Subject:	MAO/SMPS/S1 - clogged impactor at the SMPS aerosol sample inlet
DataStreams:	maoaossmpsS1.a1
Description:	The clogging of the impactor leads to a decrease in the aerosol sample flow rate of the SMPS, which is nominally 1 lpm. This decrease in the SMPS sample flow rate results in an underestimation of the ambient size distribution and integrated number concentration.

Subject:	MAO/SMPS/S1 - Instrument maintenance
DataStreams:	maoaossmpsS1.a1
Description:	A number of instrument maintenance tasks were performed. The flow rate of the system from the impactor was tested. Inlet flow rates and nozzle pressures were examined on the CPC 3772. The accuracy of the classifier voltage and sheath flow rates were evaluated. A HEPA filter zero test was performed. During an approximately 24 hour period, the voltage cable was left unplugged from the classifier.

Subject:	MAO/AOS/S1 - Flow rate change
DataStreams:	maoaossmpsS1.a1
Description:	At begining of period, the bypass blower on MAOS A failed. This was replaced by the instrument operator, but operator was unable to reprogram the PID flow controller. The blower ran approximately 50% faster than designed flow rate. It is unlikely this significantly affected the flow dynamics or transmission efficiencies in the MAOS A sampling stack. The data is colored transparent, but the DQR is filed to alert the user. No specific degradation of signals were noted at this time.

Subject:	MAO/AOS/M1/S1 - Forest Fire
DataStreams:	maoaossmpsS1.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

Subject:	MAO/SMPS/S1 - Insects clogged nafion dryer and SMPS impactor
DataStreams:	maoaossmpsS1.a1
Description:	During this time period the SMPS total concentration was low relative to the cpcf and cpcu concentrations. Upon troubleshooting and examination of components it was discovered that a number of small insects had clogged the nafion dryer and SMPS impactor. The counts may have been lowered due to additional losses from bugs.
