Friday notes
Criteria pollutants
Primary/secondary (e.g. PANs)
point/non-point sources
fugitive sources-dust (non-point)
IAQ is a serious issue (see LEED and LBC)
Stratospheric Ozone: high altitude
Montreal Protocol: Ozone
Climate change: Kyoto-Copenhagen-Durban (today)
Heat islands, dust domes
Inversion
Surface = hot, altitude is cooler, so there is convective mixing
When surface is cool, stable, no mixing, inversion layer forms (LA, London, Denver, Mexico city)
Acid rain: nitrate or sulfate (see also VOG)
Rain in W. VA was as acidic as stomach acid once
Clean air act 1970 (who was president?)
Bush later ignored this.
