Subject: | GRW/SKYRAD/M1 - Tracker inoperative |
DataStreams: | grwskyrad20sM1.a0, grwskyrad60sM1.b1 |
Description: | The solar tracker arms were caught and pulled way out of alignment. Problem corrected by OPs at 0815Z May 11th. All bolts tightened and alignment and tracking checked. Down_short_hemisp_diffuse (8-48 instrument)is incorrect and not recoverable. short_direct_normal (NIP instrument) is suspect during this time as well. down_short_hemisp (PSP instrument) was unaffected. |

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/MWRP/M1 - Reprocessed: Updated calibration coefficients |
DataStreams: | grwmwrpM1.b1 |
Description: | On 5/15 the K-band calibrations were updated with coefficients derived from tip curves. The 20090501-20090515 data were reprocessed to apply the updated calibration coefficients. |
