I don’t know about N CA, but in the last week, SoCA has had many ‘clear days, no obvious clouds, but had tremendous haze. I didn’t think much of it, until cleaning air filters and everybody seemed to be coughing more frequently. Very fine particulate matter. Looked more like a geo-engineered haze with particulate matter being sprayed, but not in the obvious ‘chemtrail’ appearance.
No smoke or fires, nor inversion layers, nor sandstorms. Just fine particulate matter.
RE: NorCal - Hard to believe but the other night we had a chem-trail over the top of our smokey hazy sky.
Disgusting program at best.
