TWP/C1 - Incorrect elevation reported in Manus Data
DataStreams:twpsondewnpnC1.a1
Description:
(From Bill Clements) We have been using 6m MSL as the station
elevation of Momote (Manus).  This was based on information
posted near the station barometer in the Momote Weather Service
Office.  It turns out that the official WMO station elevation
for Momote is 4m MSL and the upper air elevation is 5m MSL.

All Manus instruments except the sonde station are at 4m MSL.
The sonde launching station is at 5m MSL.

Description:
On November 18 the generator was turned off due to a fault in the oil
pressure sensor. It had been having trouble for at least a day prior
to the manual shut-down. ADaM, the MPL, and the WSI were also shut
down to prevent an unscheduled power cycle. As a result, there is a block 
of missing data from November 20-27 for all of the instruments except 
those connected to the Zeno loggers (SKYRAD, GNDRAD, SMET).

TWP/C1 - Incorrect elevation reported in Manus Data
DataStreams:twpsondewnpnC1.a1
Description:
(From Bill Clements) We have been using 6m MSL as the station
elevation of Momote (Manus).  This was based on information
posted near the station barometer in the Momote Weather Service
Office.  It turns out that the official WMO station elevation
for Momote is 4m MSL and the upper air elevation is 5m MSL.

All Manus instruments except the sonde station are at 4m MSL.
The sonde launching station is at 5m MSL.
Measurements:twpsondewnpnC1.a1:

TWP/Sonde/C1 - Bad RH Values
DataStreams:twpsondewnpnC1.a1, twpsondewnpnC1.b1
Description:
The RH values from the surface to approximately 11.5 km oscillate between reasonable 
values and zero.  This is apparently caused by a failure in the RH sensor heating process.  
Although the oscillation stops when the heating stops (at temperatures below ~ -45degC) I 
think the values must be viewed as suspect.
Measurements:twpsondewnpnC1.b1:
  • Surface dew point temperature(dp)
  • Relative humidity scaled, by total column amount from MWR(rh)

TWP/SONDE/C1 - Questionable RH
DataStreams:twpsondewnpnC1.a1, twpsondewnpnC1.b1
Description:
It appears that the RH sensor heating circuit failed during this portion of the sounding 
(approximately between 5km and 10km).  The RH oscillates rapidly between low (~5 %RH) and 
not so low (~50 %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:twpsondewnpnC1.b1:
  • Surface dew point temperature(dp)
  • Relative humidity scaled, by total column amount from MWR(rh)
twpsondewnpnC1.a1:
  • Relative humidity scaled, by total column amount from MWR(rh)

Description:
The RH sensor heating circuit failed on this radiosonde.  The RH-related values obtained 
between 0 and 10000 meters oscillate between near-zero and reasonable ambient values.  
Above 10000 the RH values are likely correct.
