San Diego Air Quality Data

The fires are out of the major San Diego metropolitan areas, but the air quality is still bad. The following link provides an hourly update on air pollution - including the 2.5 micron fire-generated particulate matter.

There's alot of data there; look for the "11_PM_2_5 (UG/M3) heading. The data there provide an hourly reading on how much of the 2.5 micron fire-generated particles are still in the air. The ug/m3 means "micrograms per cubic meter".

Google Earth kmz file Overlay

I noticed that the timestamps on the lat/lon points from the Google Earth kmz file were all the same (and stale); I believe that it can only be upadated when the satellite passes overhead (in a polar orbit?). The position data is only valid for infrequent snapshots of fire position.
