Inversion with regularization for the retrieval of tropospheric aerosol parameters from multiwavelength lidar sounding
(2002-06-20)
We present an inversion algorithm for the retrieval of particle size distribution parameters, i.e., mean (effective) radius, number, surface area, and volume concentration, and complex refractive index from multiwavelength ...
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 2. Case studies
(2001-11-27)
We present the seasonal cycle of optical and physical particle properties over the Indian Ocean based on case studies of six-wavelength aerosol lidar observations performed in the framework of the Indian Ocean Experiment. ...
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 ...
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 ...
Optical and physical characterization of European and Indo-Asian pollution plumes with six-wavelength aerosol lidar
(IEEE COMPUTER SOC, 2001)
Optical and physical particle properties of two typical pollution plumes emitted from the European continent during the Aerosol Characterization Experiment ACE 2, and from the Indo-Asian continent during INDOEX are ...
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 ...
