 | New approach improves accuracy of aerosol measurements on cloudy days Satellites taking atmospheric measurements might now be able to see blue skies as clearly as optimists do. Researchers have found a way to reduce cloud-induced glare when satellites measure blue skies on cloudy days, by as much as ten-fold in some cases. The result might lead to more accurate estimates of the amount of sunlight penetrating the atmosphere. Because clouds represent one of the largest areas of uncertainty, eventually this could lead to improved climate models. Sunlight bouncing off clouds blinds satellites trying to determine how much the blue sky between is actually reflecting. ... | ||||
 | Mapping pesticide contamination risk A new computerised tool helps regulators identify water sources at risk of pesticide contamination. The tool can be used to produce maps indicating water bodies at risk of contamination by taking into account: adjacent land-use, the concentration of pesticides in the environment and biological indicators of contamination. Protection of water resources is a key priority for the EU and water bodies located near land used for crop production are at particular risk of contamination from pesticides. The Water Framework directive (WFD)1 sets the objectives for water protection and requires the development ... | ||||
