Subject:	OLI/AOS/M1 - Severe storm
DataStreams:	oliaosuhsasM1.a1
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:	oliaosuhsasM1.a1: base_time lower_size_limit Temperature at the ground station(temperature) upper_size_limit current flow East longitude(lon) time_offset sample_pressure North latitude(lat) sampling_volume unit_temperature Altitude above mean sea level(alt) Particle size distribution, limited by lower_size_limit and upper_size_limit(size_distribution) bin_num purge_flow reference auxiliary differential_voltage sheath_flow time scattering_voltage

Subject:	OLI/UHSAS/M1 - Inlet plumbing issues
DataStreams:	oliaosuhsasM1.a1
Description:	Plumbing issues with the UHSAS sample line. Instrument working fine, but likely not sampling ambient air directly.
Measurements:	oliaosuhsasM1.a1: lower_size_limit Temperature at the ground station(temperature) upper_size_limit flow current sample_pressure sampling_volume unit_temperature Particle size distribution, limited by lower_size_limit and upper_size_limit(size_distribution) bin_num purge_flow reference auxiliary differential_voltage sheath_flow scattering_voltage

Subject:	OLI/ALL/M1 - Power Outage
DataStreams:	oliaosuhsasM1.a1
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:	oliaosuhsasM1.a1: base_time lower_size_limit upper_size_limit Temperature at the ground station(temperature) current flow East longitude(lon) time_offset sample_pressure North latitude(lat) unit_temperature sampling_volume Altitude above mean sea level(alt) Particle size distribution, limited by lower_size_limit and upper_size_limit(size_distribution) bin_num purge_flow auxiliary reference sheath_flow differential_voltage time scattering_voltage

Subject:	OLI/UHSAS/M1 - Contamination in the optics chamber
DataStreams:	oliaosuhsasM1.a1
Description:	Something stuck to the inlet jet nozzle causing high counts in the lower size bins. Other size bins also potentially affected. Some data missing as the instrument went into safe mode.
