NSA/MMCR/C1 - NSA/C1/MMCR- Incorrect Calibrations
DataStreams:nsammcrcalC1.a1, nsaarscl1clothC1.c1, nsammcrmode03v0081clothC1.c1,

Description:
From 3-July 2001 to 26-July 2001, the NSA MMCR calibration for the
two coded pulse modes is incorrect.  The values of reflectivity computed
by the radars autocalibration software are wrong because they use the
wrong radar constant.  The correct radar constants are: 8-bit coded
mode RC=16.344 and for the 32-bit coded RC=7.313. 

The only impact of the incorrect radar constants should be reflectivity
value
