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. |
