Are aerosols reducing coastal drizzle and increasing cloud cover?
Scientists sponsored by the Department of Energy are conducting a six-month atmospheric research campaign at the Point Reyes National Seashore, in Marin County, California. The experiment's goal is to help researchers understand how aerosols -small particles such as soot, dust and smoke-influence the structure of marine stratus clouds, and how... view more...

Advances in nebulised drug delivery
AROUND £50 million of National Health Service money a year is spent nebulising drug aerosols to patients with asthma, cystic fibrosis and infections. Drug delivery by this route currently escapes attention from the regulatory authorities because the drug is sold separately from the delivery device and clinical practice is based largely on... view more...

Inside the Ozone Layer
A new atmospheric model is able to quantify man-made versus naturally occurring damage to the stratosphere with an eye toward repairing the diminishing ozone layer that is located within the stratosphere. view more (2006-02-24)
Aerosol toxins from red tides may cause long-term health threat
NOAA scientists reported in the current issue of the journal Environmental Health Perspectives that an algal toxin commonly inhaled in sea spray, attacks and damages DNA in the lungs of laboratory rats. view more (2008-07-10)
Tracking Down the Menace in Mexico City Smog
A new report by scientists who are part of the international MILAGRO Campaign indicates that some of the most harmful air pollution in Mexico City may not come from motor vehicles but instead originates with industrial sources - and that the culprit may be garbage incineration. view more (2008-09-08)
The greenhouse gas that saved the world
When Planet Earth was just cooling down from its fiery creation, the sun was faint and young. So faint that it should not have been able to keep the oceans of earth from freezing. But fortunately for the creation of life, water was kept liquid on our young planet. view more (2009-08-18)
UCSD researchers make first direct observations of biological particles in high-altitude ice clouds
A team of UC San Diego-led atmospheric chemistry researchers moved closer to what is considered the "holy grail" of climate change science when it made the first-ever direct detection of biological particles within ice clouds. view more (2009-05-18)
Three ESA satellites reveal Etna's complexity
As detected by ESA satellite sensors, the recent eruptions of the Mount Etna volcano in Sicily are throwing huge amounts of ash and trace gases into the atmosphere. Working with data from the Global Ozone Monitoring Experiment (GOME) sensor onboard ESA's ERS-2 spacecraft, scientists at the German aerospace centre (DLR) report that levels of... view more...

UNH Scientists Continue To Fly High As NASA Unlocks The Puzzle Of Global Air Quality
The National Aeronautic and Space Administration's (NASA) DC-8 research aircraft is arguably the world's most sophisticated flying laboratory and scientists from the University of New Hampshire have been onboard the jet conducting one-of-a-kind science for the past two decades. view more (2006-04-28)
New technology may help Olympic sailing
A team of researchers at the Ocean University of China has developed and tested a mobile lidar (light detection and ranging) station that can accurately measure wind speed and direction over large areas in real time -- an application useful for aviation safety, weather forecasting and sports. view more (2008-07-01)
Mobile climate monitoring facility to sample skies in Africa
The U.S. Department of Energy's Atmospheric Radiation Measurement (ARM) Program is placing a new, portable atmospheric laboratory with sophisticated instruments and data systems in Niger, Africa, to gain a better understanding of the potential impacts of Saharan dust on global climate. view more (2006-01-19)
Cities incite thunderstorms, researchers find
Summer thunderstorms become much more fierce when they collide with a city than they would otherwise be in the open countryside, according to research led by Princeton engineers. view more (2007-08-10)
ESA to select new Earth Explorer missions
An important milestone for ESA's Living Planet Programme is to be reached this spring when it will be decided which of the six candidate Earth Explorer missions are to be selected for development. Before decisions are taken, the user community is invited to express their views at the Earth Explorer User Consultation Meeting which will be held on... view more... (2004-02-05)

Historic volcanic eruption shrunk the mighty Nile River
Volcanic eruptions in high latitudes can greatly alter climate and distant river flows, including the Nile, according to a recent study funded in part by NASA. view more (2006-11-22)
Pollution shown cutting rainfall in hilly areas
Manmade climate change due to pollution seriously inhibits precipitation over hills in semi-arid regions, a phenomenon with dire consequences for water resources in the Middle east and many other parts of the world. view more (2007-03-09)
Rain showers may be caused by vortices in the air
The Delft researchers calculated how hundreds of thousands of water droplets contained in about one litre of cloud move and grow. During this process, it would seem that tubular-shaped vortices a few centimetres in size are formed and that these force the droplets outwards by centrifugal force, so that they congregate at the edge. For rain to be... view more... (1999-11-09)
Human activities in arid urban environments can affect rainfall and water cycle
In the past half-century, cities have begun to expand in some of the Earth's most arid areas. While scientists have known for some time that the so-called "heat-island" effect of large cities such as Atlanta and Houston can affect their weather, they knew less about this effect and other processes in arid cities, such as Phoenix, which... view more...

Rutgers/EOHSI Builds Model to Assess World Trade Center Fallout
The environmental and health consequences of the terrorist attacks on the World Trade Center have been the subject of controversy almost from the beginning. Scientists at Rutgers, The State University of New Jersey, have created a computerized model that will help public health officials understand the degree of harmful exposure in the immediate... view more...

NASA study: Alaskan fires affected Houston air quality in 2004
An innovative new NASA-funded study based on a combination of satellite data, computer models and weather balloon readings finds that smoke from Alaskan and Canadian forest fires as much as doubled ground-level ozone thousands of miles away in Houston during a two-day period in July 2004. view more (2006-09-22)
