Unprecedented Arctic Ozone Loss in 2011, Says NASA-Led Study
A NASA-led study has documented an unprecedented depletion of Earth's protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) The study, published online Sunday in the journal Nature, finds the amount of ozone destroyed in the Arctic ...

Satellite data to deliver ‘state-of-the-art’ air quality information
The European Environment Agency has finalised an agreement with an ESA-led consortium to provide unparalleled information on air pollution, which contributes to the premature deaths of hundreds of thousands of Europeans annually. Under the agreement, the European Environment Agency (EEA) will use a service, which combines and processes satellite data with surface measurements from 29 European ...

Street-scale pollution maps for Ireland now available
Results from CERC's modelling of street-scale air pollution in Ireland have been published as part of the Irish Environmental Protection Agency (EPA) report 'Air quality in Ireland 2022'. The full CERC report with high-resolution maps for a wider range of regulated air pollutants is also available. The predicted concentrations were evaluated with measured concentrations with generally good ...

Latest models `could give Asia ten-day flood warnings`
An ensemble of climate and weather simulations could help developing countries better prepare for extreme events such as tropical cyclones, droughts and floods, scientists have said. Many poorer countries rely on traditional weather forecasting techniques, in which an initial set of weather conditions is fed into a single model to predict future adverse events, typically one or two days ahead. ...
