At the beginning of the week, emissions from the large forest fires were transport southward by a rapid northerly current between a high west of the Great Lakes and a low on the east coast of Canada.

The satellite image from Wnesday, June 7th shows the extent of the forest fire aerosols. While large parts of the province of Quebec are obscur by clouds (white), the huge plume of smoke can be seen south of Toronto to New York. (earthobservatory.nasa.gov)
Accordingly, visibility in New York was also significantly russia phone number library impair by the smoke aerosols.

Carbon monoxide as a good tracer
Carbon monoxide (CO) is a good indicator of the transport of forest fire emissions, because CO has a lifetime of several weeks in the atmosphere and can therefore travel thousands of kilometers, sometimes even from one continent to another. CO is the product of incomplete combustion and has various sources, although emissions from forest fires can be the largest. (Source: Copernicus).

Current situation in Canada
Although the current low pressure system is bringing some the fear could concern the reliability of your company rainfall, the situation has not yet eas. All fires mark in r are not yet under control. The dark blue awb directory symbols, which are mainly found in the eastern regions, indicate fires that are currently being actively fought by the “Société de protection des forets contre le feu” (SOPFEU). Light blue symbols indicate forest fires that are completely under control. The figure shows the approximate size of Switzerland for context.
