Abstract:
Beside the sun elevation angle. the total ozone content (TOC) of the atmosphere is a main input parameter of models to predict the biologically-effective UV radiation. Therefor TOC was analyzed for the domain of Central Europe. The data domain contains the area from 7degreesE to 17degreesE in longitude and from 45degreesN to 50degreesN in latitude. Ground based as well as satellite based measurements from EPTOMS were involved. The temporal and spatial variability of TOC was analyzed using auto-correlation and fitting auto-correlation functions. It becomes evident that temporal correlation decrease rapid within the first 9 days down to the level of l/e. From spatial correlation functions de-correlation distances (l/e) arc estimated with 180 kin E-W and 145 km for S-N direction. The analysis of TOC variability per 100km for the domain of Central Europe was also examined. The results show that the highest values can reach up to 18%/100km. Day-to-Day variability for a certain location may exceed this level by a few percent (25%/day). These results show that for the calculation of the biologically effective UV radiation a high spatial resolution of TOC data is necessary to ensure an appropriate quality.
