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:
  • Relative humidity at 60 m(rh_60m)
  • Vapor pressure at 25 m(vap_pres_25m)

SGP/TWR/C1 - 25m SW Incorrect
DataStreams:sgp1twr25mC1.b1, 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.
Measurements:sgp1twr25mC1.b1:
  • Vapor Pressure (kiloPascals)(vap_pres)
  • Beam 0 Temperature(temp)
  • Relative humidity inside the instrument enclosure(rh)
sgp30twr25mC1.b1:

DataStreams:sgp1twr10xC1.a1, sgp1twr10xC1.b1, sgp30twr10xC1.a1, sgp30twr10xC1.b1
Description:
The RH and therefore vapor pressure measurements on the 25 meter level, southeast side of 
the 60 m tower (data from CR10X) were incorrect because the relative humidity portion of 
the T/RH probe malfunctioned.  It is unknown at what day and time the failure occurred 
(it should be obvious from the data), although it was in the middle of the Fall combined 
IOP; I was not receiving the data at the time. The T/RH probe was replaced on 26 September.

SGP/TWR/C1 - SE side power low
DataStreams:sgp1twr10xC1.b1, sgp30twr10xC1.b1
Description:
A power outage caused a GFCI breaker to trip.  This removed power from the instruments on 
the tower.  Temperature, relative humidity, and the calculated vapor pressure at both 25 
m and 60 m levels are suspect because the sensors were not properly aspirated.
Measurements:sgp1twr10xC1.b1:
  • Relative humidity at 60 m(rh_60m)
  • Vapor pressure at 25 m(vap_pres_25m)

SGP/TWR/C1 - SE side 60m temp incorrect
DataStreams:sgp1twr10xC1.b1, sgp30twr10xC1.b1
Description:
60m temperature data for the southeast side of the tower was incorrect 
during the period because of a poor connection at the carriage data
connector.  The poor connection caused resistance to be too large as
seen by the PRTD sensor in the T/RH probe, resulting in temperatures that
were 2 to 6 degrees too large.  The problem ended when the carriage was 
lowered, then raised, reestablishing a good connection.
Measurements:sgp1twr10xC1.b1:
  • Temperature at 60 m(temp_60m)
sgp30twr10xC1.b1:
  • Temperature at 60 m(temp_60m)
