Effects of clouds and stratospheric ozone depletion on ultraviolet radiation trends
Article Abstract:
The summer average local-noon ultraviolet radiation (UVR) trends responsible for mammalian skin cancer or plant damage will be considerable in the temperate areas by the end of the 20th century due to insufficient cloud cover. The trends in UVR obtained from estimated trends in total ozone availability are compared with the considerable changes in UVR because of changes in cloud opacity. The total ozone abundance and cloud reflectance are obtained from global satellite measurements.

Increased Arctic cloud longwave emissivity associated with pollution from mid-latitudes
Article Abstract:
Arctic climate is particularly sensitive to anthropogenic greenhouse gases and that, over the next century, Arctic surface temperatures are projected to rise at a rate about twice the global mean. The response of Arctic surface temperatures to greenhouse gas thermal emission is modified by Northern Hemisphere synoptic meteorology and local radiative processes and aerosols might play a contributing factor through changes to cloud radiative properties.

A climatologically significant aerosol longwave indirect effect in the Arctic
Article Abstract:
Multisensor radiometric data is used to show that enhanced aerosol concentrations alter the microphysical properties of Arctic clouds, in a process called as the first indirect effect. The cloud amount during the Arctic spring normally exceeds 80% and this implies that the observed longwave enhancement has climatological significance.
