Subject:	ASI/ACSM/M1 - Data averaging period changed
DataStreams:	asiaosacsmM1.a1
Description:	The data averaging interval was changed from 10 minutes to 30 minutes to conform to standard ACSM collection protocols.
Measurements:	asiaosacsmM1.a1: emission_current vaporizer Mass concentration of sulfate, ambient aerosol in air.(sulfate) inlet_open Mass concentration of ammonium, ambient aerosol in air(ammonium) inlet_closed Mass concentration of chloride, ambient aerosol in air(chloride) Mass concentration of nitrate, ambient aerosol in air.(nitrate) Mass concentration of total organics, ambient aerosol in air.(total_organics) flow_rate base_time

DQRID : D160617.11

Start Date	Start Time	End Date	End Time	Data Quality Metric
06/03/2016	1530	06/13/2016	1221	Suspect

Subject:	ASI/ACSM/M1 - Noisy data from low inlet pressure
DataStreams:	asiaosacsmM1.a1
Description:	The inlet pressure is low as the result of a clogged critical orifice. Data are corrected for inlet pressure but the signal is low because of very light aerosol loading and are noisy.
Measurements:	asiaosacsmM1.a1: emission_current vaporizer Mass concentration of sulfate, ambient aerosol in air.(sulfate) inlet_open Mass concentration of ammonium, ambient aerosol in air(ammonium) inlet_closed Mass concentration of chloride, ambient aerosol in air(chloride) Mass concentration of nitrate, ambient aerosol in air.(nitrate) Mass concentration of total organics, ambient aerosol in air.(total_organics) flow_rate

Start Date	Start Time	End Date	End Time	Data Quality Metric
06/16/2016	0042	06/16/2016	1345	Incorrect

Subject:	ASI/AOS/M1 - Manifold blower not working
DataStreams:	asiaosacsmM1.a1
Description:	Manifold blower not working, instrument sample flows either zero or different than specified. Sampling through the stack not isokinetic.
Measurements:	asiaosacsmM1.a1: East longitude(lon) Mass concentration of ammonium, ambient aerosol in air(ammonium) inlet_closed Mass concentration of chloride, ambient aerosol in air(chloride) Mass concentration of nitrate, ambient aerosol in air.(nitrate) time_offset North latitude(lat) emission_current vaporizer Altitude above mean sea level(alt) Mass concentration of sulfate, ambient aerosol in air.(sulfate) inlet_open time_bounds time Mass concentration of total organics, ambient aerosol in air.(total_organics) base_time flow_rate

10/04/2016	1132	10/04/2016	1623	Suspect

Subject:	ASI/ACSM/M1 - Critical orifice clogged
DataStreams:	asiaosacsmM1.a1
Description:	The critical orifice was clogged during the time period specified. The orifice was cleaned and the instrument placed back in service.
Measurements:	asiaosacsmM1.a1: emission_current vaporizer Mass concentration of sulfate, ambient aerosol in air.(sulfate) inlet_open Mass concentration of ammonium, ambient aerosol in air(ammonium) inlet_closed Mass concentration of chloride, ambient aerosol in air(chloride) Mass concentration of nitrate, ambient aerosol in air.(nitrate) Mass concentration of total organics, ambient aerosol in air.(total_organics) flow_rate
