Description du jeu de données
RésuméTransport and climatic impact of west-African aerosols; Hygroscopic and radiative properties of the mixing of aerosols (dust, biomass burning, fossil fuel combustion); zoom on organic functions of the carbonaceaous aerosol (formation, transport, aging)
Strategie d'observationDuring intensive observing periods, two spells a day of 2*13 filters will be performed (2 DKT impactors: the first for mineral analysis, the second for carbonaceous analysis). Air sampling with pumps during two periods of some hours (to determine) integrating, firstly, the early morning pollution event and secondly, the afternoon photochemical episode (SOPA, SOPB 2). Continuous measurements of the aerosol distribution between 3nm and 300 nm with the SMPS. During wet season (SOPB 2), continuous measurements of the cloud condensation nuclei number, and of the size distribution at ambient humidity; variability of these size distributions at controled humidity and temperature (D-SMPS). These measurements complete the dataset provided in the frame of the AE_VAN_OR Instrument. Continuous measurements of aerosols extinction with CIMEL microlidar. Continuous measurements of VOC concentrations over both periods.
