European pollution outbreaks during ACE 2 : Microphysical particle properties and single-scattering albedo inferred from multiwavelength lidar observations
Mueller, D.; Ansmann, A.; Wagner, F.; Franke, K.; Althausen, D. (2002-08-06)We present vertically resolved physical particle properties and the single-scattering albedo at 532 nm of pollution plumes advected from the European continent out over the Atlantic Ocean. The parameters follow from the ... -
Indo-Asian pollution during INDOEX : Microphysical particle properties and single-scattering albedo inferred from multiwavelength lidar observations
Mueller, D.; Franke, K.; Ansmann, A.; Althausen, D.; Wagner, F. (2003-10-07)[1] We present for the first time a comprehensive data set of vertically resolved physical particle properties, and the single-scattering albedo at 532 nm, derived from multiwavelength lidar observations of pollution plumes ... -
An intercomparison of aerosol light extinction and 180 degrees backscatter as derived using in situ instruments and Raman lidar during the INDOEX field campaign
Masonis, S.J.; Franke, K.; Ansmann, A.; Mueller, D.; Althausen, D.; Ogren, J.A.; Jefferson, A.; Sheridan, P.J. (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
Franke, K.; Ansmann, A.; Mueller, D.; Althausen, D.; Wagner, F.; Scheele, R. (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 ... -
Optical and physical characterization of European and Indo-Asian pollution plumes with six-wavelength aerosol lidar
Mueller, D.; Ansmann, Albert; Franke, K.; Althausen, D.; Wandinger, U. (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 ... -
Optical properties of the Indo-Asian haze layer over the tropical Indian Ocean
Franke, K.; Ansmann, A.; Mueller, D.; Althausen, D.; Venkataraman, C.; Reddy, M.S.; Wagner, F.; Scheele, R. (2003-01)[1] Multiwavelength backscatter and extinction profiling was performed with a unique aerosol Raman lidar at Hulhule (4degreesN, 73degreesE), Maldives, as part of the Indian Ocean Experiment (INDOEX) between February 1999 ... -
Vertical profiles of atmospheric particle parameters measured with a scanning 6-wavelength 11-channel aerosol lidar
Althausen, D.; Mueller, D.; Ansmann, Albert; Wandinger, U.; Franke, K.; Wagner, F. (SPIE, 2003)The transportable scanning six-wavelength eleven-channel aerosol lidar of the Insitute for Tropospheric Research represents the most powerful tool for a comprehensive characterization of atmospheric particles with lidar. ... -
Vertical profiling of optical and physical particle properties over the tropical Indian Ocean with six-wavelength lidar 1. Seasonal cycle
Mueller, D.; Franke, K.; Wagner, F.; Althausen, D.; Ansmann, A.; Heintzenberg, J. (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 ... -
Vertical profiling of the Indian aerosol plume with six-wavelength lidar during INDOEX : A first case study
Ansmann, A.; Althausen, D.; Wandinger, U.; Franke, K.; Mueller, D.; Wagner, F.; Heintzenberg, J. (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 ...
