Description:
Beginning on December 24, Anemometer #1 (there are two anemometers on
the SMET stand) occasionally reported wind speed values that were low
relative to the other sensor.  It is clear from the data that the low
reading here is the anomalous one.

TWP/C2/SMET Temperature spike

which is calculated from the temperature and relative humidity.

TWP/C2/SMET - Pressure sensitivity to rain
DataStreams:twpsmet60sC2.a1, twpsmet60sC2.b1
Description:
The pressure behaves anomalously during rain events - even very mild
ones.  Normally, the pressure undergoes a smooth semi-diurnal
oscillation with little higher frequency variability.  However, during
and shortly after rain events, the pressure signal exhibits abrupt
changes - this sort of behavior has occasionally been observed at
Manus but not with the regularity seen here.  Examples of this
behaviour occur on (date in the form YYYYMMDD):

Description:
On April 1, 2001 at 00:00:00 new data header with consistent variable naming
conventions, etc were to be used for all sites, all data streams.  At the TWP
sites the time of the movement to the new convention did not occur precisely at 00:00:00.  
The following data files contain between 40 seconds and 20 minutes of data from 4/1/02 
in the old format.  The delayed format change did not affect data quality in any way.

TWP/C2  Installation
DataStreams:twpsmet60sC2.a1, twpsmet60sC2.b1, twpsmetC2.00
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.

Description:
Due to limitations of the Zeno dataloggers all voltage measurements
from the optical rain gauge (ORG) were converted to rainfall rates. 
This resulted in negative values for rain rates.  Any value below

alleviated this problem.

TWP/SMET/C2 - Reprocess: Tipping bucket rain gauge added
DataStreams:twpsmet60sC2.b1
Description:
A tipping bucket rain gauge was added to the TWP.C2 SMET suite of instruments on 20061129. 
Effective 20060926, two new variables (count and rain amount) were added to the end of 
the twpsmet60sC2.b1 datastream.  Between 9/26 and 11/29, the data for these two variables 
are filled with zeros.  Users should not use the data during this period as the zeros are 
not representative of the rain fall at the site.  When reprocessing of this datastream 
occurs these variables will be added for the 19981021-20060926 and data from 
19981021-20061129 will be filled with -9999 (missing).
Measurements:twpsmet60sC2.b1:
  • base time(base_time)
