Subject:
SGP/SIRS/E4 - Tracker failure
DataStreams:sgpsirsE4.b1, sgpsirs20sE4.a0
Description:
On 4/2, the station experienced a power drop after which the tracker was not operational 
until it was reset on 5/1.

The short_direct_normal (NIP instrument) and down_short_diffuse_hemispheric (8-48 
instrument) data were bad during this time.  The down_long_hemispheric (PIR) and 
down_short_hemispheric were unaffected by this failure.  Upwelling instruments were also unaffected.  
Three component DQ checks were not valid during this time.
Suggestions: 
Measurements:sgpsirs20sE4.a0:
  • Instantaneous direct normal shortwave irradiance, pyrheliometer thermopile
    voltage(inst_direct_normal)
  • Instantaneous uncorrected downwelling shortwave diffuse, shaded pyranometer
    thermopile voltage(inst_diffuse)
