Subject:
FKB/GNDRAD/M1 - Reprocessed: Incorrect calibrations
DataStreams:fkbgndrad20sM1.a0, fkbgndrad60sM1.b1
Description:
An incorrect calibration coefficient was applied to the up_short_hemispheric instrument 
(PSP) for the specified time period.  Changes in the ARM PSP calibration procedure now 
generates two different calibration coefficients for the same instrument, Cf(non "IR 
corrected")and Cfc("IR corrected").  CFc should have been applied to this instrument but CF was 
erroneously used.

The affected PSP is S/N 34292F3 Cf=117.61 (incorrect applied), Cfc(correct)=116.07W/m2/mV

These data were reprocessed and archived in March 2008.
Measurements:fkbgndrad60sM1.b1:
  • Upwelling (10 meter) Shortwave Hemispheric Irradiance, Pyranometer, Minima(up_short_hemisp_min)
  • Upwelling (10 meter) Shortwave Hemispheric Irradiance, Pyranometer, Standard
    Deviation(up_short_hemisp_std)
  • Upwelling (10 meter) Shortwave Hemispheric Irradiance, Pyranometer, Maxima(up_short_hemisp_max)
  • Upwelling (10 meter) Shortwave Hemispheric Irradiance, Pyranometer(up_short_hemisp)
