Subject: | SGP/MFRSR/E13 - Shadowband misalignment |
DataStreams: | sgpmfrsrlangleyE13.c1, sgpmfrsrE13.b1, sgpmfrsrE13.a0, sgpmfrsrlangplotE13.c1 |
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. |
Suggestions: | Use C1 MFRSR or C1 NIMFR rather than this instrument. |
