Subject:
SGP/QCRAD/E16 - Tracker alignment issue
DataStreams:sgpqcrad1longE16.s2, sgpqcrad1longE16.c1, sgpqcrad1longE16.s1, sgpqcrad1longE16.c2
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.
Suggestions: 
null
Measurements:sgpqcrad1longE16.s2:
  • Shortwave direct normal irradiance, pyrheliometer(short_direct_normal)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer(down_short_diffuse_hemisp)
  • Quality check results on field: Best Estimate Global Downwelling Shortwave
