Subject:
SGP/QCRAD/E16 - Met data not available
DataStreams:sgpqcrad1longE16.c2, sgpqcrad1longE16.c1
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.

The Rayleigh limit diffuse radiation test is based on surface pressure.

There were no instrument DQRs on this problem at the time this report was submitted.
Suggestions: 
Use caution with LW up and down pyrgeometer irradiance, dome temperature, case 

temperature, SW up data and diffuse irradiance data because all quality control checks could 
not be run.
