abstract={Weather conditions are natural causes of visibility deterioration and increase in atmospheric extinction coefficient at a place. A 10- year dataset (1998-2007) of visibility and meteorological parameters such as Relative Humidity, Temperature and Atmospheric Pressure measured every 3-hour daily were analysed to examine the dependence of Atmospheric Extinction Coefficient, ¦Â<SUB>ext</SUB> on seasonal meteorological conditions and synoptic weather patterns in Bauchi, a City in the North-eastern-Nigeria. From the visibility data obtained, the corresponding atmospheric extinction coefficient (¦Â<SUB>ext)</SUB> for the period under review was computed by using the Koschmieder relationship. In year 2000, when the Relative Humidity and atmospheric extinction coefficient,<b> ¦Â</b><SUB><b>ext</b></SUB> are highest, the temperature and visibility values are lowest. In 2003, when temperature (29.82¡ãC) is highest, the Relative Humidity (42.52%) is lowest, although, the atmospheric coefficient was not at its lowest neither was the visibility (18.49km) at its highest. Of the years considered, year 2000 has the highest estimated atmospheric extinction coefficient,<b> ¦Â</b><SUB><b>ext</b></SUB> for both raining season and harmattan season. The raining season (June-September) has ¦Â<SUB>ext</SUB> of 0.267 while the harmattan season has ¦Â<SUB>ext</SUB> of 0.689.<b> </b>Their respective decadal mean for both raining season and harmattan season for the period under review are 0.205 ¡À 0.036 and 0.689¡À0.133.},
