Abstract. Maps of solar erythemal ultraviolet (EUV) irradiance
daily doses were created for every month with a horizontal
resolution of 500 m at the geographical domain 47.15 N–49.86 N×16.94 E–22.81 E covering the territory of
Slovakia. The cloud modification factor for the EUV radiation (cmfUV)
was modeled utilizing the relation between the cloud modification
factor of global and EUV radiation.
The maps of the cmfUV factor were created by utilizing measurements
of global irradiance performed at nine observatories
during the period 1995–2004 and modeling of the cmfUV dependence on altitude.
Maps of the EUV irradiance daily dose corresponded to clear-sky conditions and EUV irradiance daily dose affected by average
cloudiness were constructed for mean monthly total
ozone, its upper and lower monthly limits, for two probability
levels of snow cover occurrence as criteria for the
snow effect incorporation in the model and for one day representing
typical values for every month. The map-set can be regarded as an atlas of solar EUV radiation over Slovakia.
