But CN Doors is no ordinary small town garage door installation and service company. Based out of Yellowknife in the Northwest Territories (NWT) of Canada and servicing neighboring Nunavut, CN Doors services a geographical area of 1.3 million square miles – equal in size to ½ the contiguous 48 US States. Launched in 2004, the company is, according to Colin Cleveland, Operations Manager and co-owner of CN Doors, a specialist in servicing the arctic market. “Our tech guys routinely fly in with the Ice Pilots of Buffalo Air and drive the same ice roads as the Ice Road Truckers,” notes Cleveland.

ESSENTIALS of METEOROLOGY (7Th Ed.) GLOSSARY
ESSENTIALS OF METEOROLOGY (7th ed.) GLOSSARY Chapter 1 Aerosols Tiny suspended solid particles (dust, smoke, etc.) or liquid droplets that enter the atmosphere from either natural or human (anthropogenic) sources, such as the burning of fossil fuels. Sulfur-containing fossil fuels, such as coal, produce sulfate aerosols. Air density The ratio of the mass of a substance to the volume occupied by it. Air density is usually expressed as g/cm3 or kg/m3. Also See Density. Air pressure The pressure exerted by the mass of air above a given point, usually expressed in millibars (mb), inches of (atmospheric mercury (Hg) or in hectopascals (hPa). pressure) Atmosphere The envelope of gases that surround a planet and are held to it by the planet's gravitational attraction. The earth's atmosphere is mainly nitrogen and oxygen. Carbon dioxide (CO2) A colorless, odorless gas whose concentration is about 0.039 percent (390 ppm) in a volume of air near sea level. It is a selective absorber of infrared radiation and, consequently, it is important in the earth's atmospheric greenhouse effect. Solid CO2 is called dry ice. Climate The accumulation of daily and seasonal weather events over a long period of time. Front The transition zone between two distinct air masses. Hurricane A tropical cyclone having winds in excess of 64 knots (74 mi/hr). Ionosphere An electrified region of the upper atmosphere where fairly large concentrations of ions and free electrons exist. Lapse rate The rate at which an atmospheric variable (usually temperature) decreases with height. (See Environmental lapse rate.) Mesosphere The atmospheric layer between the stratosphere and the thermosphere. -
Detection of Glaze Icing Load and Temperature of Composite Insulators Using Fiber Bragg Grating

To solve this issue, a novel method is first proposed to detect glaze icing load via embedding three optical fibers with fiber Bragg gratings (FBGs) into a 10 kV composite insulator. Specifically, FBG temperature compensation sensors were packaged in ceramic tubes to solve strain and temperature cross-sensitivity. Temperature effect experiments and simulated glaze icing load experiments were performed to verify the feasibility of the proposed method. The results show that temperature sensitivities of all FBGs are identical (i.e., 10.68 pm/◦C), which achieves a simultaneous measurement of temperature and strain. In addition, the proposed method can detect glaze icing load of the composite insulator above 0.5 N (i.e., 15% of icicle bridged degree) in the laboratory.

Road Weather Condition Estimation Using Fixed and Mobile Based Cameras
Road Weather Condition Estimation Using Fixed and Mobile Based Cameras Koray Ozcan1(&), Anuj Sharma1(&), Skylar Knickerbocker2(&), Jennifer Merickel3(&), Neal Hawkins2(&), and Matthew Rizzo3(&) 1 Institute for Transportation, Iowa State University, Ames, IA, USA {koray6,anujs}@iastate.edu 2 Center for Transportation Research and Education, Ames, IA, USA {sknick,hawkins}@iastate.edu 3 University of Nebraska Medical Center, Omaha, NE, USA {jennifer.merickel,matthew.rizzo}@unmc.edu Abstract. Automated interpretation and understanding of the driving environment using image processing is a challenging task, as most current vision-based systems are not designed to work in dynamically-changing and naturalistic real-world settings. For instance, road weather condition classifica- tion using a camera is a challenge due to high variance in weather, road layout, and illumination conditions. Most transportation agencies, within the U.S., have deployed some cameras for operational awareness. Given that weather related crashes constitute 22% of all vehicle crashes and 16% of crash fatalities, this study proposes using these same cameras as a source for estimating roadway surface condition. The developed model is focused on three road surface con- ditions resulting from weather including: Clear (clear/dry), Rainy-Wet (rainy/slushy/wet), and Snow (snow-covered/partially snow-covered). The camera sources evaluated are both fixed Closed-circuit Television (CCTV) and mobile (snow plow dash-cam). The results are promising; with an achieved 98.57% and 77.32% road weather classification accuracy for CCTV and mobile cameras, respectively. Proposed classification method is suitable for autono- mous selection of snow plow routes and verification of extreme road conditions on roadways. -
