• Abstract:
  On January 29, 2012 at about 4:00 am a thick fog and smoke caused a multiple car ; crash just south of Gainesville, Florida. 11 people were killed and 18 were ; hospitalized. Nationally there are about 38,000 fog related accidents which result in ; about 620 fatalities. Because of the continuous observations of all points within ; Florida, the data from a geostationary satellite was used in which to better ; anticipate the formation of fog along Florida roadways, and to identify fog when it ; does form. The year of 2012 was chosen to examine where fog forms and if it is ; possible to reliably detect fig, It was found that using the difference in two ; frequencies in the infrared spectrum that have difference water absorption ; characteristic, that it was possible to infer the presence of fog. However, many ; non-foggy days also got included. It is though that other discriminates, such as ; wind speed could reduce the false alarm rate.
