Subject:	SGP/SIRS/E9 - Intermittent downwelling diffuse data
DataStreams:	sgpsirs20sE9.a0, sgpsirsE9.b1
Description:	The downwelling diffuse (8-48) data were dropping out intermittently beginning on the night of 8/5. Ops repaired damaged cable on 11/12 but problem was last observed on 10/27.
Suggestions:	Disregard the downwelling diffuse data during the indicated time ranges.
Measurements:	sgpsirsE9.b1: Downwelling Shortwave Diffuse Hemispheric Irradiance, Pyranometer, Standard Deviation(down_short_diffuse_hemisp_std) Downwelling Shortwave Diffuse Hemispheric Irradiance, Pyrgeometer, Minima(down_short_diffuse_hemisp_min) Downwelling shortwave diffuse hemispheric irradiance, pyranometer, maxima(down_short_diffuse_hemisp_max) Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer(down_short_diffuse_hemisp) more sgpsirs20sE9.a0: Instantaneous uncorrected downwelling shortwave diffuse, shaded pyranometer thermopile voltage(inst_diffuse) more
