Subject:	SGP/CCN/S01 - Concentration measurement differences
DataStreams:	sgpaosccn200S01.a1
Description:	Total particle number concentrations different approximately by 20-30% between the two columns at the same supersaturation setpoints. Possible cause - differences in column temperature gradients. Data is suspect. Updated calibration coefficients are needed to derive correct supersaturation values from the recorded temperatures.
Measurements:	sgpaosccn200S01.a1: AOS CCN droplet count by bin size, second column(N_CCN_dN_2) AOS number concentration of CCN, second column(N_CCN_2) Cloud droplet concentration number from summation of condensation nuclei counter size bins(N_CCN_1) AOS CCN droplet count by bin size, first column(N_CCN_dN_1) CCN_supersaturation_set_point_2 CCN_supersaturation_set_point_1
