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.

SGP/AOS/C1 - Nephelometer shutter error
DataStreams:sgpnoaaaosC1.b1, sgpaip1ogrenC1.c1, sgpaosnephdryC1.a1, sgpnoaaaosavgC1.b1,
sgpaipavg1ogrenC1.c1, sgpnoaaaosfitrhC1.b1
Description:
The neph backscatter shutter started to fail which resulted in large background values in 
the dry nephelometer. The data is poor quality even though it may look ok.

Instead use the data in the wet nephelometer. Note that during some of this time period 
the RH value inside of this neph ramped up and down so use data at the low RH values.
