Subject:	MAO/SMPS/S1 - clogged impactor at the SMPS aerosol sample inlet
DataStreams:	maoaossmpsS1.a1
Description:	The clogging of the impactor leads to a decrease in the aerosol sample flow rate of the SMPS, which is nominally 1 lpm. This decrease in the SMPS sample flow rate results in an underestimation of the ambient size distribution and integrated number concentration.
Measurements:	maoaossmpsS1.a1: aerosol_flow CPC_inlet_flow Total concentration(total_concentration) Number size distribution (dN/dlogDp)(number_size_distribution) CPC_sample_flow
