Subject: | PGH/AOS/M1 - Trailer temp too low, CCN affected |
DataStreams: | pghaosccn100M1.a1 |
Description: | The trailer temperature wasn't regulating very well. Night time temperatures fell to 10 C. The CCN doesn't operate well at low temperatures. As a consequence the instrument temperatures were below the acceptable range for the model calculation of %ss. The instrument still reported a %ss values, but this value is likely off by as much as 0.1%, especially at night when the trailer temperatures were low. |
