Total Ozone Thickness 2006

jump straight-on to the data

Look here: Intercomparison between the ozone measurements of the Microtops II and those made by the Brewer instrument at the RMI at Uccle and several satellites over the last 8 years.

other near-live or very recent total ozone data:
Thickness of the ozone layer at Uccle Measured by the Royal Meteorological Institute (RMI) of Belgium; shows mean and variance of all data from 1971 on
Ozone Distribution over Europe (NOAA satellite) Ozone map from data measured by the NOAA ( the GOME instrument on the ERS-2 satellite seems to be definitively out of order!)
Northern Hemisphere Ozone Map Ozone map generated from all Northern Hemisphere stations by the WOUDC

The total thickness of the (stratospheric) ozone layer is measured at unspecified, irregular intervals using the handheld Microtops II sensor manufactured by Solar Light Company of Philadelphia. This instrument measures the thickness of the ozone layer by computing the ratios of UVB irradiances measured at three different wavelengths; the water vapour content of the atmosphere and the AOT (aerosol optical thickness) are also measured by the instrument.
The measurement results are given in DU (Dobson Unit). 100 DU correspond to a total thickness of 1 mm, if the ozone layer were at a standard atmospheric pressure of 1013.25 [HPa]. Common values are in the 250..350 DU range.

The previous years dobsonyy.html files and the Microtops measurement files can be found in the data area!

Starting 01 May 2003, the Microtops #3012 has been replaced by a new instrument, serial #5375.
