Subject:
SGP/QCRAD/E1 - Missing surface met data
DataStreams:sgpqcrad1longE1.s2, sgpqcrad1longE1.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.

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

Most periods with missing data described in instrument DQRs: D991109.1, D080617.4, 
D080617.5
Suggestions: 
Use caution with LW up and down pyrgeometer irradiance, dome temperature, case 

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