PGH/AOS/M1 - Bad nephelometer calibration
DataStreams:pghaosclap3wM1.a1, pghaosnephdryM1.a1, pghaosnephwetM1.a1, pghaospsap3wM1.a1
Description:
A bad calibration was entered for both nephelometers. Poor quality CO2 gas was suspected. 
A good calibration was taken in March 2012 and applied to the data for the entire 
campaign in the .b1 level data product. Errors are expected to be small.

PGH/AOS/M1 - Humidifier heater stopped working
DataStreams:pghaosnephwetM1.a1
Description:
The PID controller for the humidograph heater stopped working. The RH inside the wet neph 
stopped ramping up and down each hour and so there aren't any frh data for the fRH VAP.

PGH/CPC/M1 - Global metadata error
DataStreams:pghaoscpcM1.a1
Description:
The global metadata in the pghaoscpcM1.a1 file incorrectly specifies the CPC model number 
as "3372". The correct model number is "3010".

This is a metadata error only. The data are not affected. A low priority reprocessing task 
has been submitted.
