Subject:	OLI/AOS/M1 - Severe storm
DataStreams:	oliaoscpcfM1.b1
Description:	The site lost power during a severe winter storm. Operators on site were not able to get out and restart the generators to bring AOS instrument systems back up until 1/9/2017.
Measurements:	oliaoscpcfM1.b1: nozzle_pressure dilution_slope cabinet_temp condensation_temp liquid_level dilution_flow_reading dilution_correction_factor qc_concentration fraction_full saturation_temp dilution_flow_setpoint time_offset aerosol_flow_calibrated dilution_intercept North latitude(lat) East longitude(lon) Altitude above mean sea level(alt) time optics_temp dilution_valve_position ambient_pressure laser_current base_time orifice_pressure Aerosol concentration averaged over times to match N_CCN(concentration)

Subject:	OLI/CPC/M1 - Instrument Shut Down
DataStreams:	oliaoscpcfM1.b1
Description:	The CPCF and CPCU were shut down while the carbon vane pump that provides flow to the instrument was being repaired.
Measurements:	oliaoscpcfM1.b1: nozzle_pressure dilution_slope cabinet_temp condensation_temp liquid_level dilution_flow_reading dilution_correction_factor qc_concentration fraction_full saturation_temp dilution_flow_setpoint time_offset aerosol_flow_calibrated dilution_intercept North latitude(lat) East longitude(lon) Altitude above mean sea level(alt) time optics_temp dilution_valve_position ambient_pressure laser_current base_time orifice_pressure Aerosol concentration averaged over times to match N_CCN(concentration)

Start Date	Start Time	End Date	End Time	Data Quality Metric
02/09/2017	1737	02/17/2017	2257	Incorrect

Subject:	OLI/AOS/M1 - Instrument Butanol Reservoir contaminated with water
DataStreams:	oliaoscpcfM1.b1
Description:	During this time, the butanol fill reservoir was filled with liquid water instead of butanol. This will affect the ability of the detector to accurately report the aerosol number concentration.
Measurements:	oliaoscpcfM1.b1: fraction_full Aerosol concentration averaged over times to match N_CCN(concentration)

Start Date	Start Time	End Date	End Time	Data Quality Metric
03/06/2017	1847	03/09/2017	2335	Does not affect quality

Subject:	OLI/ALL/M1 - Power Outage
DataStreams:	oliaoscpcfM1.b1
Description:	OLI suffered from a prolonged power outage. The instruments were brought back up over the course of 3/9 so the end date will be different for each instrument. Any problems with the instruments after being brought back online will be covered by separate DQRs.
Measurements:	oliaoscpcfM1.b1: fraction_full qc_concentration saturation_temp nozzle_pressure dilution_flow_setpoint dilution_intercept aerosol_flow_calibrated time_offset dilution_slope cabinet_temp North latitude(lat) East longitude(lon) time Altitude above mean sea level(alt) optics_temp condensation_temp ambient_pressure dilution_valve_position laser_current liquid_level dilution_flow_reading base_time orifice_pressure dilution_correction_factor Aerosol concentration averaged over times to match N_CCN(concentration)

Subject:	OLI/AOS/M1 - Power outage
DataStreams:	oliaoscpcfM1.b1
Description:	During this time the instruments were not collecting data due to a power outage
Measurements:	oliaoscpcfM1.b1: nozzle_pressure dilution_slope cabinet_temp condensation_temp liquid_level dilution_flow_reading dilution_correction_factor qc_concentration fraction_full saturation_temp dilution_flow_setpoint time_offset aerosol_flow_calibrated dilution_intercept North latitude(lat) East longitude(lon) Altitude above mean sea level(alt) time optics_temp dilution_valve_position ambient_pressure laser_current base_time orifice_pressure Aerosol concentration averaged over times to match N_CCN(concentration)
