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/MWR/M1 - Incorrect ambient temperature |
DataStreams: | grwmwrlosM1.b1, grwmwrtipM1.a1 |
Description: | The ambient temperature readings are incorrect. Problem appeared to have started around 10:48 GMT on 02/09, but was not really noticeable until slightly after 11 GMT, when tkair values dipped considerably. The dewblower was replaced on 2/11 and temperature readings returned to normal. |
