UV spinduliuotės įtaka pažemio ozono lygio formavimuisi
Santrauka
The preliminary analysis of data of ultraviolet radiation and ground-level ozone concentration measurements from the Lithuanian monitoring stations over the years 1998-2003 is presented. Observations showed that an average UV radiation value in January and July of 2002 differed about 10 times. The maximum intensity of UVA radiation was observed in July (about 2,4 W/m2) and minimal in December (0,1 W/m2) the highest UVB radiation intensity was in May (0,09 W/m2), while the minimal UVB radiation value, as well as of UVA, was registered in December (0,07 W/m2). The relationship between the highest ozone concentration and UVB radiation values during summer of the investigation period was found to be linear.
