Subject:
SGP/SIRS/E13 - UIR Instrument problem
DataStreams:sgpsirs20sE13.a0, sgpsirsE13.b1
Description:
Due to a bad connection the up_long_hemisp datastream (upwelling Epply PIR instrument) has 
intermittent missing data during the time range specified.

Missing data are not recoverable.  However, the sgpqcrad1longE13.c1 datastream adequately 
identifies missing values and removes them.  Recommendation to the user is to use this 
VAP datastream for valid values of up_long_hemisp irradiance from this station.
Measurements:sgpsirs20sE13.a0:
  • inst_up_long_case_resist
  • inst_up_long_hemisp_tp
  • inst_up_long_dome_resist
sgpsirsE13.b1:
  • up_long_hemisp_std
  • Upwelling Longwave Hemispheric Irradiance, Unventilated Pyrgeometer, Minima(up_long_hemisp_min)
  • Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)
  • inst_up_long_case_temp
  • inst_up_long_dome_temp
  • Upwelling Longwave Hemispheric Net Infrared(up_long_netir)
  • Upwelling Longwave Hemispheric Irradiance, Unventilated Pyrgeometer, Maxima(up_long_hemisp_max)
