UK SOLAS Chemical and Physical Structure of the Lower Atmosphere of the Tropical Eastern North Atlantic (SLATEA) campaign

The UK SOLAS Chemical and Physical Structure of the Lower Atmosphere of the Tropical Eastern North Atlantic (SLATEA) campaign aimed at investigating the chemical structure of the lowermost atmosphere in remote marine boundary layer regions with high ocean productivity and at quantifying chemical gradients induced at the interfacial region. Fieldwork activities have included participation in the UK SOLAS RHaMBLe cruise (D319), and concurrent aircraft surveys using the NERC Dornier 228 (operated by ARSF) to determine the vertical distribution of reactive trace gases at Cape Verde and near to the RHaMBLe cruise paths. Resulting data have included trace gases such as ozone, carbon monoxide, oxides of nitrogen, halocarbons, and volatile organic compounds (microDiracFMW, TEI 49I UV ozone analyser, Aerolaser AL 5002 fast CO analyser onboard Dornier aircraft) and Fine aerosol particles
