UND STWRC Road Weather Field Research Facility --- I-29 Observations
Observation Times are Local Central Time
Description of the Observational Data
The data on this page come from an instrumented environmental sensor station (ESS) located adjacent and within the south bound lanes of I-29 ... near Buxton, North Dakota or approximately 20 miles south of Grand Forks, North Dakota. This ESS is part of a study being conducted by the University of North Dakota for the North Dakota Department of Transportation on methods to improve the monitoring of road weather conditions using in situ and remote sensing technologies.
The technologies incorporated within the ESS include the use of microwave monitoring of precipitation, precipitation type, and roadway water/ice levels; sonic measurements of wind speed / direction and snow depths adjacent to the roadway; video camera images for monitoring of pavement state; and radiometric monitoring of solar and terrestrial radiation levels.
Data are acquired continuously from the ESS sensors and transmitted in real-time to the Surface Transportation Weather Research Center on the campus of the University of North Dakota. The data are then incorporation into both research and operational activities including the Maintenance Decision Support System in use by the North Dakota Department of Transportation.
