TWP/SKYRAD/C1 - IRT affected by rain or shutter
DataStreams:twpskyrad60sC1.b1
Description:
During this time period, the SKYRAD IRT was affected by rain
events.  Water collected on the IRT lens resulting in
elevated and invalid measurement of the sky brightness
temperature.  If the front optic was not dried after a heavy
rain, the data contamination could persist for several days.

The original solution to the problem was to have the local
observers clean the front lens after rains.  In April 1998,
a rain shutter was installed, but it did not become fully 
functional until Aug 9, 1998.

After the rain shutter was installed, the IRT data was
invalid during rain events while the shutter was closed
but ok again immediately after the shutter re-opened.

The configuration of the IRT was changed Oct 19, 2001.
The IRT was mounted such that the field of view is directed
downward at a 30 degree elevation angle and reflected
to the vertical by a front-surfaced, gold-plated mirror.
This configuration prevents rain from directly striking
the lens and collecting in the lens barrel.

Data from 10/96-3/99 were examined and times when the
data are invalid are identified below.  Data from 4/99-10/01
also contain periods of invalid data, but it is left to
the data users to identify those periods and filter the
data according to their needs.

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)

  • Instantaneous Uncorrected Downwelling Ultraviolet Irradiance, UV Biometer(inst_down_uvb_irradiance)
  • Instantaneous Downwelling Ultraviolet Biometer Temperature(inst_down_uvb_temp)

TWP/SKYRAD/C1 - PIR identified as shaded2 is really an unshaded instrument
DataStreams:twpskyrad20sC1.a1, twpskyrad60sC1.b1
Description:
On Oct 24, 2001, the Global PIR was moved from the unshaded
position on the SKYRAD stand to a shaded position on the new
K&Z tracker.  The data for all time are named "shaded2" 
indicating that this PIR was ALWAYS shaded.  From 19961010
to 20011024, this was not the case.
Measurements:twpskyrad20sC1.a1:
  • Instantaneous Downwelling Pyrgeometer Dome Thermistor Resistance, Shaded
    Pyrgeometer2(inst_down_long_shaded2_dome_resist)
  • Instantaneous Downwelling Pyrgeometer Thermopile, Shaded Pyrgeometer2(inst_down_long_hemisp_shaded2_tp)
  • Instantaneous Downwelling Pyrgeometer Case Thermistor Resistance, Shaded
    Pyrgeometer2(inst_down_long_shaded2_case_resist)

  • Downwelling Longwave Hemispheric Irradiance, Shaded Pyrgeometer2, Standard
    Deviation(down_long_hemisp_shaded2_std)
