Bad upwelling IR signal, bad upwelling SW signal

Data has been collected at site E4 since
about April 1995.  We have just started to examine data from this
site taken from about 1 March 1996.  We do not know the quality of
the data before this date.  After this date, the signal from
the upwelling IR pyrgeometer is bad, as well as the signal from the
upwelling SW pyranometer.

Suggested Corrections of the Problem:

Inspect and fix the offending instruments (the repairpersons at the
SGP site have been notified about these instruments).
