SGP/TWR/C1 - Temperature Sensor Not Connected to Datalogger
DataStreams:sgp1twr10xC1.b1, sgp30twr10xC1.b1
Description:
One of the southeast side 25 m Temperature sensor leads was pulled out from the CR10X 
datalogger terminal strip.

  • Pressure, vapor, 25-m height, 30-min intervals(vap_pres_25m)

SGP/TWR/C1 - Southeast Side RH Too Large
DataStreams:sgp1twr10xC1.b1, sgp30twr10xC1.b1
Description:
The T/RH probes installed on the 25 m and 60 m levels of the southeast side of the tower 
on 8/15/03 gave RH readings that were too large for RH above 65%. The difference between 
the west and southeast side RH was within the combined accuracies of the sensors up to 
about 80% RH.  Above 80% RH the southeast side RH was much larger, with the difference 
increasing to 10% larger (or more) at 100% RH.  The vapor pressure from the southeast side 
(calculated with RH) was also too large.

The probes were replaced on 2/10/04 and the two sides of the tower now agree
fairly well, with RH not exceeding 100% during saturation.
Measurements:sgp1twr10xC1.b1:
  • Pressure, vapor, 60-m height, 30-min intervals(vap_pres_60m)

SGP/TWR/C1 - Southeast Side (10X) Temperature and RH Spikes
DataStreams:sgp1twr10xC1.b1, sgp30twr10xC1.b1
Description:
Southeast side 25 m and 60 m (10X datastreams) carriage connectors may not have been well 
connected; temperatures and relative humidities spiked sometimes.  This problem occurred 
after the carriages were lowered on 12/04.
