Subject:	SGP/TWR/C1 - 25 m SW Temperature Incorrect
DataStreams:	sgp1twr25mC1.b1, sgp30twr25mC1.b1
Description:	Wires were touching the fan inside the aspirator of the 25 m SW (B side) level. This occurred during maintenance to instruments on the SW side on 8/05/04; vibration of the carriage probably jostled the wires loose. The temperature and relative humidity sensors were not adequately ventilated and therefore produced incorrect measurements of temperature, relative humidity, and vapor pressure.
