TWP/C2/Sonde Missing Data
DataStreams:twpsondeC2.00, twpsondewnpnC2.00, twpsondewnpnC2.a0, twpsondewnpnC2.a1
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.a0, twpsondewnpnC2.a1
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/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.

TWP/C2  Installation
DataStreams:twpsondewnpnC2.00, twpsondewnpnC2.a0, twpsondewnpnC2.a1
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.
