A MAXDOAS instrument was installed at the University of Crete building in Heraklion in August 2007. This instrument performs zenith-sky observations and in addition looks towards the horizon over the close-by Mediterranean. This BREDOM site is operated in co-operation with the Environmental Chemical Processes Laboratory at the Department of Chemistry, University of Crete, Greece.
Heraklion (35.3°N, 25°E) is often influenced by local pollution, but also experiences periods of background air and import of pollution from mainland Greece. It has strong illumination and high temperatures in summer and is a location with high photochemical activity.
The instrument in Heraklion consists of two grating spectrometers, one for the UV (325 - 405 nm), the second one for the visible spectral range (390 - 555 nm). Both spectrometers are equipped with cooled CCD detectors and are temperature stabilized to minimize spectral drift. The set-up is equipped with a MAXDOAS telescope to observe both the horizon and the zenith-sky. More on the instrument and measurement principle can be found on our MAXDOAS page.
