PYE/GNDRAD/M1 - Reprocessed: IRT configuration and calibration

The configuration of the IRT was inadvertently set to default and the program of the data 
loggers were changed to that used at TWP.C3.  This caused the calibration of the data to 
be wrong. It was corrected by reconfiguring the IRT and changing the conversion factors 
in the data logger program.

These data have been reprocessed to apply correct calibrations and the reprocessed data 
were archived 20070212.

NIM/GNDRAD/M1 - Reprocessed: Longwave calibration error

Modified pyrgeometer calibration procedures were implemented beginning in December 2003. 
These modified procedures introduced a calibration bias in the longwave data.  The 
previous procedures were re-implemented at all sites between December 2005 and February 2006 to 
restore proper calibrations.									     
The data collected while the incorrect procedures were in place have been reprocessed to 
remove the calibration bias.  The reprocessed 60 second averaged data are based on 3 
instantaneous 20 second data records rather than on 60 1 second instantaneous data records.  
Still, these data are considered far superior to the originally processed data. The 
reprocessed data were archived in February 2007.

FKB/GNDRAD/M1 - Reprocessed: Incorrect calibrations

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.
