TL;DR: The LALINET (Latin American Lidar Network) as mentioned in this paper is the first fully operative lidar network for aerosol research in South America, probing the atmosphere on regular basis since September 2013.
Journal ArticleDOI
Optical and geometrical properties of cirrus clouds in Amazonia derived from 1 year of ground-based lidar measurements
D. A. Gouveia,Boris Barja,Henrique M. J. Barbosa,Patric Seifert,Holger Baars,Theotonio Pauliquevis,Paulo Artaxo +6 more
TL;DR: In this article, the authors derived the first comprehensive statistics of optical and geometrical properties of upper-tropospheric cirrus clouds in Amazonia using 1 year (July 2011 to June 2012) of ground-based lidar atmospheric observations.
Journal ArticleDOI
Tropospheric and stratospheric wildfire smoke profiling with lidar: mass, surface area, CCN, and INP retrieval
Albert Ansmann,Kevin Ohneiser,Rodanthi-Elisavet Mamouri,Daniel A. Knopf,Igor Veselovskii,Holger Baars,Ronny Engelmann,Andreas Foth,Cristofer Jimenez,Patric Seifert,Boris Barja +10 more
TL;DR: In this article, the authors present retrievals of tropospheric and stratospheric height profiles of particle mass, volume, surface area, and number concentrations in the case of wildfire smoke layers as well as estimates of smoke-related cloud condensation nuclei (CCN) and ice-nucleating particle (INP) concentrations from backscatter lidar measurements on the ground and in space.
Journal ArticleDOI
