Subject:	TWP/SMET/C1 - Reprocess: Skewed wind direction 1 data
DataStreams:	twpsmet60sC1.a1, twpsmet60sC1.b1, twpsmet60sC1.00
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 - Surface pressure spike
DataStreams:	twpsmet60sC1.b1
Description:	A spike occured in the surface pressure. The reported pressure rose as high as 1300 hPa but returned to normal levels after 15 minutes.
