Near-surface smoke refers to the smoke that will hover within 8 meters (26 feet) of the ground—the kind responsible for burning eyes and aggravated asthma.
Vertically integrated smoke depicts all of the smoke in a vertical column, including smoke high in Earth’s atmosphere and can produce red sunrises and sunsets. In some cases where it is only at high altitudes it may not be very noticeable on the ground.

(Information on Wildfire Today about how to reduce your exposure to smoke.)
Below is current information about smoke dispersion across the U.S. and Canada. It is tough to find good, easy to read maps that show concentrations of wildfire smoke across the United States. The backgrounds in some cases obliterate the smoke information or the state boundaries.
If you find a good smoke map, let us know in the comments.
The NOAA webpage with the map below sometimes has smoke data, and sometimes it doesn’t. It also has this, seen today September 14, 2020: “Please note that this web page that you are currently on will be permanently retired on September 7, 2020.” There is a link to a different page, but I was unable to quickly find a substitute map.
The next two maps from AirNow have the same smoke data, but there is a choice of two background maps, terrain or aerial.

Wildfires in the West are producing large quantities of smoke that is severely affecting residents in those areas, but it is also spreading to other states.
Simply staying inside is not enough to protect yourself unless you are aggressively filtering the air with HEPA filters. Outdoor air finds ways to come into your home. If there was no air exchange, you would eventually die as the carbon dioxide levels rose and all of the oxygen was used.
The information below is from AirNow.gov.
