If anybody knows how to search the USA (or elsewhere) for the place with the highest [*] mixing height, I will give you all of my internet points and sing your praises for the rest of eternity. Here is what the mixing height looks like for a random spot in Washington State: https://forecast.weather.gov/MapClick.php?w3u=1&w13=mhgt&w13u=0&w16u=1&AheadHour=0&Submit=Submit&FcstType=graphical&textField1=46.3578&textField2=-119.0881&site=all&unit=0&dd=&bw= https://forecast.weather.gov/MapClick.php?w3u=1&w13=mhgt&w13... NOAA doesn't seem to publish any data on actual mixing height, and even these forecasted mixing heights are only available for some areas (I can't find them for anyplace in Northern California, for example). I am extremely sensitive to air pollution and this is, by far, the number one factor that correlates with my well-being. You'd think that coastal areas mean "clean ocean air", but they also tend to have very low mixing heights (Los Angeles is an extreme example) so when the wind isn't blowing in from the ocean it's pretty bad. Desert areas have spectacularly high mixing heights during the day, but near zero at night. [*] Technically I'm trying to optimize for the highest height of the lowest Nth percentile (for something like N=5%).
