What is the role of aerosols in the Namibian fog, and the Namib desert biogeochemistry?

Highlight

5 novembre 2023

Namibia is characterised by some of the most extreme climate regimes ranging from the cold Benguela Current to the hyper-arid coastal deserts of the Namib region. Fog and low-clouds are typical features, affecting the coast and inland up to about 60-100 km, where they have a higher contribution to the total water volume than rainfall, which is very episodic.

In May and September, PEGASUS will be mobilised to Namibia for two new field campaigns 2024 aiming to understand the impact of aerosol particles on the formation and composition of the Namibian fog, the redistribution of nutrients and pollutants, and the sustainability of the regional ecosystems.

The Aerosols and fog in southern Africa: processes and impact on biogeochemistry (AEROFOG) project is is funded by the French ANR and the German DFG, and it is contributed by LISA (FR), LCE (FR), TROPOS (DE), KIT (DE), NWU (RSA), the Gobabeb Namib Research Institute (NAM) and the SANUMARC Research Center (NAM).

The AEROFOG field campaigns in Namibia

The campaigns of the AEROFOG field projects are ongoing: May on the coast, at the Henties Bay campus of the University of Namibia, and September in the Namib desert at the Gobabeb Namib Research Center. PEGASUS is operated jointly with fog collectors and meteorological measurements to understand the role of aerosols in the formation and […]

Off again, direction Namibia

On monday 4 March, PEGASUS has left again to Namibia. A lot of preparatory work and exciting data ahead in the framework of the Aerosols and fog in southern Africa: processes and impact on biogeochemistry (AEROFOG) project. PEGASUS will be operated on the coast, at the Henties Bay campus of the University of Namibia in […]

ACROSS : étudier la chimie atmosphérique dans les milieux forestiers en périphérie de Paris

A l’été 2022, PEGASUS a participé à la campagne de mesure du projet ACROSS (Atmospheric Chemistry of the Suburban Forest) pour étudier les interactions entre les composés chimiques relâchés par les activités urbaines de Paris et les forêts environnantes. PEGASUS était basé sur le super-site dans la forêt de Rambouillet, contribué par le LISA et […]
