Subject:
ENA/NEPHELOMETER/C1 - Inlet flow changed
DataStreams:enaaosnephdry1mC1.b1, enaaosnephdryC1.a1, enaaosnephwet1mC1.b1, enaaosnephwetC1.a1,
enaaosnephwetC1.b1, enaaosnephdryC1.b1, enaaoshumidgrC1.01, enaaoshumidgrC1.00
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.
Suggestions: 
Use data with caution
