Weber State balloon project tests air for pollutants - Standard-Examiner
OGDEN — The Weber State clock tower finished chiming at 11 a. m. just after the aerostat made its first float in the outside air, which felt unusually warm for Feb. “Fire up the atmo-sniffer,” said John Sohl, physics professor and HARBOR adviser, wearing a purple Patagonia jacket over a Weber-purple polo shirt. The “atmo-sniffer” is an innovative device, created by Sohl and his students, to measure the muck in Utah’s inversion-prone air up to 1,000 feet. “HARBOR” stands for High Altitude Reconnaissance Balloon for Outreach and Research, a team of students working with Sohl to collect groundbreaking new data on Utah’s inversions. “We’re not really sure what we’re going to find,” Sohl said. “We do know from a few preliminary measurements … (that) when you look at the haze layer, it looks like this uniform ‘ick’ layer, but it’s not uniform. Sohl is the adviser for the HARBOR club, which has flown high-altitude weather balloons for around seven years. With the help of those students, Sohl is working with the Utah Division of Air Quality to get a better grip on the dynamics of inversions along the Wasatch Front, like how pollutants and particles mix in the atmosphere. “We have excellent air monitoring systems on the ground, run by the Utah Division of Air Quality.

Virtual flights, real communications - AOPA Pilot
In the offices of flight simulation software company Mindstar Aviation , Av-Ed Flight School instructor Greg Ashby was acting as air traffic control for the virtual flights of real pilots in the region. Monitoring three flights on a large-screen, radar-like display, he toggled between frequencies giving instructions for landing at and departing the airport, located within the Washington, D. C. , Special Flight Rules Area. Pilots at Internet-connected Redbird simulators in the National Capital Area Flight Simulation Network can now practice their communications skills in a virtual environment created by Mindstar, where pilots may see one another as traffic in the... Seated at the AOPA National Aviation Community Center in Frederick, Maryland, AOPA Aviation Activities Specialist Brenda Tibbs flew a Redbird Jay desktop simulator into the virtual airspace on a Friday to help demonstrate the software. Her groundspeed, squawk code, direction, and N number appeared on Ashby’s screen in Leesburg, where he was able to measure her distance and direction from the Leesburg airport with a drag of a mouse.
