TL;DR: In this article, the authors show that the resulting planetary-scale blocking of solar radiation by the smoke is larger than any previously documented wildfires and of the same order as the radiative forcing produced by moderate volcanic eruptions.

TL;DR: In this article, the authors use space-borne CALIPSO lidar to track the spatiotemporal evolution of the smoke plumes before their detection at OHP and extrapolate the OHP observations to a regional scale.

TL;DR: In this article, the authors explored the possible impact of deep convective overshooting over land by six simultaneous soundings of water vapour, particles and ozone in the lower stratosphere next to Mesoscale Convective Systems (MCSs) during the monsoon season over West Africa in Niamey, Niger in 2006.

TL;DR: The AquaVIT-1 intercomparison of atmospheric water vapor measurement techniques was conducted at the aerosol and cloud simulation chamber AIDA (Aerosol Interaction and Dynamics in the Atmosphere) at the Karlsruhe Institute of Technology, Germany, in October 2007.

TL;DR: A multi-platform field measurement campaign involving aircraft and balloons took place over West Africa between 26 July and 25 August 2006, in the frame of the concomitant AMMA Special Observing Period and SCOUT-O3 African tropical activities as discussed by the authors.
