These include 4x4 pick-up trucks with plows and heavy salt capacity.įor major snowstorms, Streets and Sanitation also has the capacity to equip as many as 200 garbage trucks with "quick hitch" plows to supplement the fleet.
LIVE DOPPLER RADAR CHICAGO IL FULL SIZE
While most side streets are cleared by full size Snow Fighting Trucks, Chicago's narrowest side streets are cleaned by a fleet of over 20 smaller plows.
Once arterial streets are patrolled and deemed safe is generally when Snow Command turns our attention to the side streets. The expressway system that travels through Chicago is maintained by the State of Illinois' Department of Transportation, IDOT, and their familiar orange trucks.ĭuring a snow program Streets & Sanitation’s first priority is to clear our main routes and Lake Shore Drive. Our routes consist of city main streets, neighborhood streets and Lake Shore Drive, divided into six Snow Districts.
Once on the roadways our trucks patrol, plow or salt our routes as necessary.ĭSS is responsible for maintaining winter roadway safety on a route system of more than 9,400 lane miles. And we combine all of these technologies along with the Global Positioning Systems (GPS) on all of our trucks to strategically deploy our snow personnel to up to over 280 snow routes. We track incoming weather systems via Doppler radar and through constant communication with our meteorological consultants and the National Weather Service. This high tech command center allows us to access and view a network of cameras and pavement sensors to get a quick and accurate assessment of our pavement conditions citywide. of Streets & Sanitation (DSS) coordinates Chicago's snow and ice control efforts from Snow Command.

This configuration also aids in the ability to gather samples from various polarizations. Each transmitter can individually transmit its respective frequency through its own feed horn onto the 9m offset parabolic antenna. It has a transmitter consisting of both S and X-bands, both using a klystron. Description ĬSU-CHILL is used to study atmospheric principles and precipitation on a small scale with the use of two frequencies. The radar was operated through a cooperative agreement with the National Science Foundation. Colorado State University - CHicago ILLinois radar, colloquially CSU-CHILL, is a semi-mobile, dual-frequency weather surveillance radar developed in 1970 by the University of Chicago and the Illinois State Water Survey, which has since been moved to Colorado on behalf of Colorado State University.
