TWP/SMET/C1 - Reprocess: Skewed wind direction 1 data

Wind direction 1 data is incorrect. 
Manus SMET wind direction for Wind-1 (upper unit) was apparently skewed
from its original position as a result of checking direction calibration. 

As near as we can tell the position of the sensor was rotated clockwise
Somewhere in the range of 45-90 degrees, most likely in steps 22.5 degrees.

Data comparison performed on 3-2-00, using a small amount of data from 
this instrument.

TWP/SMET/C1 - Wind Direction alignment method

During RESET10 we discovered a problem with wind direction from WIND1 (upper
anemometer).  During RESET8, WIND1 was corrected by rotating the alignment
ring instead of the anemometer.  This resulted in a better agreement between
the 2 anemometers, but is not the correct way to align an anemometer. The
alignment ring was readjusted for true north and the anemometer reset in
the proper slot (the original problem).

TWP/SMET/C1 - Incorrect calibration for ARCS1 Wind speed

On 23 OCT 99, during Reset 8, an incorrect slope of was entered for the 
upper, windspeed1, wind speed sensor resulting in a 1% overestimate of
the wind speed.  The correct calibration was entered on 1 APR 2000 during
RESET 10.

TWP/SMET/C1 - Periodic spikes in temperature and water vapor pressure

Beginning on 980212 (day #43) spikes began to occur in the surface
temperature and water vapor pressure.  These spikes occur approximately
once per hour (the spacing is very regular but occasionally an hour
is skipped).  In the one-minute averaged data, the temperature spike
lasts for only one minute and dips approximately 4-5 C below the actual
temperature.  The one-minute standard deviation is more dramatic, rising
from about 0.1 to about 35.  The one minute temperature minimum is the
most easily identifiable, each hour when the spike occurs, the minimum
is -245.84.  The vapor pressure mean jumps from about 30 to over 50 and
the standard deviation jumps from less than 1 to more than 200.  This
problem was fixed by the RESET team on 980501.

TWP/SMET/C1 - Elevated relative humidity

The relative humidity has been exceeding 100% with unusual regularity.
The most dramatic case occured on December 31 when the RH exceeded 100%
for 18 hours and exceeded 103.5% for 6 hours with a maximum value of
103.8%.  A PIF was submitted to propose changing this sensor. This change
occurred on August 12, 1999.

TWP - Switch to new Data Header Formats not timely

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/C1 - Incorrect elevation reported in Manus Data

(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/SMET/C1 - Reprocess: Miscalibrated windspeed2 data

A replacement anemometer (WSP2) was installed but the new anemometer calibration 
coefficients were not put into the logger. The multiplication factor was 0.09708 when it should 
have been 0.09763 (very small difference)the offset was 0.36 when it should have been 0.3 
(a difference 0.06 m/s).

TWP/SMET/C1 - Reprocess: Wind Speed #2 incorrect

Wind Speed #2 sensor was reporting values 10 times above the actual value.  During an 
update to the logger configuration file the calibration multiplier was incorrectly entered.  
The multiplier inserted was .97630 when it should have been .09763.  This caused the 
readings from this sensor to be incorrect.

TWP/SMET/C1 - Poor Performing Sensor

On 4/23/2004 condensation was found inside the target area of the ORG lens. A spare was 
sent and installed but did not solve the problem of high background voltage values causing 
rainrate values to be recorded during no rainfall.  Values range anywhere from 0.06 to 
0.12 mm/hr.  

A new Optical Rain Gage was installed on 01/19/2005 @ 13:30 GMT alleviating the high 
background voltage values that lead to consistent rainfall rates of around 0.11 to 0.15 mm/hr 
on a consistent basis.  

The formula used to calculate rainfall rates from the new Optical Rain Gage is:  RR 
(mm/hr) = 25(V^1.87) - 0.15.

Older model formula = 20(V^2) - 0.05

The two formulas result in comparable data.

TWP/SMET/C1 - Incorrect rainrate equation used

There are two different Optical Raingages in use at the TWP sites.  The incorrect equation 
was used at this site.  The incorrect equation is (25*(V^1.87)) - 0.15.
The correct equation is (20*(V^2)) - 0.05.  The correct equation was installed.

TWP/SMET/C1 - Negative rainfall rates

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 0.10 mm/hr should be 
considered to be 0 mm/hr.  New dataloggers 
alleviated this problem.  New loggers were installed 03/09/2004 @ 2243 GMT.

sensor showed that the upper sensor flat-lines for long periods of time.  The upper

TWP/SMET/C1 - Reprocess: Barometric Data Changed from hPa to kPa

Barometric pressure data was converted from hPa to kPa in order to standardize the 
measurement units among ARM sites and to conform to accepted standard units determined by the 
scientific community.

TWP/SMET/C1 - Reprocess: Tipping bucket rain gauge added

A tipping bucket rain gauge was added to the TWP.C1 SMET suite of instruments on 20061017. 
 Effective 20060926, two new variables (count and rain amount) were added to the end of 
the twpsmet60sC1.b1 datastream.  Between 9/26 and 10/17, 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 19961009-20060926 and data from 
19961009-20061017 will be filled with -9999 (missing).
