Subject:
SGP/QCRAD/E16 - Tracker alignment issue
DataStreams:sgpqcrad1longE16.s2
Description:
Tracker appears to be out of alignment or inoperative during these times. The 
short_direct_normal (NIP) and down_short_diffuse_hemisp (8-48) data appear to be bad and not 
recoverable.

There were no instrument DQRs on this problem at the time this report was submitted.
Measurements:sgpqcrad1longE16.s2:
  • Irradiance, shortwave, downwelling, diffuse, hemispheric, pyranometer(down_short_diffuse_hemisp)
  • Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp)
  • Irradiance, shortwave, direct normal, pyrheliometer(short_direct_normal)

SGP/QCRAD/E16  - Tc/Td bad or noisy
DataStreams:sgpqcrad1longE16.s2
Description:
Case and dome temperatures for longwave fluxes are sporadically bad or noisy during these 
periods corresponding to additional noise in the longwave fluxes. Some checks can't be 
applied to the LW fluxes.

No instrument DQRs exist documenting this problem.
Measurements:sgpqcrad1longE16.s2:
  • Downwelling Longwave Hemispheric Irradiance, Pyrgeometer(down_long_hemisp)
  • LWdnTc
  • LWdnTd
  • Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)
  • LWupTc
  • LWupTd
