Subject:	SGP/QCRAD/E19 - Met data bad or missing
DataStreams:	sgpqcrad1longE19.c1, sgpqcrad1longE19.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 DQR D031110.8

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.
