SGP/QCRAD/C1 - SW direct normal data drop out
DataStreams:sgpqcrad1longC1.c1, sgpqcrad1longC1.c2, sgpqcrad1longC1.s1, sgpqcrad1longC1.s2
Description:
NIP cable had failed during this time period.  Short_direct_normal data are not 
recoverable during this time period. However, it can be reconstructed using the following formula 
for each one minute data:
   short_direct_normal = (down_short_hemisp-down_short_diffuse_hemisp)/cos(zenith angle)

Documented in instrument DQR D090623.1

SGP/QCRAD/C1 - Failed upwelling SW cable
DataStreams:sgpqcrad1longC1.c1, sgpqcrad1longC1.c2, sgpqcrad1longC1.s1, sgpqcrad1longC1.s2
Description:
The upwelling shortwave hemispheric (up_short_hemisp) data were missing or incorrect due 
to a bad cable.  Cable was replaced on 6/30 and the problem was resolved.

Documented in instrument DQR D100701.1

SGP/QCRAD/C1 - NIP failure
DataStreams:sgpqcrad1longC1.c1, sgpqcrad1longC1.c2, sgpqcrad1longC1.s1, sgpqcrad1longC1.s2
Description:
The short_direct_normal (NIP instrument) cable failed during this time period.	Data are 
not recoverable.

Users can derive an estimate of direct normal values using the following formula:
short_direct_normal = (down_short_hemisp - down_short_diffuse_hemisp)/cos(zenith angle)

  • Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal)
