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.
