HFE/AOS/M1 - Data processing problem
DataStreams:hfeaosM1.a1, hfenoaaaosM1.b1, hfenoaaaosavgM1.b1
Description:
The AOS data was reprocessed for the AMF, SGP and NSA sites. There was an error in the 
processing of the corrections for the PSAP absorption signal such that a low pass filter was 
implemented for the scattering data used in these corrections.The difference between the 
corrected and previous data is < 0.05 Mm-1 (below the instrument detection limit) and 
should not have a significant effect on the previous data. Data will be reprocessed at a 
later time when more significant changes to the data processing are implemented.

Subject:
HFE/AOS/M1 - CPC and CCN data questionable
DataStreams:hfeaosccnM1.a1, hfenoaaaosM1.b1
Description:
The CPC slowly clogged and the signal declined until the instrument was cleaned at which 
point the signal would increase. The data is still a good relative measure of the daily 
changes in the CN concentration, but the absolute value may be too low.

The mentor was unable to monitor the flow rate and operation in the CCN during operation. 
The relative changes in CCN with %ss are likely fine, but the absolute values may be too 
low or too high. Dust was prevalent at the site and likely contributed to the CCN signal 
such that large dust particles appeared as droplets.
Measurements:hfenoaaaosM1.b1:
  • AOS number concentration of CCN(N_CCN)
  • Condensation Nuclei Concentration Number(N_CPC_1)
hfeaosccnM1.a1:
  • CCN_Q_sheath
  • AOS number concentration of CCN(N_CCN)
  • CCN_Q_sample
  • AOS CCN number concentration by bin(N_CCN_dN)
