O3 and NO2 satellite observations

The figures below represent daily updated and past satellite data of:

  • NO2 total column (top left) and tropospheric vertical column (top right) time series provided by GOME2 satellite instrument for Thessaloniki, Greece. Blue dots represent this years’ measurements and black, green and red lines the mean, 1 sigma and 2 sigma (calculated from the 2007-last year period), respectively.
  • NO2 total column (middle left) and tropospheric vertical column (middle right) time series provided by GOME2 satellite instrument for Athens, Greece. Blue dots represent this years’ measurements and black, green and red lines the mean, 1 sigma and 2 sigma (calculated from the 2007-last year period), respectively.
  • Total column ozone time series provided by OMI satellite instrument for Athens (bottom left) and Thessaloniki (bottom right), Greece. Blue dots represent this years’ measurements and black, green and red lines the mean, 1 sigma and 2 sigma (calculated from the 2002-last year period and from various satellite sensors), respectively.
