Subject:	ENA/NEPHELOMETER/C1 - Humidigraph flow issues

09/08/2016	0024	11/24/2016	1730	Suspect

Subject:	ENA/NEPHELOMETER/C1 - Inlet flow changed
DataStreams:	enaaosnephwet1mC1.b1
Description:	Due to a failure of another instrument on the same sample line, the sample flow for the nephelometers/humidigraph was different than specified. This potentially affected the humidigraph RH and the impactor cut point. Full effect on data quality is unknown, but is likely limited to the impactor cut point being slightly different than expected.
