Subject:	SGP/ACSM/C1 - Filter switching valve not operating
DataStreams:	sgpaosacsmC1.b1, sgpaosacsmC1.a1
Description:	Filter switching valve was not operating because of a faulty circuit board. Problem was fixed and data have been collected from the end of the specified time period.
Measurements:	sgpaosacsmC1.a1: flow_rate vaporizer inlet_closed Mass concentration of chloride, ambient aerosol in air(chloride) emission_current Mass concentration of total organics, ambient aerosol in air.(total_organics) Mass concentration of sulfate, ambient aerosol in air.(sulfate) inlet_open Mass concentration of ammonium, ambient aerosol in air(ammonium) Mass concentration of nitrate, ambient aerosol in air.(nitrate) sgpaosacsmC1.b1: org_mx_err Mass concentration of nitrate, ambient aerosol in air.(nitrate) Mass concentration of ammonium, ambient aerosol in air(ammonium) Mass concentration of chloride, ambient aerosol in air(chloride) org_mx Mass concentration of total organics, ambient aerosol in air.(total_organics) amus Mass concentration of sulfate, ambient aerosol in air.(sulfate)

Subject:	SGP/ACSM/C1 - Low inlet pressure in sample position
DataStreams:	sgpaosacsmC1.b1, sgpaosacsmC1.a1
Description:	The data are suspect because the new filter switching valve was out of adjustment causing low inlet pressure in the sample position. The problem was corrected by the onsite operator.
Measurements:	sgpaosacsmC1.a1: flow_rate vaporizer inlet_closed Mass concentration of chloride, ambient aerosol in air(chloride) emission_current Mass concentration of total organics, ambient aerosol in air.(total_organics) Mass concentration of sulfate, ambient aerosol in air.(sulfate) inlet_open Mass concentration of ammonium, ambient aerosol in air(ammonium) Mass concentration of nitrate, ambient aerosol in air.(nitrate) sgpaosacsmC1.b1: org_mx_err Mass concentration of nitrate, ambient aerosol in air.(nitrate) Mass concentration of ammonium, ambient aerosol in air(ammonium) Mass concentration of chloride, ambient aerosol in air(chloride) org_mx Mass concentration of total organics, ambient aerosol in air.(total_organics) amus Mass concentration of sulfate, ambient aerosol in air.(sulfate)
