Dual-wavelength Raman lidar observations of the extinction-to-backscatter ratio of Saharan dust
(2002-05-01)
[1] For the first time, height profiles of the extinction-to-backscatter ratio (lidar ratio) of desert dust particles were simultaneously measured at 355 and 532 nm. The observations were performed with an advanced Raman ...
An intercomparison of aerosol light extinction and 180 degrees backscatter as derived using in situ instruments and Raman lidar during the INDOEX field campaign
(2002)
[1] Aircraft in situ and Raman lidar profiles of aerosol light extinction (sigma(ep)) and 180degrees backscattering (beta(p)) are compared for 6 days during the Indian Ocean Experiment (INDOEX). The measurements of sigma(ep) ...
One-year observations of particle lidar ratio over the tropical Indian Ocean with Raman lidar
(2001-12-15)
Observations of the extinction-to-backscatter ratio (lidar ratio) of South and Southeast Asian aerosol particles are presented for the wavelength of 532 nm. Raman lidar measurements were performed in the Maldives (4.1 ...
Vertical profiling of optical and physical particle properties over the tropical Indian Ocean with six-wavelength lidar 1. Seasonal cycle
(2001-11-27)
For the first time the seasonal cycle of optical and physical particle properties over the Indian Ocean was observed with a six-wavelength aerosol lidar. The measurements were performed in the framework of the Indian Ocean ...
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 ...
