TWP/GNDRAD/C1 - PIR: Extended data gap

The lines to the GNDRAD data logger were cut on December 2, 1996 at
approximately 1400 GMT.  No data was collected from GNDRAD until the
lines were reconnected on December 12 at approximately 0200 GMT.  The
PIR was not reconnected properly, however, and data flow from that
instrument did not resume until a RESET visit in February.  Data flow
for the PIR resumed on February 28, 1997.  The IRT and Net radiometer
appear to be operating as before, but without the downlooking PIR, we
cannot perform any internal tests.
