Levels of carbon dioxide in the atmosphere are fluctuating more than they used to from one season to another, according to observations from the HIPPO field project. This may be a sign of significant changes in northern ecosystems.
They’ve been carried by truck into supercell thunderstorms, flown on aircraft into hurricanes, and sliced and diced the atmosphere in myriad ways. Where are research radars headed next, and where will they take science and society?
Scientists are analyzing results from a project that pulled together chemists, radar experts, cloud physicists, forecasters, pilots, and other specialists to investigate the evolution of thunderstorms.
States are having to make tough decisions regarding their water use and their interaction with water. NCAR scientists are involved in collaborative projects in Colorado, Louisiana, and Oklahoma to evaluate the long-term effects of today’s decisions.
A small, sophisticated instrument package developed at NCAR and dropped from aircraft has led to notable improvements in hurricane prediction. Now these devices are poised to deliver more data than ever, thanks to a new design and a remotely piloted NASA aircraft.
A multisatellite observing system that was only a gleam in researchers’ eyes in the 1990s is now a key tool for monitoring Earth’s atmosphere. An ambitious follow-up project could yield up to ten times the data gathered by the current satellites.
Thanks to deicing treatment and careful route selection, commercial pilots now avoid most of the threat that ice will encase critical parts of a plane. But another, more mysterious kind of in-flight icing hazard is now gaining attention.
Amid day-to-day weather forecasts and seasonal outlooks, there's a no-man's-zone of uncertainty one to two months out. A phenomenon called the Madden-Julian Oscillation may hold the key to better predictions in this intermediate period.
The governor will present the annual awards for “High Impact Research” on November 15 to teams from the National Center for Atmospheric Research (NCAR) and three other Colorado-based research centers for scientific breakthroughs.
A balloon-borne instrument sailing in the Arctic stratosphere in June obtained some of the best observations to date on the high-speed, Sun-driven winds that howl through the thermosphere more than 100 kilometers (60 miles) above Earth.
Prior to massive flooding early in 2011, long-term drought plagued the Australian state of Queensland . As part of a broad research program on cloud seeding, NCAR researchers have been steadily crunching data from a 2008–09 field project that looked into how to make the clouds drop more rain on the region.
The surfeit of snowfalls across the U.S. East Coast over the last two winters brought ample evidence of just how much the white stuff can vary from place to place—and how difficult it is to assess accurately.
