DataStreams:sgpmwrlosC1.b1, sgpmwrlosE14.b1, sgpmwrtipC1.a1, sgpmwrtipE14.a1
Description:
Between 01/12 and 01/15 brightness temperatures show high values (Tb > 100 K) indicative 
of rain, however the wet_window flag is 0 (indicative of no rain). During that time there 
where freezing conditions with ice pellets that were not detected by the sensor. The high 
brightness temperatures may be due to melting ice on the window.

SGP/AOS/C1 - CPC failure
DataStreams:sgpaosC1.a1
Description:
The Condensation Particle Counter stopped recording counts. Upon inspection the tech found 
that water had condensed in the reservoir. The CPC was shipped back to the mentor for 
repair and a replacement CPC from NOAA was sent to the site.

The replacement Condensation Particle Counter stopped measuring particle counts and was 
removed and returned to NOAA. The thermoelectric cooler in the device had stopped working. 
The ARM CPC that had previously been sent back to NOAA for repair was fixed and returned 
to SGP.

SGP/AOS/C1/ - Pump failure
DataStreams:sgpaosccnC1.a1
Description:
The ratio of CCN to CN started to noticeably decline around 20070901. After a site visit 
on 20071023, the mentor found a problem with the instrument flows and diaphragm pump.  The 
instrument was return to Boulder, CO for repair. The diaphragm pump was repaired and the 
flows re-calibrated. The instrument was returned to service 20071113. 

The CCN data show qualitative changes in the number of droplets formed with changes in 
supersaturation. Because the pump was not working properly and the flows were likely 
incorrect, the numbers are not quantitative.
Measurements:sgpaosccnC1.a1:

SGP/AOS/C1 - Pump failure and subsequent failure of humidified nephelometer
DataStreams:sgpaosC1.a1
Description:
The pump for the aerosol sampling system failed over a weekend. The humidifier continued 
to operate and soaked the inside of both the reference and wet nephelometers. The 
nephelometers were returned for repair. A replacement neph was installed on 2008-August 5 @1858 
UTC. The nephs were repaired and returned to SGP in December 2008. The humidification 
system was rebuilt and installed on 2009 January 6 at 1912 UTC.
