Subject:	NSA/MMCR/C1 - TWTA is inoperative
DataStreams:	nsammcrcalC1.a1
Description:	The TWTA failed and the MMCR is no longer transmitting or it may transmit irregularly.

Subject:	NSA/MMCR/C1 - Sudden Drop in Reflectivity
DataStreams:	nsammcrcalC1.a1
Description:	At 0800 on 11/21/03, the reflectivity dropped "unnaturally" (see the plot ). I checked the health messages and couldn't see any cause of this drop, i.e.tx power, t/r switches, power supplies, etc. I rebooted the system at 2230.

Subject:	NSA/MMCR/C1 - Reprocessing Notice (RID 153)
DataStreams:	nsammcrcalC1.a1
Description:	See below for details of reprocessing that was completed on 20150209. Original DQR category: 4 (Red, Incorrect). ----------------------------------------------------------- The OS/2 computer was replace on 10/24/2003 with a computer that was previously at SGP. The altitude in the cloud.par was not changed. The heights started at 423 meters instead of 112 meters. Only the heights in the nsammcrcalC1.a1 data stream were affected by this problem.
Measurements:	nsammcrcalC1.a1: Heights

Subject:	NSA/MMCR/C1 - Upgrade in process
DataStreams:	nsammcrcalC1.a1
Description:	The MMCR was undergoing a major upgrade during this period. At 0000 UTC on 20040415 the upgrade was complete. Old format NSA.C1 MMCR datastreams are not available after 20040413.1800. All MMCR data after 4/15 are available as nsammcrmomC1.b1 data.
