Environmetrics

Among the aims of OAC there is also monitoring some atmospheric pollution parameters.
There are two main environmetric programs at OAC: monitoring of atmospheric extinction and monitoring of some telluric spectral bands.

 

Monitoring of atmospheric extinction

At OAC we regularly monitor the dust in atmosphere by means of photoelectric measurements of the atmospheric extinction coefficient at various wavelenghts. The effective wavelenghts are those of UBVR photometric system, namely: 360, 440, 550, and 640 nm.
Below we show some examples of Bouguer's lines obtained during nights having fairly high levels of dust in atmosphere.

 




 

Below we show an example of our findings about volcanic ashes in atmosphere.
