Subject: | SGP/MFRSR/E16 - Possible date/time corruption |
DataStreams: | sgpmfrsrE16.a0, sgpmfrsrE16.b1 |
Description: | Incorrect capacitors in the loggerboard during this time resulted in corruption of the raw data. Date and time information as well as logger and head ID were incorrectly reported for some records. Much of the data from this period can not be processed (missing) and the remaining data should be used with caution. Users of these data should be alert for unexplained discontinuities in the .a0 and .b1 level data sets. |

Subject: | SGP/MFRSR/E16 - Data not quality assured |
DataStreams: | sgpmfrsrE16.a0, sgpmfrsrE16.b1 |
Description: | Data from October 1, 1999 through March 2001 from MFRSR.E16 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: | A shading problem is first noticed on 1 April 2007. Initially it is very minor, but grows progressively worse until maintenance resolved the issue on 17 July 2007. During April and May it is minor enough that most users can likely use the data without issue. On 5 June the shading becomes suddenly much worse, and from this time on users would certainly want to screen the data between sunrise and 1630 UTC. |
