SGP/AOS/C1 - Data processing problem
DataStreams:sgpaosC1.a1, sgpnoaaaosC1.b1, sgpnoaaaosavgC1.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.
