Measured particle extinction at 532 nm outside of Estes Park, CO shown as 1 minute averages. Note the low levels of ambient particle extinction. The spikes are particulate emissions from passing vehicles. 250200150100500Extinction (Mm-1) 5/21/10 5/31/10 6/10/10= 630 nmPasadena, CAADVANTAGES:• Choice of 1 of 3 Wavelengths: Red (630 nm) Green (525 nm) Blue (450 nm)• No calibration required.• Autonomous Operation: No Zero Air.
