OCEANET Atmosphere
New oceanic field campaign on the study of aerosols with mobile photometry

The OCEANET-atmospheric mission from the Alfred Wegener Institute (AWI) aims at measuring atmospheric properties and processes underway from the southern hemisphere, which is less perturbed by human activities, and the more disturbed northern hemisphere. Since about 10 years, the LOA laboratory (Laboratoire d’Optique Atmosphérique), a joint research unit from University of Lille and CNRS is developing new instrumental concept to perform mobile photometry (Karol et al., 2013; Popovici et., 2018).

Recently, with the support of the laboratory of excellence CaPPA, ESA/IDEAS program and CIMEL company, a prototype of a marine version has been developed by SNO PHOTONS (ACTRIS-FR) and setup on board the Polarstern. This instrument provides, similarly to AERONET (autonomous and automatic manner) but for slow exploratory mobile platform, aerosols column integrated properties and water vapor content from sun/sky/moon measurements.

During this campaign, the instrument will sample aerosol properties from Punta Arenas in Chile to Hamburg, Germany.

Data are processed in near real time, as soon as they are transmitted to SNO PHOTONS server located at LOA laboratory.
