Subject: | SGP/TWR/C1 - West-side 25m data incorrect due to low battery |
DataStreams: | sgp30twr25mC1.b1 |
Description: | A low battery voltage caused T, RH, and VP to be incorrect. Data may be missing from some of the second period because battery voltage dropped to zero at one point. |

Subject: | SGP/TWR/C1 - 25m SW Incorrect |
DataStreams: | sgp30twr25mC1.b1 |
Description: | Wires were touching the fan inside the aspirator of the 25m SW 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. |

Subject: | SGP/TWR/C1 - Temp data suspect |
DataStreams: | sgp30twr25mC1.b1 |
Description: | The 1twr25m_temp data stream remained constant (data looks stepped) at varying intervals and appears erroneous when compared with the other twr measurements. The problem was only severe for the time period indicated. This behavior has been seen before and since, but usually not this severe. It has a small effect on the calculated vapor pressure. |
