Subject: | MAO/AOS/M1/S1 - Forest Fire |
DataStreams: | maoaospsap3wM1.b1 |
Description: | Smoke from forest burning can be seen on the TSI images rising and then subsequently moving over the site during this period. Many of the AOS instruments observed a sharp spike in data values. October 4-8 multiple fires in the area resulted in hazy conditions during this entire period. Most notable in the following instruments and variables ACSM - Total Organics AETH - Black Carbon Concentrations at all wavelengths CCN100 - Spike in number concentrations occurred a few hours after the smoke plume CLAP3W - Absorption Coefficient CPC - Similar to the CCN100, spike in particle concentration occurred a few hours later CPCF - Particle Concentration CPCU - Particle Concentration NEPHELOMETERS - Scattering/Backscattering Coeff PSAP3W - Absorption Coefficient SMPS - Concentration and Size Distribution UHSAS - Size Distribution |
