TWP/QCRAD/C3 - NIP failure
DataStreams:twpqcrad1longC3.c1, twpqcrad1longC3.c2, twpqcrad1longC3.s1, twpqcrad1longC3.s2
Description:
NIP data is bad during this time until a new instrument was installed. Direct normal 
shortwave irradiance incorrect during this time. 

Problem described in instrument DQR D061120.1
Measurements:twpqcrad1longC3.s2:
  • Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal)
twpqcrad1longC3.s1:
  • Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal)
twpqcrad1longC3.c2:
  • Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal)
twpqcrad1longC3.c1:
  • Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal)

TWP/QCRAD/C3 - Tracker inoperative
DataStreams:twpqcrad1longC3.c1, twpqcrad1longC3.c2, twpqcrad1longC3.s1, twpqcrad1longC3.s2
Description:
Tracker inoperative because hit by lightning. Diffuse and direct normal shortwave 
irradiance incorrect during this time. LW downwelling data can have higher uncertainties under 
direct sun.

Problem described in instrument DQR D090129.1
Measurements:twpqcrad1longC3.s2:
  • Radiation, shortwave, downwelling diffuse hemispheric irradiance, 1-min avg(down_short_diffuse_hemisp)

TWP/QCRAD/C3 - GNDRAD shutdown for tropical cyclone
DataStreams:twpqcrad1longC3.c1, twpqcrad1longC3.c2, twpqcrad1longC3.s1, twpqcrad1longC3.s2
Description:
On Jan 3rd approximately 1000GMT the effects of a tropical cyclone started affecting the 
installed radiometer measurements at ARM/TWP/C3(Darwin) - both SKYRAD and GNDRAD.  On Jan 
4th, 0740 GMT the GNDRAD was shutdown to avoid damage due to the close passing of this 
storm. GNDRAD was restarted Jan 7th 0515GMT.
Measurements:twpqcrad1longC3.s2:
  • Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)
  • Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp)
twpqcrad1longC3.s1:
  • Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp)
  • Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)
twpqcrad1longC3.c2:
  • Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp)
  • Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)
twpqcrad1longC3.c1:
  • Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp)
  • Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)
