Round-the-clock temperature profiling in the troposphere with Raman lidar
(INST TROPICAL MEDICINE ROTTERDAM - LEIDEN, 2003)
We discuss the Raman-lidar technology of acquiring temperature profiles of the atmosphere that we have recently developed to facilitate the day-time temperature measurements with lidar. Information on the temperature profile ...
Vertical profiles of atmospheric particle parameters measured with a scanning 6-wavelength 11-channel aerosol lidar
(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. ...
Optical and microphysical characterization of biomass-burning and industrial-pollution aerosols from multiwavelength lidar and aircraft measurements
(2002-11-16)
[1] During the Lindenberg Aerosol Characterization Experiment (LACE 98) simultaneous measurements with ground-based and airborne lidars and with two aircraft equipped with aerosol in situ instrumentation were performed. ...
Relative-humidity profiling in the troposphere with a Raman lidar
(2002-10-20)
We describe a Raman-lidar-based approach to acquiring profiles of the relative humidity of air. For this purpose we combined in one instrument the Raman-lidar techniques that are used for the profiling of water vapor and ...
European pollution outbreaks during ACE 2 : Optical particle properties inferred from multiwavelength lidar and star-Sun photometry
(2002-08)
[1] On the basis of multiwavelength backscatter and 532-nm extinction profiling with lidar at Sagres (37degreesN, 9degreesW), southern Portugal, and optical depth observations with a star photometer at the lidar site and ...
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 ...
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 ...
