1. The new network configuration is intended to help Characterize the performance of the Brewers and to collect information relevant to quantifying the effects of tropospheric ozone and fine particles on surface UV levels and radiative forcing.

2. 'If we stick to energy production processes, the generation of electrical energy from fossil sources sends out various polluting compounds into the atmosphere, causing global and regional impacts that can be observed in the form of acid raid, climate change, the destruction of the stratospheric ozone layer and contribution to the increase in tropospheric ozone.'
