The Cap Corse observatory is located in the extreme north of the island in the commune of Ersa. The station is far from sources of anthropogenic pollution and it is surrounded by short vegetation typical of the Mediterranean scrubland. The Ersa station is influenced by long-range atmospheric transport, which include timely air masses originating from the Sahara, and the Rhone valley (France) and industrialized Po in Italy.

The Ersa station was a French contribution to CHARMEX project from the multidisciplinary international program MISTRALS initiated by the CNRS / INSU Atmospheric Chemistry.
