Subject:
NSA/MMCR/C1 - Pulse controller failed due to water damage

Description:
Instrument had water damage that fried the pulse controller
card.  Images appear normal, but no clouds were detected
during this period because no radar pulse was being emitted.

Note from Karen Johnson: the ARSCL and MMCRMODE data fields
may or may not be suspect, depending on whether ARSCL correctly
identified the MMCR data as bad.
