| 摘要： | 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. |
