Subject:
TWP/SMET/C1 - Reprocess: Skewed wind direction 1 data
DataStreams:
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.
Measurements:twpsmet60sC1.b1:
  • Wind #1 direction standard deviation(wind1_dir_sd)
  • Wind #1 direction vector average(wind1_dir_vec_avg)
  • Wind #1 speed vector average(wind1_spd_vec_avg)
twpsmet60sC1.00:
  • null(Raw data stream - documentation not supported)
twpsmet60sC1.a1:
  • Wind #1 direction vector average(wind1_dir_vec_avg)
  • Wind #1 speed vector average(wind1_spd_vec_avg)
  • Wind #1 direction standard deviation(wind1_dir_sd)

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.
Measurements:twpsmet60sC1.b1: 
  • Barometric Pressure(atmos_pressure)
