Abstract: The Differential Absorption Lidar (DIAL) offers a way to perform ozone measurements in the troposphere with the spatial and temporal resolutions needed for both short and long term studies. Only a few DIAL system have been ...

Abstract: Today several lidar networks around the world provide large datasets that are extremely valuable for aerosol and cloud research. Retrieval of atmospheric constituent properties from lidar profiles requires detailed analysis ...

Abstract: Although the qualitative influence of mountains over the atmosphere has been known for a long time, numerous deficiencies, linked to orography, are still noted, either in forecasts by regional models, or in the long-term ...

Abstract: About six years ago, the planned field experiment Pyrenean Experiment (PYREX) was presented in the Bulletin. After a successful field phase in October and November 1990, and much work to prepare a consistent database, ...

Abstract: This study compares cirrus-cloud properties and, in particular, particle effective radius retrieved by a Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO)-like method with two similar methods using ...

Abstract: he characterization and the precise measurements of atmospheric pollutant?s concentration are essential to improve the understanding and modeling of urban air pollution processes. The QualAir platform at the Université ...

Abstract: ajor disruptions of the aviation system from recent volcanic eruptions have intensified discussions about and increased the international consensus toward improving volcanic ash warnings. Central to making progress is to ...

Abstract: Aerosols and clouds have important effects on Earth's climate through their effects on the radiation budget and the cycling of water between the atmosphere and Earth's surface. Limitations in our understanding of the global ...

Abstract: The Cloudnet project aims to provide a systematic evaluation of clouds in forecast and climate models by comparing the model output with continuous ground-based observations of the vertical profiles of cloud properties. ...
