Subject:
TWP/SMET/C2 - Lower windspeed sensor questionable
DataStreams:twpsmet60sC2.b1
Description:
Lower wind speed sensor had degraded bearings.  This sensor was reporting as much as 0.4 
m/s lower values than the upper sensors when the winds were 2 m/s or below.  The sensor 
was replaced.
Measurements:twpsmet60sC2.b1:
  • Wind #2 speed maximum(wind2_spd_max)
  • Wind #2 speed vector average(wind2_spd_vec_avg)
  • Wind #2 speed maximum gust(wind2_spd_max_gust)
  • Wind #2 speed standard deviation(wind2_spd_sd)
  • Wind #2 speed arithmetic average(wind2_spd_arith_avg)
  • Wind #2 speed minimum(wind2_spd_min)
