May 9, 1998 was a really bad aerosol day over North America. The Asian smoke pall has arrived to Canada just north of Vancouver - more Asian smoke is approaching the Pacific Coast. The Yucatan/Guatemala fires are still raging and a thick smoke from there has drifted over the Southeastern US. A smoke layer has also blanketed much of Eastern Canada from fires east of the Canadian Rockies. Satellite images show that on Sunday, May 10th, smoke from Asia, Canada, and the Yucatan continued to envelope a substantial area of North America. What kind of a neighborhood is this anyway?
