. Methods a. Data and preprocessing The Iowa Department of Transportation (DOT)’s Motor Vehicle Division maintains a crash database that describes reported motor vehicle accidents in Iowa. Crash data were obtained from the University of Iowa Injury Prevention Research Center (IPRC) for the years 2002–12. The precise location of the crash (latitude, longitude) and the time stamp corresponding to the estimated time of crash were used in this analysis. All crash times were rounded to the nearest hour

is a relatively new venture, for new types of road and atmospheric weather data. DATA COLLECTION. We conducted an Internet survey of U.S. residents during October and November 2010, associated with the American Meteorological Society (AMS) Annual Partnership Topic (APT) focused on mobile observations ( Mahoney and O'Sullivan 2013 ). Prior to sending out the survey, we pretested all questions with several verbal protocol analyses to ensure that questions were being interpreted as planned

obtained by Aerovanc measurements of a meteorological tower showed goodagreement. This method can be ex~ended to obtain a wide-area wind field by dividing the area into smallerones, which is imporiant in underslanding and predicting long-range transporiation of air pollulants.1. Introduction Knowledge of the spatial and temporal variabilityof wind structure in a wide area is required for understanding the long-range transportation of air pollutants. Pollutants emitted from sources in large

1. Introduction Studies by the Federal Aviation Administration’s (FAA’s) observation network have shown that weather is the largest cause of air traffic delays in the national airspace system (NAS), accounting for 69% of all air traffic delays from 2008 to 2013 ( FAA 2017a , b ). Although 80% of flights are on time [ Bureau of Transportation Statistics (BTS) 2017 ], a fraction of the remaining 20% could be delayed because of weather. The FAA defines a delayed flight as one in which an aircraft

quality, spatiotemporal trends and to control and regulate pollutants from different sources to meet the air quality standards in cities across India. As part of this monitoring, continuous monitoring systems that provide data on a near-real-time basis are installed in a number of cities. Data for 91 cities were extracted from the CPCB portal for 1) AQI bulletin ( https://cpcb.nic.in/AQI_Bulletin.php ) and 2) air pollutants and meteorological data ( https

child readers ( Hill 2007 ). While Wilder’s account of the winter was a work of historical fiction, the book contained many verifiable facts, including those regarding the meteorological events of the Hard Winter. Both meteorological records and nonmeteorological accounts indicate that the winter was particularly long, snowy, and cold. Laura Ingalls Wilder (1867–1957) was an American author, writing the Little House book series between 1932 and 1943. Born in Pepin, Wisconsin, to Charles and

1. Introduction The central arctic experiences the most occurrences of blowing snow in Canada, while the Canadian prairies have significant number of events as well ( Phillips 1990 ). Blowing snow can be a hazard to public safety and transportation because of poor visibility associated with some events. An accurate forecast of the occurrence and resultant visibility of this phenomenon may help to mitigate this hazard. Unfortunately, predicting the occurrence of blowing snow and the associated
