TWP/SKYRAD/C2 - reprocess: PIR identified as unshaded is really shaded
DataStreams:twpskyrad20sC2.a1
Description:
On 17Sep01 the Global PIR was moved from the unshaded position
on the Skyrad stand to the new 'shaded' spot on the new K&Z tracker.
It is still using the same Logger channel as it did as an unshaded 
PIR even though it is now shaded.

This problem has been documented in P011109.2.  This DQR should
be linked to that PIF and an end date added when the problem is
resolved.

  • inst_down_long_unshaded_dome_resist
  • Irradiance, longwave, downwelling, hemispheric, thermopile (Shaded Pyrgeometer2)(inst_down_long_hemisp_unshaded_tp)

TWP/SKYRAD/C2 - UVB Data questionable/incorrect due to uncontrolled sensor temperature
DataStreams:twpskyrad60sC2.b1, twpskyrad20sC2.a1, twpskyrad60sC2.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.
