Unlike in LA, the smog season in Denver is the winter. The smog is heavily composed of particulates from the gravel used on the streets, believe it or not. Inversion layers are also more common in the winter. Smog alerts are based on visibility measurements rather than on measurements of individual pollutants. This is why wood stoves are a major contributor. Driving is discouraged during alerts so that less gravel will get kicked up. -- ============================================================================== Dean Myerson (aka dingo in boulder) dean@vexcel.com ==============================================================================
