TWP/C2/Sonde Missing Data
DataStreams:twpsondewnpnC2.a0, twpsondewnpnC2.a1, twpsondeC2.00, twpsondewnpnC2.00
Description:
There were no sondes launced during this period because there was
no helium on site and the hydrogen generator was not working.  The
hydrogen generator was repaired and launches resumed.

TWP/SONDE/C2 - Missing Winds
DataStreams:twpsondewnpnC2.a1, twpsondewnpnC2.a0
Description:
About half of the soundings in November-December exhibited drop-outs
in the winds.  These dropouts were typically over a depth of 1-2 km.
Sometimes the dropout occurred at the surface, sometimes at the top of
the sounding and sometimes in the middle.  These gaps occurred on:

TWP/C2  Installation
DataStreams:twpsondewnpnC2.a0, twpsondewnpnC2.a1, twpsondewnpnC2.00
Description:
The Nauru ARCS was installed during the period September-November
1998.  Data were being collected by the end of October, but for the
first several weeks of November, the site was undergoing considerable
change, so data from that period should be used with caution.  The
official site dedication occured on November 20.  Most on-site
activity ended following the dedication so we will consider November
20 to be the beginning of the Nauru operations.  The last members of
the installation team left Nauru on November 24.

the temperature-related data are incorrect.

  • Dry Bulb Temperature(tdry)
  • Dewpoint Temperature(dp)
  • Humidity, relative(rh)

TWP/SONDE/C2 - Bad RH Data (AIRS Validation Sonde)
DataStreams:twpsondewnpnC2.a1, twpsondewnpnC2.b1
Description:
The RH sensor heating circuit failed on this sonde.  This results in
oscillation of reported RH between reasonable values and values near zero.
This was an AIRS validation sounding.

  • Dewpoint Temperature(dp)
  • Humidity, relative(rh)

TWP/SONDE/C2  - Failure of RH sensor
DataStreams:twpsondewnpnC2.b1, twpsondewnpnC2.a1
Description:
It appears that the RH sensor heating circuit failed during this sounding.  The RH 
oscillates rapidly between low (~0 %RH) and not so low (ambient %RH) and the oscillation seems 
to stop when the temperature is below ~35 degC.  According to Vaisala these are symptoms 
of failure in the ASIC (application specific integrated circuit) that controls the heating.
Measurements:twpsondewnpnC2.a1:
  • Dewpoint Temperature(dp)
  • Humidity, relative(rh)
twpsondewnpnC2.b1:
  • Humidity, relative(rh)
  • Dewpoint Temperature(dp)
