TWP/SMET/C3 - ORG data noisy due to degraded ground
DataStreams:twpsmet60sC3.b1
Description:
SMET Rain Data began to be noisy during December 2005 and the problem slowly became worse 
over time so that in February 2006 the ORG was reporting with a constant background value 
of around 0.10 mm/hr rain rate.  ORG voltage showed a near constant value above the 85mV 
threshold.  The ground for the ORG had become degraded and was lost due to corrosion.
Measurements:twpsmet60sC3.b1:
  • Precipitation mean(precip_mean)
  • Precipitation maximum(precip_max)
  • Precipitation standard deviation(precip_sd)
  • precipitation minimum(precip_min)

TWP/SMET/C3 - Reprocess: Windspeed2 calibration error
DataStreams:twpsmet60sC3.b1
Description:
The lower anemometer was replaced afer being removed in anticipation of cyclone Monica. 
The calibration coefficient was not changed during this period so the wind speeds are a 
little low (0.2%).
Measurements:twpsmet60sC3.b1:
  • Wind #2 speed vector average(wind2_spd_vec_avg)
  • Wind #2 speed arithmetic average(wind2_spd_arith_avg)
  • Wind #2 speed maximum gust(wind2_spd_max_gust)
  • Wind #2 speed minimum(wind2_spd_min)
  • Wind #2 speed maximum(wind2_spd_max)
  • Wind #2 speed standard deviation(wind2_spd_sd)

TWP/GNDRAD/C3 - IRT failed
DataStreams:twpgndrad60sC3.b1
Description:
The IRT began to fail on 4/7/2006 and failed completely (apparently due to the internal 
power supply) on 4/27. It was replaced on 5/18.

  • Surface Infra-Red Temperature, Standard Deviation(sfc_ir_temp_std)
  • Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
  • Effective Surface (Skin) Temperature(sfc_ir_temp)
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)
