Subject:	NSA/SONDE/C1 - Bad surface RH and temperature values
DataStreams:	nsasondewnpnC1.b1
Description:	This is a subtle problem that might escape notice. For the identified sonde launches, the ground station lost its signal between the time it was removed from the ground check set and the time it was launched. As a result, the software, which automatically determines the launch time and surface conditions at time of launch mistakenly used values of temperature and RH representative of the ground check set and the GW rather than of the ambient conditions before launch. The bad values influenced only the first few samples and the remainder of the sounding values are correct. A procedural problem was identified and corrected.

Subject:	NSA/SONDE/C1 - RH values offset due to error in ground check
DataStreams:	nsasondewnpnC1.b1
Description:	Background: After installation of the latest software update , we began performing formal ground checks on RS92 radiosondes. By comparing the radiosonde readings with reference values in a controlled environment, the ground check is intended to ensure that the radiosonde sensors are in calibration before launch. The radisonde values during the ground check process are recorded automatically; the reference values are entered by the operator. If the radiosonde readings vary from the reference values, the system 'corrects' the radiosonde values. In the case of RH, the correction is applied as an offset (true RH = indicated RH + correction). Problem: Some operators misunderstood the ground-check procedure and entered the radiosonde values of RH rather than the reference value (assumed 0%RH), thus, some soundings done during this period have RH values that are different from what they would be if the ground check procedure had been done correctly. Consequence: Because the RH corrections generally are small (averaging about 0.5% RH) and the precision of the reported RH data during this time period is 1% RH, some values will not be affected at all; others will be off by about 1% RH (still within the stated accuracy of the sensor). Furthermore, because entering the radiosonde value as the reference value results in a near zero 'correction,' one may view these soundings as being done without the ground check correction. Also note that the dew point value will be suspect as well. I am attaching below a listing of the soundings that were affected during the indicated time period. Users can see the magnitude of the problem and choose whether or not to apply an offset in RH. Note that application of the offset to the processed RH data (in the netCDF file) will not have the same effect of applying the correction to the absolutely raw data (before processing), but the differences should be insignificant. Also note that the corrections for each sounding are included in the netCDF header information. These attributes are named 'humidity_correction' and 'humidity_correction_2'. The values of RH indicated by the radiosonde while it is in the ground check set are in attributes 'humidity_gc_sonde' and 'humidity_gc_sonde_2.' There is an RH reading for each of the two RH sensors used in the RS92 radiosonde. Here is the list - RH1 and RH2 are the radiosonde readings in the ground check set. Ref is the reference value entered by the operator. The correcte reference value should be 0%. To obtain an approximation to the RH value that would have been recorded if the ground check had been done properly, subtract the Ref value from the indicated RH.

DataStreams:	nsasondewnpnC1.b1
Description:	It appears that one of the two RH sensors on this radiosonde was affected by ice after emerging from a low cold cloud. As a result the reported RH values oscillate by about 10 percent until the alternate heating cycle stops. I suspect the lower value is more close to correct, but can't be absolutely sure.

Subject:	NSA/MWRP/C1 - Reprocessed: K-Band calibration drift
DataStreams:	nsamwrpC1.b1
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.

Subject:	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.

Subject:	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.

DataStreams:	nsamwrpC1.b1
Description:	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.

Subject:	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.

Subject:	NSA/MWRP/C1 - Reprocess: 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.

DataStreams:	nsametC1.b1, nsatwrC1.b1
Description:	The new t/rh probe installed during annual calibrations and checks began to exhibit readings that were biased high compared to the Chilled Mirror Hygrometer. In high RH conditions the sensor would consistently report RH values in excess of 105%. Comparisons to the other tower levels also suggested that the 2m level RH data is suspect.

Subject:	NSA/MWRP/C1 - Reprocess: 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.
