ChArMEx (the Chemistry-Aerosol Mediterranean Experiment; http://charmex.lsce.ipsl.fr) is part of the international and interdisciplinary meta-programme MISTRALS (Mediterranean Integrated STudies at Regional and Local Scales). Its aim is to assess the present and future state of the atmospheric environment in the Mediterranean Basin, and its impacts on the regional climate, air quality, human health and marine biogeochemistry, in a context of strong regional anthropogenic and climatic pressures. 

BACCHUS (Impact of Biogenic versus Anthropogenic emissions on Clouds and Climate: towards a Holistic UnderStanding; http://www.bacchus-env.eu) is a European FP7 collaborative project under the lead of ETH Zurich, Switzerland. It is one of three individual research projects building the research cluster "Aerosols and Climate" that the EU initiated, recognizing the importance of improving climate predications to develop sustainable policies for Europe. BACCHUS aims at quantifying key processes and feedbacks controlling aerosol-cloud interactions by combining advanced measurements of cloud and aerosol properties with state-of-the-art numerical modelling. 

ACTRIS-2 (Aerosols, Clouds, and Trace gases Research InfraStructure; http://actris2.nilu.no/) is a European H2020 infrastructure project. ACTRIS-2 consolidates and improves services offered within FP7 funded Integrating Activities project ACTRIS (2011-2015). ACTRIS-2 takes up the overarching objectives of ACTRIS to further integrate the European ground-based stations equipped with advanced atmospheric probing instrumentation for aerosols, clouds, and short-lived gas-phase species. ACTRIS-2 represents a fundamental step towards the establishment of the atmospheric component of the Integrated European Observing System and a clear upgrade in services offered to users. 

FEMRC (Future Earth MENA Regional Center; http://www.futureearth.org/) is one of the Regional Centers in the framework of the central secretariat of Future Earth with responsibilities for countries in the Middle East and North Africa (the MENA region). 

iLEAPS (Integrated Land Ecosystem-Atmosphere Processes Study; http://www.futureearth.org/projects/ileaps-integrated-land-ecosystem-atmosphere-processes-study) is one of the core projects of Future Earth. iLEAPS aims to enhance the understanding of how interacting biological, chemical and physical processes transport energy and matter through the land – atmosphere interface at all scales from past to future and local to global, with particular emphasis on the human influence on these processes.
