2 to the full AWIPS real-time meteorological data and can serve a number of clients who are either collaborating or working independently. Dual servers are implemented to provide the necessary redundancy. For the initial prototype, the servers reside at the NOAA/ESRL Global Systems Divi- sion (GSD) computer facility. The GTAS client software can be downloaded from a local server and installed on a remote client using a simple installation script. A single remote client was installed at the FEMA office in the Washington, D.C. area and several clients were configured at GSD in Boulder. Thus far, the system has only been used to demonstrate the basic GTAS concept. FEMA staff has been able to simulate a toxic release and initialize the dispersion model. Separate tests have been conducted to draw warning polygons and send the coordinates to two reverse-911 vendors – 21st Century and Intrado, Inc. Figure 3 illustrates a dispersion plume in the Washington, D.C. area using a simulated release point and agent. For the initial prototype, the HySPLIT model is initialized using the NAM-12 grids.

Other changes include new handi- cap openers on our entry doors, new sinks and cabinets in the restrooms, a new chaise lounge in one restroom, new entry floor mats, and most conspicuous of all, a new counter top, all new conference tables and chairs, and a new wireless conference phone in our Director’s Conference Room.

Vonder Haar Celebrates 100th Student Since his arrival at Colorado State University in 1970, Dr. Tom Vonder Haar has enjoyed advising and mentoring more than 100 students to receive more than 100 degrees, including 76 M.S. and 27 Ph.D.s. Of course, some students obtain both the M.S. and Ph.D. in atmospheric science at CSU, so the question in the hallway has always been “Who will be Professor Vonder Haar’s 100th student to graduate?” The counting began easily with Tom’s first M.S. student (Capt. Gerry Sikula, 1971) and Ph.D. (Dr. Jim Ellis, 1975). Then, with co-advising of some and a few M.S. students taking the non- thesis option, the counting became a bit fuzzy. By combining the department records provided by Jen Weingardt, the Vonder Haar research group records compiled by Holli Knutson and Tom’s own count, it has been determined that his 100th student graduate ( ± 1 or 2) is among a group of four M.S. advisees that completed their degrees in Fall-Winter 2006. They are: Kate Maclay, Becca Mazur, Kevin Donofrio, and Dustin Rapp. Tom hosted a good sized group at his “100th student/graduate” lunch!

For example: Source: NEETF & Roper, 2001[1] • Only 27 percent of Americans know that 60 percent of our electricity is produced by burn- ing coal and other flammable materials. 40 percent of people believe that hydroelectric power is America’s top source of energy (only 10 percent of the total) • Add up hydropower, nuclear, and solar sources, and the majority of Americans think our elec- tricity is generated in ways that have little or no impact on air quality • Just 22 percent of Americans know that run- off from farm fields, roads, parking lots, and lawns is the leading cause of water pollution in America today. 47 percent think the most common form is waste dumped by factories • 120 million Americans believe spray cans still have CFCs in them even though CFCs were banned in 1978

• 45 million Americans think the ocean is a source of fresh water • One in four Americans (23 percent) knows that paper products are the number one source of landfill material in America. 29 percent still think that disposable diapers are the greatest cause of over-stuffed landfills • Two-thirds of Americans fail to recognize that the transportation sector is the largest petro- leum user in the U.S. These facts and figures point to the need for comprehensive environmental education. While the American public continues to engage in basic activities (recycling, conserving electricity, and saving water) to benefit the environment, they are not embracing the fact that the lion’s share of our pollutants is generated by individuals and small entities.

International Polar Year Expedition to the South Pole, Antarctica Dr. Glen E. Liston and Dr. Jan-Gunnar Winther Diary Excerpt (Glen), 1 December 2007 As I lie in my small tent at -48 °C (-54 °F) near the center of Antarctica, I try to mentally force my near-frozen toes back to life. The temperatures I am experiencing now are just about equal to the mean annual Antarctic air temperature in this area; something that typically changes only slowly over the decades and centuries. I also note that one month ago I was flying, uncontrolled, 15 meters (50 feet) through the air in response to a 52 m/s (132 mph) wind gust during a storm near the Antarctic coast. I am part of a scientific research expedition traversing from the Antarctic coast to the South Pole, and this is exactly what we are here to study and understand: weather and climate variability and change on time scales of 1000 seconds (like my wind-borne flight) to 1000 years (like my cold, cold night).

29 CIRA Mission The mission of the Institute is to conduct research in the atmospheric sciences of mutual benefit to NOAA, the University, the state, and the nation. The Institute strives to provide a center for cooperation in specified research program areas by scientists, staff, and students and to enhance the training of atmospheric scien- tists. Special effort is directed toward the transition of research results into practi- cal applications in the weather and climate areas. In addition, multidisciplinary research programs are emphasized, and all university and NOAA organizational elements are invited to participate in CIRA’s atmospheric research programs. The Institute’s research is concentrated in several theme areas that include global and regional climate, local and mesoscale weather forecasting and evaluation, applied cloud physics, applications of satellite observations, air quality and visibil- ity, and societal and economic impacts, along with cross-cutting research areas of numerical modeling and education, training, and outreach. In addition to CIRA’s relationship with NOAA, the National Park Service also has an ongoing coopera- tion in air quality and visibility research that involves scientists from numerous disciplines, and the Center for Geosciences/Atmospheric Research based at CIRA is a long-term program sponsored by the Department of Defense.
