Subject:
TWP/SKYRAD/C1 - UVB Data questionable/incorrect due to uncontrolled sensor temperature
DataStreams:twpskyrad20sC1.a1, twpskyrad60sC1.b1
Description:
The UVB was not temperature controlled to 25C as required
to ensure accurate data.  UVB data should ONLY be used after 
checking both the bit_data and twpskyrad20sC1.a1 uvb_temp
or inst_down_uvb_temp.  UVB data where the UVB temperature
was outside the range of 24-26C should not be used.
Measurements:twpskyrad60sC1.b1:
  • Downwelling Ultra-Violet Irradiance, UV Biometer(down_uvb)
  • Downwelling Ultra-Violet Irradiance, UV Biometer, Minima(down_uvb_min)
  • Downwelling Ultra-Violet Irradiance, UV Biometer, Standard Deviation(down_uvb_std)
  • Downwelling Ultra-Violet Irradiance, UV Biometer, Maxima(down_uvb_max)
twpskyrad20sC1.a1:
  • Instantaneous Uncorrected Downwelling Ultraviolet Irradiance, UV Biometer(inst_down_uvb_irradiance)
  • Instantaneous Downwelling Ultraviolet Biometer Temperature(inst_down_uvb_temp)
