Subject: | SGP/QCRAD/E9 - Missing surface met data |
DataStreams: | sgpqcrad1longE9.c1, sgpqcrad1longE9.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. There were no instrument DQRs on this problem at the time this report was submitted. |

DataStreams: | sgpqcrad1longE9.c1, sgpqcrad1longE9.c2, sgpqcrad1longE9.s1, sgpqcrad1longE9.s2 |
Description: | Direct normal irradiance measurements appear to be incorrect. The cause of the problem is not known. No instrument DQR is available describing the problem at this time. |

DataStreams: | sgpqcrad1longE9.c1, sgpqcrad1longE9.c2, sgpqcrad1longE9.s1, sgpqcrad1longE9.s2 |
Description: | Case and dome temperatures for Longwave fluxes are noisy during this period corresponding to additional noise in the longwave fluxes. No instrument DQRs exist documenting this problem. |
