Figure 5: Daily columnar ozone amounts from 2003 to 2014 over Athens as have been measured by a Brewer spectroradiometer that is installed at the roof of BRFAA. As can be seen from Figure 5, there is a strong correlation between the ground-based measurements at BRFAA and the satellite observations by OMI of the order of +0.97. Similar correlation also exists between the ground-based observations and the measurements of the European satellite ENVISAT.

Figure 7: Sulfur dioxide (SO2) measured at BRFAA during the forest fires event in August 2009. As can be seen, on August 22-23 total column SO2 was measured to be about three to four times higher than normal.
