Abstract:
In this study we have analysed the sensitivity of the erythemally effective radiation to uncertainties in measured total ozone content of the atmosphere (TOC).These uncertainties result from a restricted spatial resolution, a restricted temporal resolution or the restricted accuracy of measured TOC. Daily operational total ozone measurements from different instruments made over several years were applied. Measurements were gained space born by EPTOMS, ERS2/GOME and TOVS and from the ground by Dobson and Brewer Spectrophotometers for the locations of Hradec Kralove (Czech Republic, 50 degrees N), Nairobi (Kenya, I'S) and Springbok (Rep. of South Africa, 30 S). The measurement uncertainties were analyzed by an inter-comparison of modeled erythemally effective UV radiation when using different sources of TOC. The evaluation of the uncertainties due to temporal delays was done in using TOC values with different temporal shifts. The influence of spatial gaps'in TOC measurements was estimated separately in longitude and latitude up to distances of 1000 km around the measuring sites. From this analysis, requirements on the spatial resolution, temporal resolution and measuring uncertainties of total ozone measurements to calculate the erythemally effective UV radiation with a pre-selected accuracy can be derived in dependence of location and season.
