SGP/SIRS/E13 - UIR Instrument problem

Due to a bad connection the up_long_hemisp datastream (upwelling Epply PIR instrument) has 
intermittent missing data during the time range specified.

Missing data are not recoverable.  However, the sgpqcrad1longE13.c1 datastream adequately 
identifies missing values and removes them.  Recommendation to the user is to use this 
VAP datastream for valid values of up_long_hemisp irradiance from this station.

Use sgpqcrad1longE13.c1

• 10 meter Upwelling Longwave Hemispheric Irradiance, Pyrgeometer(up_long_hemisp)
• Upwelling Longwave Hemispheric Irradiance, Pyrgeometer, Minima(up_long_hemisp_min)

  Standard Deviation(up_long_hemisp_std)
