Subject: | SGP/MFRSR/E15 - Data not quality assured |
DataStreams: | sgpmfrsrE15.a0, sgpmfrsrE15.b1 |
Description: | Data from October 1, 1999 through March 2001 from MFRSR.E15 should be used with caution. During this time period only minimal quality control and maintenance were provided to the SGP extended facility MFRSRs because these data were considered to be of questionable value under the best of circumstances. That decision was reversed in 2001 when Joe Michalsky identified a means to make the MFRSR data scientifically useable. In the interim, the MFRSRs developed problems with shading, leveling, calibration and all-out hardware failures and the stock of spare MFRSRs was depleted and not replenished. Most of the shading and leveling problems have now been corrected in the field as well as possible, but almost all of the extended facilty MFRSRs still need to be recalibrated or replaced. |

Description: | Intermittent negative spikes in some channels and the head temp. A start date of 20050401 has been identified, but the problem may precede that date. 20050401 is the first date with obvious negative spiking. The instrument was on its way to failure, which it did just moments after this DQR ends. Interested users should examine the data closely, and remove affected points. Look for spikes in some channels, but not in others at the same time. |

Description: | Massive shading issue on 12/16 through 12/18. It was obviously found and resolved on 12/18. On 12/22 it looks like the shadowband stops functioning altogether. (It is likely it slipped on the motor shaft.) It continues like this until 12/28 @ 1630 when an attempt was made fix the problem. This was somewhat successful, but there is still a shading problem in the afternoon between 1730 and 2300 until 01/09/2008. Some data from 12/28/2007 - 01/09/2008 will be OK. Don't use data between the hours 1730 and 2300. Avoid data from other dates described in this DQR. |

Description: | Between 20071216 and 20080225 there are four stretches where the instrument is not shading properly. Those periods have been accurately designated in this DQR. Data outside these ranges are OK. Avoid using this instrument during times covered by this DQR. The hemispheric data may be OK, but with other good choices (C1 MFRSR and NIMFR), it is suggested to just avoid E13. |
