SGP/CCN/S01 -  Concentration measurement differences

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.

Supersaturation values need to be recalculated.

• AOS CCN droplet count by bin size, first column(N_CCN_dN_1)
• AOS number concentration of CCN at supersaturation step 1(N_CCN_1)
• AOS CCN sample supersaturation set point value reported by instrument, first
  column(CCN_supersaturation_set_point_1)
• AOS number concentration of CCN at supersaturation step 2(N_CCN_2)
• AOS CCN sample supersaturation set point value reported by instrument, second
  column(CCN_supersaturation_set_point_2)
