DataStreams: | sgpmfrsrE6.a0, sgpmfrsrE6.b1 |
Description: | Data from October 1, 1999 through March 2001 from MFRSR.E6 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: | This site had a new instrument and logging system installed May 07. The first data we retrieved were in June and the instrument heater was not functioning. Maintenance on 8/5/2007 resolved the issue. The head is designed to operate at 40 deg C, and we like to see it stay within a few degrees of 40 deg C during normal operation. While the irradiance data look OK, there could be subtle issues resulting from the head temperature not being stable. |

The 29th has the same shadowing issue and missing diffuse channels, up until 1900 when they all appear. This situation repeats on 20090130. It is again just after a period of missing data.
