SGP/AOS/C1 - Failed RH sensor
DataStreams:sgpaosC1.a0
Description:
The RH sensor inside the humidified nephelometer began to slowly decline in value in the 
upper RH range beginning in early 2004 and becoming more noticable poor on 20041117. The 
sensor currently reaches a high RH value of about 60% when the actual RH is closer to 80%.

The sensor was replaced in the Spring of 2005, but the problem remained.  Effective 
1/1/2004, this sensor is not used to calculate scientific data and is therefore essentially 
abandoned in the field.  An end-date of 20050501 is being used as a placeholder.

SGP/AOS/C1 - Optical Particle Counter (PCASP-X) down
DataStreams:sgpaosC1.a0, sgpaosauxC1.a0
Description:
The AOS Optical Particle Spectrometer (PCASP-X sizing probe) was down during these 
periods.  This lowers the laser reference voltage and results in inaccurate sizing.
