NSA/MWRP/C1 - Reprocessed: K-Band calibration drift

At the beginning of November, the K-band channel calibration started to drift. The MWRP 
brightness temperatures were about 1.5 K higher than the MWR-measured brightness 
temperatures. By the half of the month the differences were more than 2 K to become about 4 K by 
the end of November. On Nov 27 new calibration coefficients were derived and uploaded.

Data for 20061101-20061127 have been reprocessed with the revised calibrations and are 
available from the ARM Archive effective January 2007.

NSA/MWRP/C1 - Incorrect surface measurements

The MWRP surface temperature and pressure readings were in disagreement with those from 
other instruments. The possible cause of the disagreement was ice buildup around the 
sensors.  Readings returned to normal March 29.

The temperature readings were more affected. Since the readings are erratic, with large 
oscillations, it is not possible to correct them. Disregard the surface temperature and 
humidity readings during this time. The wrong readings will affect the first layer of the 
temperature and humidity profiles as well.

NSA/MWRP/C1 - Reprocessed: 6-channel retrieval replaced by 5-channel retrieval

Due to repeated failure of the V-band receiver and calibration problems, the 6-channel 
retrieval was retired and a new 5-channel retrieval which uses only the K-band channels was 
implemented.

All data previously processed with the 6-channel retrieval have been reprocessed.

Please note that the 7 channels (brightness temperatures) in the V-band range (51 to 60 
GHz) should not be used.  See D080331.1 and D080331.2.

During this time the radiometer was thermally unstable . The noise diode physical 
temperature had sudden drops of more than 5 degree in several ccasions between 2/1 and 2/11. On 
2/12 the radiometer temperature set point was lowered of about 10 degree as a test. On 
2/27 a new analog board was installed in the instrument. Data after 2/27 show a slight 
change in calibration.

NSA/MWRP/C1 - V-band Noise diode unstable

Sometimes between Jan and March 2007 the V-band noise diode started to be unstable. V-band 
channels during this period show large discrepancies with model computations. The 
problem was evident during the month of January. During February and March the problem was less 
visible, however measurement model comparisons show an increased bias. The instrument 
was calibrated with LN2 on March 15 and the calibration results showed a large drift in the 
calibration parameters.  The hardware failure will have consequences in the retrievals 
of temperature and relative humidity profiles. 

It is difficult to establish when the failure started. Disregard the V-band channels 
during this period. Vertical profiles of temperature and humidity are affected as well. Please 
note that this DQR only covers the 7 channels (brightness temperatures) in the V-band 
range (51 to 60 GHz). The 5 K-band channels (20-31 GHz) are not affected.

NSA/MWRP/C1 - V-band Noise diode failure

The LN2 calibration on 3/15 showed a large drift of the V-band calibration parameters. The 
radiometer was calibrated again in June and was sent out for repairs in July 2007.

Between 3/15 and 7/13 2007 the V-band data are incorrect and should be disregarded. The 
failure affects the retrieved vertical profiles of temperature and humidity as well.

Please note that the hardware failure affected the 7 V-band channels only (51-60 GHz). 
Channels in the frequency range between 20 and 30 GHz are not affected. Integrated liquid 
water (LWP) and water vapor (PWV) are not affected since they use K-band channels only.

A spare radiometer was provided by Radiometrics while they try to fix our MWRP. The spare 
radiometer is of the same family as the one we have in Barrow and it will stay at the 
site until our radiometer is repaired.
A LN2 calibration will be performed next week.

NSA/MWRP/C1 - Radiometer in mixed scanning-zenith mode

After installing the spare radiometer (D080409.2), the data started to be intermittent and 
the software froze several times. To test if the problem was due to the scanning 
procedure used with the other radiometer, the instrument was run with a zenith-only procedure at 
times and with the usual scanning procedure at restart. When restarted with the scanning 
procedure the software had problems, so it was decided to run the spare instrument only 
with the zenith-viewing mode until our instrument comes back.

The quality of the data should be unaffected. The only difference is that only data 
collected at 90 degree angle will be available until our instrument comes back.

A spare radiometer was installed a the site to substitute the malfunctioning radiometer 
(see DQRs D080409.2 and D080421.1). During this time the spare radiometer had problems 
starting and was stopping collection suddenly. Data during this time are very intermittent

NSA/MWRP/C1 - Reprocess: LN2 calibration

On 4/9 a spare radiometer was installed at the site. On 4/18 a LN2 calibration was 
conducted. Upon examination of the data it appeared that the LN2 calibration was generally 
successful, however the 30-GHz channel was not calibrated properly.
New calibration coefficients for all K-band channels were derived and data for the whole 
month should be reprocessed with these newly derived coefficients. I will provide the new 
configuration file.

An explanation of the effects of the poor calibration is given in the Instrument Mentor 
Monthly Summary report. The poor calibration affected the LWP in particular. Re-calibration 
will correct the problem.

NSA/MWRP/C1 - V-band noise diode failure

The V-band noise diode is showing signs of instability. Starting about August 5 the 
comparison of brightness temperatures with model showed an increased divergence resulting from 
a downward trend in the brightness temperatures of frequencies > 50 GHz.

Disregard brightness temperatures and retrieved products associated with the V-band 
channels. These include all profiles. Integrated water vapor and liquid water path are not 
affected.

After the radiometer was installed at the site following extensive refurbishing the 
retrieved LWP had a large negative bias (~-0.07 mm). The calibration coefficients were modified 
and that resolved the problem. Data for February, March and part of April were 
reprocessed with the revised calibrations and archived in July.
