TWP/MFRSR/C1 - Reprocess: Corrupt Data
DataStreams:twpmfrsrC1.a0, twpmfrsrC1.a1, twpmfrsrC1.b1
Description:
An examination of the raw data indicated that the raw data was apparently good, so the 
data corruption entered the data stream during the calibration of the raw files.  It was 
found that the dark-count offset in the calibration files was far, far too large.  This 
offset was set to zero (the usual procedure except in special cases) and the data now look 
very good.  ASCII files were sent to Andy Vogelmann along with supplementary data (ios, 
etc.) and I mentioned that these data had only been inspected visually and therefore could 
still be erroneous -- althought I don't think Andy will discover any errors because from a 
visual standpoint these data look fine.  It took several days to identify the proble and 
reprocess these data but at least Andy has good data now (or so we hope).  -Jim Barnard

TWP/C1 - Incorrect elevation reported in Manus Data
DataStreams:twpmfrsrC1.a0, twpmfrsrC1.a1, twpmfrsrC1.b1
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.
