Comparison of the radiative impact of aerosols derived from vertically resolved (lidar) and vertically integrated (Sun photometer) measurements : Example of an Indian aerosol plume
(2001-10-16)
Radiative forcing calculations both at the top of the atmosphere (TOA) and at the surface were done for vertically varying particle properties and their approximation through vertically constant properties. The data sets ...
European pollution outbreaks during ACE 2 : Lofted aerosol plumes observed with Raman lidar at the Portuguese coast
(2001-09-27)
During the Second Aerosol Characterization Experiment (ACE 2) in the summer of 1997, four pollution outbreaks from the European continent were monitored at Sagres (37 degreesN, 9 degreesW), Portugal, by applying the Raman ...
Scanning 6-wavelength 11-channel aerosol lidar
(2000-11)
A transportable multiple-wavelength lidar is presented, which is used for the profiling of optical and physical aerosol properties. Two Nd:YAG and two dye lasers in combination with frequency-doubling crystals emit ...
Physical properties of the Indian aerosol plume derived from six-wavelength lidar observations on 25 March 1999 of the Indian Ocean Experiment
(2000-05-01)
A major pollution outbreak from the Indian subcontinent was observed with a six-wavelength aerosol lidar at Hulule island (4.1 degrees N, 73.3 degrees E) on 25 March 1999 during the Indian Ocean Experiment. From the observed ...
Microphysical particle parameters from extinction and backscatter lidar data by inversion with regularization : experiment
(2000-04-20)
We present effective radius, volume, surface-area, and number concentrations as well as mean complex refractive index of tropospheric particle size distributions based on lidar measurements at six wavelengths. The parameters ...
Vertical profiling of the Indian aerosol plume with six-wavelength lidar during INDOEX : A first case study
(2000-04-01)
During the Intensive Field Phase (IFP) of the Indian Ocean Experiment (INDOEX) lasting from 15 February to 26 March 1999, a large number of pollution outbreaks from India and southeast Asia were observed with a unique ...
