PANGEA Observatory

PANGEA (i.e. the PANhellenic GEophysical observatory of Antikythera), is the main station of NOA for atmospheric monitoring, aiming to expand in a superstation that will integrate observational facilities and corresponding instruments for the observation of aerosols, clouds and gases following ACTRIS and ICOS standards and definitions. The island of Antikythera in Greece, is located in between the North-west end of Crete and the South of Peloponnese (35.86 Ν, 23.81 Ε, elevation: 110 m a.s.l.). The low altitude of the island, as well as its geographical position, serve as great advantages when it comes to monitoring air masses representative of the Central Mediterranean. Since June 2018 the aerosol remote sensing facility of NOA is operating continuously by the ReACT group, including the sophisticated lidar system PollyXT and the NASA-AERONET sunphotometer.
