Subject:	TWP/SMET/C1 - Reprocess: Skewed wind direction 1 data
DataStreams:	twpsmet60sC1.00, twpsmet60sC1.a1, twpsmet60sC1.b1
Description:	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.

Subject:	TWP/SMET/C1 - Wind Direction alignment method
DataStreams:	twpsmet60sC1.00, twpsmet60sC1.a1, twpsmet60sC1.b1
Description:	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).

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.

Subject:	TWP/SMET/C2 - Negative rainfall rates
DataStreams:	twpsmet60sC2.b1
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 0.10 mm/hr should be considered to be 0 mm/hr. New dataloggers alleviated this problem.

Subject:	TWP/SMET/C1 - Reprocess: Tipping bucket rain gauge added
DataStreams:	twpsmet60sC1.b1
Description:	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).
