Subject: | GRW/MWR/M1 - Loose mirror |
DataStreams: | grwmwrlosM1.b1, grwmwrtipM1.a1 |
Description: | The data from the MWR were suspicious and became progressively worse. The problem was traced back to the fact that the screw that keeps the mirror in place had become loose and the mirror was freely rotating. The mirror was tightened on 6/9/2009, however the measurements were noisy until 6/16, when the instrument was rebooted and all the connections checked. Measurements between 5/1 and 6/9 should not be used. Data between 6/9 and 6/16 are usable, although they are very noisy. |

Subject: | GRW/TSI/M1 - Mirror reflection |
DataStreams: | grwtsiskycoverM1.b1 |
Description: | A deformity in the mirror produced an anomolous refraction within the mirror surface that appeared in the images as a white streak near the top of the mirror and shadowband. The mirror was replaced on 6/19. |

Subject: | GRW/VCEIL/M1 - Reprocess: Incorrect serial_number and sum_backscatter fields |
DataStreams: | grwvceil25kM1.b1 |
Description: | Attribute serial_number: In most cases, this field is not representative of the actual serial number of the instrument because the value did not change when an instrument changed locations or was replaced with a spare. Variable sum_backscatter: An out-of-range condition for the "sum of detected and normalized backscatter" was reported as 0 instead of missing (-9999). The valid range is 0 - 0.0999 /srad. |
