Subject:	AWR/CCN/CPC/M1 - Concentration difference
DataStreams:	awraoscpcfM1.a1, awraoscpcfM1.b1
Description:	Various tests performed to understand why the CCN counts sometimes exceed those of a co-located CPC. Instrument functioning normally, but occasionally sampling cabin air during this period or running with internal flow lines opened for flow measurements.
Measurements:	awraoscpcfM1.a1: ambient_pressure condensation_temp liquid_level dilution_valve_position dilution_flow_setpoint fraction_full orifice_pressure nozzle_pressure dilution_flow_reading cabinet_temp AOS number concentration of CN (concentration)(concentration) laser_current optics_temp saturation_temp awraoscpcfM1.b1: fraction_full saturation_temp dilution_slope AOS number concentration of CN (concentration)(concentration) dilution_flow_setpoint optics_temp cabinet_temp nozzle_pressure orifice_pressure dilution_intercept dilution_valve_position dilution_flow_reading laser_current aerosol_flow_calibrated ambient_pressure dilution_correction_factor condensation_temp liquid_level
