AERMOD has replaced ISC in most cases as the preferred air dispersion model for use in PSD/regulatory permitting. AERMOD uses current science to predict the impact of air emissions from multiple sources at receptors located near points of interest. The AERMOD has the ability to use site-specific meteorological parameters to account for variation in wind and stability due to nearby structures, ...
WMO is evaluating the success of a four-year project to improve the provision and use of meteorological information and tools for farmers in West Africa where agriculture and food security is heavily dependent on the weather. The MetAgri Operational Project embraced National Meteorological and Hydrological Services (NMHSs) and farmers and agricultural extension workers in 17 West African ...
Radio frequencies which are vital for weather forecasts, disaster warnings and climate monitoring will remain available to the meteorological community and protected from interference from other applications thanks to decisions taken by the World Radiocommunication Conference 2015 (WRC-15). The World Meteorological Organization (WMO) today welcomed the outcome of WRC-15, which revised and updated ...
A report prepared for the NASA Applied Science Program and authored by economists at The Brattle Groupfinds that the use of NASA's solar and meteorological data services has greatly contributed to the U.S. and international goals of achieving greater energy efficiency and use of renewable energy sources. The study, which was presented today ...

Emissions from domestic wood-fired heaters in southern Tasmania's Huon Valley dwarf emissions from forest regeneration burns, according to a new CSIRO study. "Smoke plume events from prescribed burns do impact the air quality and occasionally exceed the 24-hour standard concentration for particulates but wood-fired heater emissions lead to particulate concentrations that are seven ...
A study of a dozen of 2012's wildest weather events found that man-made global warming increased the likelihood of about half of them, including Superstorm Sandy's devastating surge and the blistering U.S. summer heat. The other half - including a record wet British summer and the U.S. drought last year - simply reflected the random freakiness of weather, researchers with the U.S. National ...
Air quality models have achieved a great degree of sophistication over the last few years thanks mainly to scientific and computational advances. These are tools that simulate the dynamics of the atmosphere and estimate the impact of particular sources of contamination such as industries or traffic on air quality so that plans and decisions can then be made according to the produced results. The ...
The South Eastern Australian Climate Initiative (SEACI) report: Climate variability and change in south-eastern Australia, highlights the effects of climate variability and change on the water resources of the south-east. The SEACI report is a synthesis of findings resulting from the first phase of a collaborative research project between the Australian Department of Climate Change and Energy ...
Daily weather patterns have changed in recent decades, making eastern North America, Europe and western Asia more prone to nastier summer heatwaves that go beyond global warming, a new study finds. A team of climate scientists at Stanford University looked at weather patterns since 1979 and found changes in frequency and strength in parts of the world, according to a study published in the ...
Scientists looking at 16 cases of wild weather around the world last year see the fingerprints of man-made global warming on more than half of them. Researchers found that climate change increased the odds of nine extremes: Heat waves in Australia, Europe, China, Japan and Korea, intense rain in parts of the United States and India, and severe droughts in California and New Zealand. The ...
The impact that human-generated and natural atmospheric particles (aerosols) could be having on Australia’s climate will be discussed next week in Canberra at a workshop involving some of the world’s leading experts in the area. CSIRO Marine and Atmospheric Research scientist, Dr Leon Rotstayn, says the influence aerosols have on climate is still one of the ‘great unknowns’ in climate science. ...
Along with the enormous risks global warming poses for humanity are opportunities to improve public health and build a better world, scientists gathered in Yokohama for a climate change conference said Tuesday. The hundreds of scientists from 100 countries meeting in this Japanese port city are putting finishing touches on a massive report ...
Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change. They are one of the greatest sources of uncertainty in climate change models. ESA's GlobAerosol project has been making the most of European satellite capabilities to monitor them. Using data from the Along Track Scanning Radiometer-2 on the ERS-2 satellite, ...
Using sophisticated unmanned aircraft, research scientists at Scripps Institution of Oceanography, UC San Diego hope to assess Southern California's potential for climate change and better understand the sources of air pollution. Funded by the California Energy Commission, the California AUAV Air Pollution Profiling Study (CAPPS) uses autonomous unmanned aerial vehicles (AUAVs) to gather ...
Many people are understandably perplexed at the U.S.’s recent extreme weather events like record heat waves, torrential downpours, droughts, and wildfires. A ...
Water security is never far from the mind of any decision maker in the U.S. West— but it’s not a terrorist attack on a dam or canal that triggers the most anxiety, it’s climate change. This fall, California Gov. Arnold Schwarzenegger called his state’s water troubles a “holy water war” pitting “north versus south, California versus the feds, rural versus urban....” And well known challenges— the ...
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: ...
The U.S. Environmental Protection Agency (EPA) released a new version of its Community Multi-scale Air Quality model (CMAQ) that uses up-to-the minute meteorology and air chemistry data to determine how weather conditions affect pollution, and how pollution can affect and change weather. Version 5.0 of CMAQ allows scientists to analyze air quality at smaller, finer-resolution settings for ...
