Description:
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
DataStreams:nsamwrpC1.b1
Description:
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.

Description:
The months of November and December have been very rainy and wet at the AMF site. During 
rain events the radiometer does not work properly because of water accumulating on the 
window. In addition condensation and fog will affect the data causing very high brightness 
temperatures. Although the instrument is equipped with rain detection system to flag bad

FKB/MWRP/M1 - Possible slight drift of V-band calibration
DataStreams:fkbmwrpM1.b1
Description:
During the month of November and December the bias between model computations and 
measurements for the 51.25 and 52.28 GHz channels has slightly increased to about 3 K. This might 
be due to a slight drift in the calibration of these channels.

The calibration error associated with these data is increased, to 2-3 K, for these two 
months. See this plot for a comparison of measurements (solid lines) and model (red 
dots) for the 51.25 (black), 52.28 (blue) and 53.85-GHz (green) channels.

FKB/MWRP/M1 - Periodic decrease in the 30-GHz brightness temperature
DataStreams:fkbmwrpM1.b1
Description:
Starting around 12/19 until the end of December, the 30-GHz brightness temperature started 
to show a periodic oscillation between 9 and 11 AM GMT. The cause of this is probably 
thermal instability of the radiometer since it does correspond with some larger 
oscillations of the mixer temperature. During this time external temperatures displayed large 
variations going from -10 C at night to about +5 C during the day. The corresponding liquid 
water path retrievals are affected showing periodic negative values.

Liquid water path retrievals between 12/19 and 12/31 are the most affected variable since 
they are largely affected by the 30-GHz channel. A time series plot of the data will 
clearly show the periodic fluctuation of the LWP variable.

NSA/MWRP/C1 - V-band Noise diode unstable
DataStreams:nsamwrpC1.b1
Description:
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 - Radiometer in mixed scanning-zenith mode
DataStreams:nsamwrpC1.b1
Description:
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.

NSA/MWRP/C1 - Reprocessed: LN2 calibration
DataStreams:nsamwrpC1.b1
Description:
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.

Data reprocessed 20080610.

NSA/MWRP/C1 - Reprocessed: Incorrect calibration
DataStreams:nsamwrpC1.b1
Description:
The calibration of the MWRP drifted starting on September 21. The drift caused a negative 
LWP. On 10/21 I modified the calibration of the 30 GHz channel in an attempt to correct 
for the negative bias in LWP. The change in the calibration however caused an excessive 
increase in the PWV retrievals. The original calibration values were reinstated on 10/29. I 
then recomputed the temperature coefficients as well as the noise diode injection 
temperature from tip curves and uploaded the new values on Nov 15 2010. 

Reprocess the data from 9/21 to 11/15 with the newly computed coefficients.

Reprocessing completed 20110111.
