Subject:	MAO/AOS/M1 - Weak solder connection in dilution flow meter comport cable
DataStreams:	maoaosccn100M1.a1, maoaosclap3wM1.a1, maoaoscpcM1.a1
Description:	The dilution flow meter reading was erratic. Plots of the data suggest that the flow varied by about 5%. Problem was corrected when wire was re-soldered.
Suggestions:	null
Measurements:	maoaoscpcM1.a1: Aerosol concentration averaged over times to match N_CCN(concentration) more maoaosclap3wM1.a1: Aerosol light absorption coefficient, nominal blue wavelength at dry or reference RH(Ba_B_CLAP3W) Aerosol light absorption coefficient, nominal red wavelength at dry or reference RH(Ba_R_CLAP3W) Aerosol light absorption coefficient, nominal green wavelength at dry or reference RH(Ba_G_CLAP3W) more maoaosccn100M1.a1: Cloud condensation nuclei number density(N_CCN) AOS CCN number concentration by bin(N_CCN_dN) more
