PYE/SKYRAD/M1 - Reprocessed: Installation problems

The installation of the SKYRAD instrument was not without problems.  During all or part of 
the time period specified the calibrations were incorrect or incomplete, the downwelling 
diffuse and direct normal leads were switched, and the shadowband was severely out of 
alignment.

These data have been reprocessed to apply corrections as follows:

1) NIP & PSP-diffuse leads swapped 20050214-20050412.1645
     - swapped the NIP and PSP columns in the raw data files
     - backed out the original, incorrect calibrations 
     - applied correct calibrations
2) PSP-diffuse calibration error 050214-050215
     - backed out the original, incorrect calibration
     - applied correct calibrations
3) PSP-DS cal error 050214-050215
     - backed out the original, incorrect calibration
     - applied correct calibration
4) NIP cal error 050214-050215 and 050218-050401
     - backed out the original, incorrect calibrations
     - applied correct calibration

The reprocessed data were archived in February, 2007.

Users are encouraged to still use these data with caution only after a thorough quality 
review to be certain the data meet their requirements.
