TWP/C1 - Incorrect elevation reported in Manus Data
DataStreams:twpmplC1.a1, twpvceil25kC1.a1, twpvceil25kC1.b1
Description:
Bill Clements reports 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:twpmplC1.a1:
  • Dummy altitude for Zeb(alt)

twpvceil25kC1.a1:
  • Dummy altitude for Zeb(alt)

twpvceil25kC1.b1:
  • Dummy altitude for Zeb(alt)
