Bay Area AM radio 9-9-2020

[e-dawg]

With all the Orange sky coming from the wildfires and the daylight turns into night around noon. Especially my street lights been on all day. Have anybody check to see if they hear distance AM stations in the bay area today such as Los Angeles, Portland, or Seattle? Does the hazy and dark air effects the AM propagation when it comes to ground waves and sky waves? I remember when I was up in Portland back in 2017 during the solar eclipse. I can hear KGO 810 and KOMO 1000 clearly during total solar eclipse up in Portland.

No, it doesn't

AM propagates via skywave by reflecting from layers of the ionisphere that are well above the height of the smoke. It has nothing to do with smog or smoke.

The ionosphere, where reflection occurs, begins at about 80 km above the earth's surface.

A solar eclipse is different from smoke in the lower atmosphere, because an eclipse darkens the ionosphere -- smoke doesn't. Smoke doesn't reach high enough to darken the ionosphere.
