Subject:	SGP/MET/E13 - PWD data incorrect/missing
DataStreams:	sgpmetE13.b1
Description:	Data collection problems during the time period specified resulted in incorrect or missing PWD data.

Subject:	SGP/MWRHF/C1 - Reprocessed: Rapid drift in 90 GHz noise diode
DataStreams:	sgpmwrhfC1.b1
Description:	The noise diode of the 90 GHz channel was showing rapid drifts that affected the accuracy of the calibration. Although the algorithm is designed to follow slow drifts in the noise diode, in this case (because the variation was fast) the computed brightness temperature was probably about 4-5 K colder than it should be. Ingest was modified and data were reprocessed and archived in September 2011
Measurements:	sgpmwrhfC1.b1: Sky brightness temperature (90 GHz)(tbsky90)

Subject:	SGP/MPL/C1 - Water intrusion
DataStreams:	sgpmplpolfsC1.b1
Description:	Instrument temperatures were incorrect. On 02/01 and 02/03 they essentially flat lined at 0 C, while on 02/02 the temps were lower than normal (although given the external temp they may be accurate), with several data spikes throughout the day. Background signal values were excessively low throughout the entire period. Co- and cross-pol plotted values appear to have had a 3-5 km artificial elevation, resulting in plotted cloud bases appearing much higher than they actually were. System was not operating correctly due to water intrusion.

Description:	Apparent lightning strike in the instrument cluster area resulted in a failed NIP. Data are missing or incorrect. The SIRS was due for calibration change outs so the US, DS, DD and NIP were replaced. The updated program was loaded at approximately 06/14/2011 1739 GMT.

Description:	The neph backscatter shutter started to fail which resulted in large background values in the dry nephelometer. The data is poor quality even though it may look ok. Instead use the data in the wet nephelometer. Note that during some of this time period the RH value inside of this neph ramped up and down so use data at the low RH values.
