TWP/SKYRAD/C3 - NIP instrument failure
DataStreams:twpskyrad20sC3.a0, twpskyrad60sC3.b1, twpskyradC3.00
Description:
The NIP (Short Direct Normal) was replaced after it displayed symptoms of failure 
associated with either unknown precipitation related issues or a possible lightning strike.

NIP data are not recoverable.  Direct normal data can be reconstructed from global 
hemispheric and global diffuse data using the following relationship:
   global hemispheric = direct*cos(sza) + diffuse hemispheric
Measurements:twpskyrad60sC3.b1:
  • Shortwave Direct Normal Irradiance, Pyrgeometer, Minima(short_direct_normal_min)
  • Shortwave Direct Normal Irradiance, Pyrgeometer(short_direct_normal)
  • Shortwave Direct Normal Irradiance, Pyrgeometer, Maxima(short_direct_normal_max)
  • Shortwave Direct Normal Irradiance, Pyrgeometer, Standard Deviation(short_direct_normal_std)
twpskyrad20sC3.a0:
  • Instantaneous Direct Normal Shortwave Irradiance, Pyheliometer Thermopile
    Voltage(inst_direct_normal)
twpskyradC3.00:
  • null(Raw data stream - documentation not supported)
