Subject: | 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. |
