SGP/SIRS/E22 - Reprocess: Incorrect calibration coefficients
DataStreams:sgpsirsE22.00, sgpsirsE22.b1, sgpsirs20sE22.a0
Description:
NIP (short_direct_normal) 29541E6 had an incorrect calibration coefficient in the logger 
program. 128.97 should have been 126.67 [W/m2/mV].

SGP/SIRS/E9 - Downwelling SW cable problem
DataStreams:sgpsirsE9.00, sgpsirsE9.b1, sgpsirs20sE9.a0
Description:
The down_short_diffuse_hemispheric data were erratic beginning 0109 GMT March 27 2007.  
Found rodents had chewed DD cable.  Repaired April 3rd 1625GMT.

Data are not recoverable. However, it can be reconstructed using the following shortwave 
instrument relationship on a minute by minute basis:
Measurements:sgpsirs20sE9.a0:
  • Instantaneous Uncorrected Downwelling Shortwave Diffuse, Shaded Pyranometer
    Thermopile Voltage(inst_diffuse)
sgpsirsE9.b1:
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer,
    Minima(down_short_diffuse_hemisp_min)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer,
    Maxima(down_short_diffuse_hemisp_max)
