Systematic comparison between the ground based automated Dobson of the Observatory of Haute-Provence and TOMS since 1983

摘要

The total ozone quantity has been obtained since September 1983 at O.H.P. using the conventional AD wavelength technique. An average of 180 measurements per year is obtained with the Dobson n deg 85. Each of these daily total quantities is in fact an average of at least 5 measurements. The preliminary comparison with TOMS data show good agreement. We discuss systematic daily and monthly comparisons.
