Subject: | MAO/UHSAS/S1 - Problem with time fields |
DataStreams: | maoaosuhsasS1.a1 |
Description: | During the MAO deployment the instrument time for the UHSAS was not automatically synched and tended to drift fast relative to the time corrected by a time server. The time of the data in the files is about 0 to 250 seconds fast. This has been determined by comparing the time of spikes in UHSAS CPC data. The discrepancy does not jump around. The time gradually gets faster until it is resynched. The Documents shows the time of the peaks used to approximate the error in the time. During the second time range the UHSAS clock was synced manually each month when the MAO systems were rebooted. The time was generally within 30 seconds of being correct when it was synced. |

Subject: | MAO/AOS/S1 - Flow rate change |
DataStreams: | maoaosuhsasS1.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. |

Description: | The UHSAS was programmed with a bin sizes appropriate to the aerial UHSAS. This is not really a problem. The bin sizes are not consistent with the other console UHSAS. The problem is in blindly comparing the data between the various UHSAS. This is not a problem of mislabeling or incorrect size bins. The data are correct for the stated size bins. |

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 |
