Subject:
SGP/QCRAD/E15 - Temp and RH measurements incorrect
DataStreams:sgpqcrad1longE15.c2
Description:
Surface meteorological data were missing during these time periods. Met data is used in a 
variety of quality control checks described below.

Air temperature data is needed for tests on LW up and LW down pyrgeometer case and dome 
temperatures, and tests on the irradiances from upwelling LW/SW and downwelling LW.

Most periods with missing data described in instrument DQRs: D980521.1, D980616.1
Measurements:sgpqcrad1longE15.c2:
  • Temp_Air
  • LWdnTd
  • LWdnTc
  • Irradiance, shortwave, upwelling, hemispheric, 10 meter(up_short_hemisp)
  • LWupTc
  • Irradiance, shortwave, downwelling, diffuse, hemispheric, pyranometer(down_short_diffuse_hemisp)
  • Humidity, relative, at 21-m height, 30-min avg(rh)
  • Downwelling Longwave Hemispheric Irradiance, Pyrgeometer(down_long_hemisp)
  • LWupTd
  • Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)

SGP/QCRAD/E25 - Missing Best estimate and global values
DataStreams:sgpqcrad1longE25.c2, sgpqcrad1longE25.s2
Description:
Many best estimate and GSW values are missing during this time period. Some of this data 
could be filled with MFRSR measurements.
Measurements:sgpqcrad1longE25.c2:
  • Downwelling shortwave hemispheric irradiance, pyranometer(down_short_hemisp)
  • Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp)
sgpqcrad1longE25.s2:
  • Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp)

Subject:
SGP/QCRAD/E25 - NIP data questionable
DataStreams:sgpqcrad1longE25.c2, sgpqcrad1longE25.s2
Description:
Direct normal irradiance values are strange during this period. No instrument DQR 
currently exists documenting the problem and its cause is not known.
Measurements:sgpqcrad1longE25.c2:
  • Irradiance, shortwave, direct normal, pyrheliometer(short_direct_normal)
sgpqcrad1longE25.s2:
  • Irradiance, shortwave, direct normal, pyrheliometer(short_direct_normal)
