THE PIERRE AUGER COLABORATION

In the present study we consider AOD mean data (2010-2013) at high spatial resolution, 1 km x 1 km, (MAIAC-MODIS-Aqua/NASA) over Pierre Auger Observatory, compared with mass concentration [μg /m3] and particle concentration [particle number/litre] of atmospheric aerosols measured in-situ at the observatory.Aerosols concentrations were obtained with Grimm 1.109 instrument for some days in 2016 and 2017.Differents sites were analysed to observe the variation in the aerosol situation across the observatory (horizontal inhomogeneities), by evaluating if there is a correlation between the behaviours of AOD satellite data and in-situ concentration measurements.
