Subject:	NSA/MMCR/C1 - Sensitivity Loss, Calibration Wrong
DataStreams:	nsammcrmomC1.00, nsammcrmomC1.b1, nsammcrspecmomC1.a0
Description:	Jay Mace compared data from CLOUDSAT to the MMCR and found significant discrepancies. It appears that the MMCR has a sensitivity problem and is underreporting reflectivity by ~20 dBZ. A comparison with the MPL shows that this might be a gradual degradation, i.e. there are no apparent shifts identifying when this might have occured.

Subject:	NSA/MMCR/C1 - Antenna Feed Corrosion
DataStreams:	nsammcrmomC1.b1, nsammcrspecmomC1.a0
Description:	During a trip to Barrow, I inspected the feed under the antenna and noticed an extreme amount of corrosion that has resulted in the flexible waveguide connected to the feed to be pushed off at an angle with corrosion in between. I attempted to remove and clean but the corrosion has effectively welded the two pieces together. This didn't happen overnight and the start date is a guess. The last inspection of the antenna probably took place in April 2004 when we did the C40 DSP upgrade. I don't know how much the reflectivity is affected by this corrosion. It may be possible to get an idea once we replace the antenna by making some intercomparison measurements. The feed was temporarily repaired on 10/16/2007 until the new antenna was installed. The measured loss before and after the repair was 5.1 dB. This means that the MMCR was under-reporting reflectivity by 10.2 dB just before it was repaired. That said, there is no way of ascertaining what the rate of corrosion was and how the loss changed during the period of this DQR. One can assume that the 5.1 dB loss was the worst that it was.
