Description:
The MMCR parameter file was taken from Nauru on 8/30/02.  It took several days due to 
communications problems to get the following variables changed to their correct values:

Site, Latitude, Longitude, Altitude

Otherwise, the data are correct.

TWP/MMCR/C1 - Reprocess: Inaccurate reflectivity data
DataStreams:twpmmcrcalC1.a1
Description:
The MMCR was down at the time of the normal auto-calibration on 20031027.  When the radar 
came back up, the calibration was wrong, which caused unrealistically high reflectivity 
values to be reported.  The calibration was corrected during the normal auto-calibration 
on 20031107.

It may be possible to recover data for this period by applying the calibration determined 
on 20031107 to the entire period affected.
