Weather Instrumentation and News from Around the World
The largest and most ambitious tornado study in history will begin next week, as dozens of scientists deploy radars and other ground-based instruments across the Great Plains to gain a better understanding of these often-deadly weather events.
The collaborative international project, involving scientists from the National Centre for Atmospheric Research (NCAR) and a number of other [...]

Located next to the airport on Graciosa Island, the ARM Mobile Facility’s comprehensive and sophisticated instrument suite will obtain atmospheric measurements from the marine boundary layer.
Today marks the beginning of a 20-month field campaign on Graciosa Island in the Azores to study the seasonal life cycle of marine clouds and how they modulate the global [...]

A new array of moored buoys in the Indian Ocean will provide critical climate and ocean data to help scientists predict the dramatic variations between seasonal monsoon rains and droughts.
“The data from these buoys will provide us with much-needed information to advance our understanding of the oceanic and atmospheric processes that [...]

We hear it all the time when someone comes into our weather office: “So, where’s the dartboard?”
It’s actually hidden in our coat closet, but more times than not the games of cricket are just for fun and we base our forecasts off computer model projections.
But computers are never wrong, right? So [...]

Scientists at The University of Arizona will build a prototype instrument to demonstrate their revolutionary idea for a satellite-borne remote sensing system. It will measure water vapor, temperature and ozone anywhere over the globe with unprecedented vertical resolution and accuracy.
This diagram shows how ATOMMS will be mounted in the gimballed ‘X [...]

Changes in the way weather data are collected may have compromised record-keeping and the ability to predict monsoon thunderstorms, according to a National Weather Service veteran and a University of Arizona meteorologist.
The weather service in Tucson used a launch site for [...]
Something odd is happening to the weather along hundreds of miles of bunny fence in Southwestern Australia.
Two scientists from The University of Alabama in Huntsville are part of an international team that will spend August studying why most of the clouds that form in that region form over the native vegetation north and east of [...]
COLUMBUS, Ohio, Oct. 29 (UPI) — U.S. researchers have discovered what might be evidence of the origin of Earth’s breathable atmosphere, similar to the planet’s current oxygen-rich air.
Ohio State University geologists and colleagues said the study suggested upheavals in the Earth’s crust initiated a kind of reverse-greenhouse effect 500 million years ago, cooling the world’s [...]

Climate change models, no matter how powerful, can never give a precise prediction of how greenhouse gases will warm the Earth, according to a new study.
The result will provide ammunition to those who argue not enough is known about global warming to warrant taking action.
The [...]

CUTTING greenhouse gases and switching to sustainable development are unlikely to prevent disasters caused by climate change, one of the world’s respected environmentalists has warned.
Professor James Lovelock, an independent environmental scientist, claims that even the most pessimistic outcomes predicted by the UN’s Intergovernmental Panel on Climate Change fail to recognise [...]
