fabry-Perot interferometer
(2005-06-10)
We propose to use a Fabry-Perot interferometer (FPI) in a pure rotational Raman lidar to isolate return signals that are due to pure rotational Raman scattering from atmospheric nitrogen against the sky background. The ...
Ice formation in Saharan dust over central Europe observed with temperature/humidity//aerosol Raman lidar
(2005-04-26)
[1] Three gravity-wave-induced clouds and a glaciating altocumulus layer were continuously monitored with lidar at Leipzig, Germany, on 21 November 2003. The midtropospheric clouds formed in Saharan dust at heights from ...
Particle extinction measured at ambient conditions with differential optical absorption spectroscopy. 1 : System setup and characterization
(2005-03-20)
We describe an instrument for measuring the particle extinction coefficient at ambient conditions in the spectral range from 270 to 1000 nm. It is based on a differential optical absorption spectroscopy (DOAS) system, which ...
Microphysical aerosol parameters from multiwavelength lidar
(2005-03)
The hybrid regularization technique developed at the Institute of Mathematics of Potsdam University (IMP) is used to derive microphysical properties such as effective radius, surface-area concentration, and volume ...
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 ...
