There are three (S1E1W1) and will give a fairly good representation of the number of particulates in the area. The baseline fluctuates somewhat, and the shutdown numbers are yet to be determined. The default is PM2.5 EPA AQI and should check other methods if the number is over 50-100 (needs calibration). Please find the map at the following link: |

| Gauging the airborne dust and pollen can be problematic because you need a bright light and a relatively dark night. In general, you want to look in the bottom 0.5 meter of the light column. There will be a diffuse column lit up by the beam – don’t worry about it, just follow the dust glints. If you can count the dust glints, the conditions are safe to observe. If it looks like a blizzard, close up. If any of the dust glints shine with an orange or a peach hue, or the dust glints look abnormally large, the dust is probably ash – close up immediately. Ash seriously degrades bare aluminum coatings. Dust and wind go together. But, just because it is calm, the dust conditions might still be bad. If it was windy a few days earlier, it could have kicked up a lot of dust, which can take several days to settle. Finally, during late spring to early summer, conifer tree pollen can be problematic. If particulates are borderline please email the CHARA day staff so they can clean the optics as soon as possible. | Gauging the airborne dust and pollen can be problematic because you need a bright light and a relatively dark night.
