CSU boasts one of world's most advanced radars

Colorado State University this spring installed a unique antenna on one of the nation's most advanced polarimetric weather radars to more precisely detect major storms and precipitation. The new antenna gives scientists a "more delicate knife" to evaluate thunderstorms and the size and distribution of rain, hail and snow, said Steven Rutledge, professor of atmospheric science at Colorado State and the scientific director of the CSU-CHILL radar facility.
The radar, located next to the Greeley-Weld County Airport and known as CSU-CHILL, has the capability of seeing a single hail stone in the atmosphere more than 10 miles away. So-called dual polarization technology will be adopted as the new National Weather Service standard starting next year and deployed on the nation's WSR-88D radars, used to warn the public about developing severe weather. The CSU-CHILL radar supports this effort by developing new techniques that will be used on the weather warning radar network.
The CHILL facility is jointly operated by the Colorado State University departments of Atmospheric Science and Electrical and Computer Engineering. In addition to Rutledge, V.N. Bringi and V. Chandrasekar, professors of electrical engineering, serve as principal investigators on the award from the National Science Foundation, which exceeds $3 million over a three-year period.

It is a great pleasure to announce that Susan C. van den Heever will be joining the Atmospheric Science faculty in August 2008.
Sue received her Ph.D. from the Department of Atmospheric Science at CSU in 2001, after coming to the United States from Johannesburg, South Africa, where she received an M.S. degree from the University of Witwatersrand in 1995. Sue's expertise lies in the areas of cloud and mesoscale dynamics, cloud physics, and NWP models. As many of you know, Sue has been working at CSU since her Ph.D. and has taught ATS 540, Daily Weather Laboratory I, in our department for a number of years.
The hiring of Sue is an outcome of the recent ATS faculty search in the area of mesoscale processes. We thank all of you for your assistance during the search process.
Please join me in welcoming Sue to the ATS faculty!

13-year-old Aboriginal student visits CSU
This past week, the 13-year-old Aboriginal student and his teacher toured NASA's Jet Propulsion Laboratory in Pasadena, Calif., and Colorado State University's Department of Atmospheric Science program in Fort Collins. Neil is a student at Woolaning, a tiny school near Wangi Falls in Litchfield Park that has 10 students and one teacher, Guna Deva. Darwin, a city of 100,000 people, is the closest major city and it's 120 miles away.
Woolaning is part of CloudSat's network of some 70 schools around the world where students observe clouds and cloud behavior and send the data back to CloudSat scientists. CSU, along with JPL and other partners launched CloudSat, the world's first cloud-profiling radar, into space on April 28, 2006. From 438 miles above Earth, CloudSat is giving scientists unprecedented information about the nature of clouds and the amount and type of their precipitation.

CloudSat, a joint project of NASA's Jet Propulsion Laboratory, Colorado State University and other agencies, has received a Rotary National Award for Space Achievement for providing unprecedented perspectives of Earth's clouds.
CloudSat, which is the world's first cloud-profiling radar in orbit, launched on April 28, 2006, and reached a position 438 miles above Earth. The satellite is part of NASA's "A-Train" of Earth observation satellites and one of the very few university-led earth science missions. Graeme Stephens, a University Distinguished Professor of Atmospheric Science at Colorado State University, serves as the principal investigator for the team, which also includes the U.S. Air Force, the U.S. Department of Energy and the Canadian Space Agency. Colorado State's Cooperative Institute for Research in the Atmosphere processes CloudSat data for the scientific community.
The CloudSat team received the award for "exceptional achievement by an international joint government, university and industry team in conceiving, designing, developing and launching the CloudSat spacecraft that provides an unprecedented three-dimensional perspective of Earth's clouds to answer questions about how they form, evolve and affect the weather, climate and fresh water supply."
The Rotary National Award for Space Achievement Foundation Stellar Awards recognize outstanding individuals and teams from industry and government who have made significant contributions to the U.S. space program. The foundation was established in 1985 by the Space Center Rotary Club.

- Russ Schumacher won the 2nd place student oral presentation award at the AMS Weather and Forecasting/Numerical Weather Prediction Conference in Park City, Utah.
- The second Fire Lab At Missoula Experiment (FLAME II) was led by co-PIs Professor Sonia Kreidenweis and Professor Jeffrey Collett from May 21 through June 6 at the USDA/Forest Service Missoula Fire Sciences Laboratory in Missoula, Montana. The primary goal of the FLAME project is to characterize particulate matter emissions from wildland fires relevant to visibility impairment and particulate matter air quality standards. A series of over 100 burns was conducted for a variety of wildland fuels, primarily from the western and southeastern U.S., and measurements were made to develop smoke emission composition profiles and key physical and optical properties of each smoke type. Project findings will support the needs of wildland fire managers and policy makers in determining the contributions of biomass burning to regional air quality degradation. FLAME is supported by the Joint Fire Science Program and is a cooperative effort between the National Park Service, the Forest Service's Missoula Fire Sciences Laboratory, the University of Nevada Desert Research Institute and the Department of Atmospheric Science at Colorado State University, with participation from a number of outside investigators. More information is available here.
