The CHIMERE chemistry-transport model v2020r1 replaces the v2017r5 version and
provides numerous novelties. The most important of these is the online coupling with the …

Simulations are performed for the period 2000–2015 by two different regional climate
models, ALADIN and RegCM, to quantify the direct and semi-direct radiative effects of …

Direct and semi‐direct radiative effects of biomass burning aerosols (BBA) from southern
and central African fires are still widely debated, in particular because climate models have …

Mineral dust emissions mainly depend on soil erodibility and near‐surface wind speeds.
During biomass burning episodes, pyroconvection locally generates high surface wind …

Southern West Africa (SWA) is an African pollution hotspot but a relatively poorly sampled
region of the world. We present an overview of in situ aerosol optical measurements …

Vast stretches of agricultural land in southern and central Africa are burnt between June and
September each year, which releases large quantities of aerosol into the atmosphere. The …

The atypical huge forest fires observed in France during the summer of 2022 are modeled
using the CHIMERE model. The impact of these emissions is quantified on ozone, aerosols …

The formation of a river of smoke crossing southern Africa was investigated during the
Aerosols, Radiation and Clouds in southern Africa (AEROCLO-sA) campaign in September …

Abstract Southern West Africa (SWA) is influenced by large numbers of aerosol particles of
both anthropogenic and natural origins. Anthropogenic aerosol emissions are expected to …

Shortcomings and uncertainties in the model representation of atmospheric transformations
(the aging) of organic aerosol (OA) have long been identified as one of the potential sources …
