AeroMarine, La Réunion. The AeroMarine project was an international collaborative effort between NOAA (USA) and OSU-Réunion and LACy laboratory (France). The Southern Indian Ocean is potentially a hot spot for sea spray emission due to strong trade winds and high sea surface temperature. Hence, measurements taken from La Réunion are relevant for several topics related to marine aerosols and pristine oceanic regions. CSD deployed the POPS (Printed Optical Particle Spectrometer) instrument to La Réunion to observe marine aerosols during a two week field campaign in March 2016. More Info
