NSA/MWR/C1 - Instrument problem, Heater problem
DataStreams:nsamwrlosC1.b1
Description:
The heater of the MWR was ON all the time even when the moisture sensor was dry. Jim 
Liljegren suspected a problem with the relay that activates the heater. The suggested action 
was to send the faulty assembly to SGP for repair and get a spare unit from SGP.
The spare unit was sent on 9/15 and was installed on 10/18.

NSA/MWR/C1 - New software version (4.15) installed
DataStreams:nsamwrlosC1.b1
Description:
A problem began with the installation of MWR.EXE version 4.12 in September 2002. The 
software had been upgraded from a "DOS" to a "Windows"-compiled program to address an earlier 
problem.  The software upgrade corrected the earlier problem but introduced a new one 
that caused line-of-sight observing cycles to be skipped, a 15% reduction in the number of 
tip curves, and saturation of CPU usage.  Software versions 4.13 and 4.14 also produced 
these problems.

The new MWR software version (4.15) was installed on 9/15/2005. As a consequence of this 
upgrade, the tip curve frequency increased. The tip cycle time decreased from ~60s to ~50s.

NSA/MWR/C1 - Reprocessed and Corrected:wrong calibration
DataStreams:nsamwrlosC1.b1
Description:
DATA REPROCESSED and CORRECTED: 

The calibration had changed as a result of the repairs made by Radiometrics and the RF 
deck temperature had been set to 325K for testing. The temperature was decreased to 307K to 
prevent thermal instability in winter and the calibration was changed in the 
configuration file with the values supplied on the repair report. The calibration coefficients were 
derived automatically after the changes were put into affect. The data were reprocessed 
using the derived calibration coefficients.

ORIGINAL DQR CATEGORY: Red( Incorrect)

REPROCESSED and CORRECTED DATA ARCHIVED:2016-03-29

REPROCESS IDENTIFICATION NUMBER: RID 209
 
---------------------------------------------------
--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------
When MWR#20 was returned to service on 9/1/2005, the calibration had changed as a result 
of the repairs made by Radiometrics and the RF deck temperature had been set to 325K for 
testing. On 9/2, the temperature was decreased to 307K to prevent thermal instability in 
winter and the calibration was changed in the configuration file with the values supplied 
on the repair report.  

The data need to be reprocessed with the calibration coefficients that were automatically 
derived after these changes were put into affect. They are: tnd_nom23=185.621, 
tnd_nom31=158.801, tc23=-0.022, tc31=-0.039.

NSA/MWR/C1 -  Incorrect time stamp
DataStreams:nsamwrlosC1.b1
Description:
On Sept 27 the motherboard of the MWR computer was replaced. Following the replacement, 
the date on the computer was not set to the correct time of day, therefore the date and 
time in the files were wrong. The time on the computer was reset on Sept. 30. Time stamps 
between Sept. 27 and Sept. 30 were later corrected based on gathered information, however 
they may have as much as 5 minutes of uncertainty.

NSA/MMCR/C1 - Sensitivity Loss, Calibration Wrong
DataStreams: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.
