| Subject: | AWR/TSI/M1 - Reprocessed and Corrected: Sky filter thresholds |
|---|---|
| Affected Datastreams: | awrtsiskycoverM1.b1 |
| Description | DATA REPROCESSED and CORRECTED: The sky filter thresholds were incorrect causing poor fractional cloud cover values. The filter threshold thin_thresh was changed from 50 to 10 and opaque_thresh was changed from 70 to 90. The data were archived in July 2017. Please retrieve the reprocessed data for use in your analysis. You may find these data using the ARM Discovery tool at the following link: http://www.archive.arm.gov/discovery/#v/results/s/finst::tsi/ffac::awr.M1 ORIGINAL DQR CATEGORY: Red-Incorrect REPROCESSED and CORRECTED DATA ARCHIVED: 2017-07 REPROCESS IDENTIFICATION NUMBER: RID 1448 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- The sky filter thresholds incorrect. --------------------------------------------------- --- ORIGINAL DQR SUGGESTIONS --- --------------------------------------------------- The cldmask images and fractional sky cover values cane be reprocessed by changing the sky filter thresholds from thin_thresh=50 and opaque_thresh=70 to 10 and 90, respectively. |

|---|---|
| Affected Datastreams: | awrtsiskycoverM1.b1 |
| Description | The lid of the TSI enclosure was not secured properly on 9/23 allowing snow infiltration which caused the mirror control board to malfunction on 10/12 so the shadowband did not mask the sun. The TSI was shutdown on 10/14, brought inside on to thaw and dry out, and reinstalled on 10/15. |

|---|---|
| Affected Datastreams: | awrtsiskycoverM1.b1 |
| Description | The mirror became loose from the shaft, probably due to high winds and cold temperatures, so that the shadowband was not masking the sun. The mirror was secured and the shadowband realigned. |
