A new airborne instrumental payload has been designed for an ultralight aircraft to determine the vertical profile of aerosol optical properties. It is based on Lidar A�rosols UltraViolet A�roport� (LAUVA), a compact backscattering lidar system emitting at the wavelength of 355 nm. We operated this airborne configuration in the Sahel from the city of Niamey (Niger) ...

The Commissariat � l'Energie Atomique (CEA) and the Centre National de la Recherche Scientifique (CNRS) have developed the Lidar A�rosols UltraViolet A�roport� (LAUVA). The new version of this prototype is now commercialized with success under license by the LEOSPHERE Company with the name EZ LIDAR�. This eye-safe lidar is based on a Nd:YAG laser giving pulses of 16 ...

Dissolved silica (DSi) is an important nutrient in freshwater and coastal ecosystems. The availability of DSi is governed by DSi mobilization from the terrestrial system into the limnic system and fluvial transport of DSi to the coasts, respectively. Part of the DSi is retained in the limnic system due to biotic uptake and sedimentation. Anthropogenic influences including eutrophication and ...

Biomass in forest cover is an essential actor in climate regulation. It is one of the principal sinks of atmospheric CO2 and a major water cycle regulator. In the coming years, climate change may generate an increase in the frequency of fires in the ecosystems, which ...
