NIM/AOS/M1 - Flow controller failure
DataStreams:nimaosccnM1.a1, nimaosM1.a1
Description:
Following a power outage at the site both a PID controller for the main sample flow as 
well as a circuit board on the reference nephelometer were inoperable. The PID controller 
was replaced on 5/18 and the neph circuit board was replaced on 6/22. On a site visit in 
August the mentor found the PID had not been programmed correctly and was reading erroneous 
flows. The actual flow was at 50% of the recorded flow. Because the sample flow is 
diluted by 50% this makes most if not all of the sample flow from 5/18 to 8/11 from the diluter.

NIM/AOS/M1 - Data processing problem
DataStreams:nimaosM1.a1
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.
