SGP/AOS/C1 - Suspected leak in CCN and or problem with instrument optics
DataStreams:sgpaosccnC1.a1
Description:
The CCN signal started a slow decline during this period. The instrument was removed and 
shipped back to the mentor for repair. A leak was found in the instrument which would've 
decreased the over all signal. Whether this leak affected the rate of CCN growth with %SS 
is uncertain.
Measurements:sgpaosccnC1.a1:
  • Cloud condensation nuclei number density(N_CCN)
  • CCN_Q_sheath
  • CCN_Q_sample
  • CCN_ss_set
  • CCN_ss_calc
  • AOS CCN number concentration by bin(N_CCN_dN)
  • AOS bin number of lowest channel of OPC include in summation of N_CCN(N_CCN_bin_number)
