The Laboratory of Atmospheric Pollution is part of the Department of Environmental Engineering, of Democritus University of Thrace in Greece. The laboratory closely collaborates with other Atmospheric Physics and Meteorology Departments in the country and in Europe via national, international and EU funded programmes.
Scientific aims
The determination of atmospheric pollution levels in cities and rural environments.
Transboundary atmospheric pollution loads.
Greenhouse gases relation to global and local climatology
Aerosol optical and chemical properties and their relation to direct and indirect climate forcing
Study of Indoor Air Quality problems and the effect of indoor atmospheric pollutants on works of art and human health.
IAQ modelling & management.
Occupational safety and health issues and industrial hygiene problems.
Biogeochemistry
Remote sensing
Large scale facilities
I. The laboratory has instrumented and operates the only Greek aircraft for airborne research, associated also with the European Fleet for Airborne Research, with the characteristics “AEROFOTO-DUTH” (www.eufar.org).
II. It operates the 125 m flux tower at the old Voice of America station (VOCALS), 40° 53' 22.47" N 24° 51' 00.43" E, determining fluxes of Greenhouse gases and Mercury. http://www.europe-fluxdata.eu/home/sites-list
