FKB/MET/M1 - Optical Rain Gauge Data Incorrect
DataStreams:fkbmetM1.b1
Description:
The Optical Raingauge (ORG) data was incorrect during the listed times.  Ice/frost was 
forming on the lenses causing the ORG to believe there was precipitation occurring.
Measurements:fkbmetM1.b1:
  • Precipitation rate standard deviation(precip_rate_sd)
  • Precipitation rate mean(precip_rate_mean)
  • Precipitation rate maximum(precip_rate_max)
  • Precipitation rate minimum(precip_rate_min)

Subject:
FKB/MET/M1 - ORG Data incorrect during calibration
DataStreams:fkbmetM1.b1
Description:
The ORG data was incorrect during calibration checks.  The check mimics a precipiation 
event so the precip amounts that were collected were not actually measured.
Measurements:fkbmetM1.b1:
  • Precipitation rate standard deviation(precip_rate_sd)
  • Precipitation rate mean(precip_rate_mean)
  • Precipitation rate maximum(precip_rate_max)
  • Precipitation rate minimum(precip_rate_min)

Subject:
FKB/MET/M1 - Optical Rain Gauge Data Incorrect
DataStreams:fkbmetM1.b1
Description:
Precipitation was being reported on days with no rain.  Problems with the grounding and 
the orientation of the receiver facing south (sunlight in the optics) caused erroneous 
readings.
Measurements:fkbmetM1.b1:
  • Precipitation rate standard deviation(precip_rate_sd)
  • Precipitation rate mean(precip_rate_mean)
  • ORG carrier mean(org_carrier_mean)
  • Precipitation rate maximum(precip_rate_max)
  • Precipitation rate minimum(precip_rate_min)

Subject:
FKB/SKYRAD/M1 - IRT bias
DataStreams:fkbskyrad60sM1.b1
Description:
The sky temperature measurement from the IRT exhibited a positive bias from the AERI 
measurement each day from about 20:00 to 07:00. This diurnal variation is highly correlated 
with the measurement of relative humidity so it may be due to the contribution of water 
vapor temperature.
Measurements:fkbskyrad60sM1.b1:
  • Sky/Cloud Infra-Red Temperature(sky_ir_temp)
