Abstract
- UV radiances at the ground and tropospheric aerosols have been retrieved from the TOMS radiance data since 1979. The UV results have shown the global patterns based on ozone and cloud amounts once the latitude and seasonal effects are taken into account. The basic differences in cloud amounts have shown that the southern hemisphere receives much higher UV dosage amounts than corresponding latitudes in the Northern hemisphere. UV trends for the entire globe have been estimated showing that only higher latitudes have shown statistically significant trends. Aerosol distribution have been obtained for the entire globe showing the seasonal dependencies and the changes in specific regions. Most noticeable, have been the changes in dust transport that have occurred in Asia.
