Long-term changes of the ozone layer over the Czech Republic
In 2010 the long-term monitoring of the ozone layer over the Czech Republic (CR) reached 50 years of its realization. Total ozone (thickness of the ozone layer) has been measured by the Dobson D074 (since 1961) and the Brewer (B098 since 1994 and B184 since 2004) spectrophotometers (Fig. 2, 3) at the Solar and Ozone Observatory (SOO, Fig. 1) of the Czech Hydrometeorological Institute (CHMI) in Hradec Kralové. Measurements of vertical profiles of ozone concentrations have been performed since 1982 by the balloon-born electro-chemical ozone sondes (Fig. 4) at the Aerological Observatory (AO) of CHMI in Praha-Libus. Since 2005 vertical ozone distribution has been measured also by the Brewer-Umkehr method at SOO. The observatories contribute to the international ozone monitoring programmes, mainly to the Global Atmosphere Watch (GAW) and to the Network for Detection of Atmospheric Composition Change (NDACC).
The data sets originated at SOO and AO are deposited into the World Ozone and UV data center, Toronto, Canada. Because of their size and quality they allow to make a comprehensive analysis of evolution of the ozone layer over the region of Central Europe in the recent five decades and to estimate its further changes with the aim to expected ozone recovery in NH mid latitudes. These were the main goals of a scientific study that was supported by the project P209/10/0058 of the Czech Grant Agency.<br>This study presents scientific outputs of the project P209/10/0058 that was closely tied to previous national and international ozone-related projects realized in CHMI.
