Abstract. We present a novel methodology to estimate cloud condensation nuclei (CCN) concentrations from spaceborne CALIPSO (Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observations) lidar measurements. The algorithm utilizes (i) the CALIPSO-derived backscatter extinction coefficient, depolarization ratio, aerosol subtype information; (ii) normalized volume size distributions refracti...

Derived by combining data from the CloudSat radar and the CALIPSO lidar, the so-called radar-lidar geometrical profile product (RL-GeoProf) allows for characterization of the vertical and spatial structure of hydrometeor layers. RL-GeoProf is one of the standard data products of the CloudSat Project. In this paper we describe updates to the RL-GeoProf algorithm. These improvements include a sig...
Satellite observations have shown that the Asian Summer Monsoon strongly influences the upper troposphere and lower stratosphere (UTLS) aerosol morphology through its role in the formation of the Asian Tropopause Aerosol Layer (ATAL). Stratospheric Aerosol and Gas Experiment II solar occultation and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) lidar observations s...
[1] During the dry season, anthropogenic fires in tropical forests and peatlands of equatorial Asia produce regionally expansive smoke clouds that have important effects on atmospheric radiation and air quality. Here we estimated the height of smoke on Borneo and Sumatra and characterized its sensitivity to El Niño and regional drought. We used Multiangle Imaging Spectroradiometer (MISR) satell...
OBJECTIVE To describe part of the results of the CALIPSO study, i.e. to provide seafood consumption data on high seafood consumers in France and its contribution to n-3 long-chain (LC) PUFA intake. DESIGN AND SUBJECTS A total of 1011 individuals aged 18 years and over, who consumed fish and seafood at least twice weekly, were recruited. A consumption survey and a local 'total diet study' were...
An analytical inversion method has been developed to estimate the vertical profile of SO2 emissions from volcanic eruptions. The method uses satellite-observed total SO2 columns and an atmospheric transport model (FLEXPART) to exploit the fact that winds change with altitude – thus, the position and shape of the volcanic plume bear information on its emission altitude. The method finds the vert...
Based on the 8 years' (January/2008-December/2015) cloud phase information 40 from the GCM-Oriented Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Cloud Product (GOCCP), aerosol products from CALIPSO, and meteorological parameters from the ERA-Interim products, the present study investigates the effects of atmospheric dynamics on the supercooled liquid cloud fractio...
