Subject: | TWP/SKYRAD/C2 - UVB Data questionable/incorrect due to uncontrolled sensor temperature |
DataStreams: | twpskyrad60sC2.b1, twpskyrad20sC2.a1
|
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. |
Suggestions: | Use all UVB data from Nauru with caution, checking the
uvb_temp info in the twpskyrad20sC2.a1 data stream. |
Measurements: | twpskyrad60sC2.b1: - Downwelling Ultra-Violet Irradiance, UV Biometer, Maxima(down_uvb_max)
- Downwelling Ultra-Violet Irradiance, UV Biometer, Standard Deviation(down_uvb_std)
- Downwelling Ultra-Violet Irradiance, UV Biometer, Minima(down_uvb_min)
- Downwelling Ultra-Violet Irradiance, UV Biometer(down_uvb)
