MAO/AOS/M1/S1 - Forest Fire
DataStreams:maoaoscpcM1.a1
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
