SGP/AOS/C1 - Ozone Instrument removed for repair
DataStreams:sgpaosC1.a0, sgpaosauxC1.a0
Description:
The ozone instrument was removed for calibration on 2003 11/21.  It was shipped to Boulder 
and was cleaned and calibrated.  It was sent back to SGP on 2003 12/02, but was damaged 
in transit by FedEx.  The instrument was reinstalled on 2003 12/03 but was found to be 
defective.  Large spikes were observed in the data.  Afetr a few days the instrument was 
removed and shipped to a vendor for repair.  The ozone monitor was returned to service 
after repair at 2004 01/27 (2208 GMT).

SGP/AOS/C1 - Wet nephelometer problems
DataStreams:sgpaosC1.a0, sgpaosauxC1.a0
Description:
The humidifier tube was coated with mold and had to be replaced. This affects the wet 
nepheleometer measurements and the calculations of the aerosol hygroscopic growth.

The humidifer was cleaned and replaced. A filter was added to the water circulation to 
minimize mold.

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.
