Subject: | MAG/TSI/M1 - Water on lens |
DataStreams: | magtsiskycoverM1.b1 |
Description: | After a rain episode, drops of water collected on the lens window causing the cloud fraction values to be suspect. To prevent this, a drip edge was formed around the bottom of the enclosure with thick electrical or splicing tape. |

Subject: | MAG/TSI/M1 - Shadowband misalignment |
DataStreams: | magtsiskycoverM1.b1 |
Description: | The mirror was not being controlled correctly so the shadowband did not block the sun because the encoder failed. Also, the shadowband was not correctly positioned in the processed image while at port because the INS system failed. On 10/19 while at Long Beach port, the encoder was replaced and software was installed to get the mirror control board to receive the SeaNav data and correctly position the shadowband to mask the sun in the visible image. However, the position of the shadowband in the processed image was not correct because the imaging software needed to be configured to independently read the SeaNav information. On 11/8 while at Honolulu port, the TSI software was upgraded at 17:10 and the position of the shadowband in the processed image was corrected. However, because SeaNav failed and course-over-ground was being used as a surrogate for heading, the heading is 0 deg when the ship speed is < 1 m/s. So the platform heading was changed manually at 17:45 to correct the position of the shadowband in the visible image while the ship was in port. This method was used by the site technicians to configure the TSI upon arrival and departure at port until the ship navigation system was replaced on 12/7 at 9:00. The $TSINV heading value became accurate while in port so the position of the TSI shadowband was automatically controlled correctly both at sea and at port. |

Subject: | MAG/TSI/M1 - Ship mast in field-of-view |
DataStreams: | magtsiskycoverM1.b1 |
Description: | The mast of Horizon Spirit cargo ship was in the field-of-view of the TSI and contributed to the calculated fractional sky cover amount (i.e. the ship's mast was interpreted as a cloud). This effect is most apparent during clear sky periods and negligible during overcast periods. An algorithm will be developed to remove the contribution of the ship's mast to the fractional sky cover determination. |

Subject: | MAG/AOS/ALL/M1/S1/S2 - Ship in port |
DataStreams: | magtsiskycoverM1.b1 |
Description: | The ship was in port during these periods and the measurements may be affected by various sources (overhead cranes, anthropogenic sources, etc). Note: Dates and times were found by looking at the NAV datastream. The standard deviation of pitch, roll, and surge velocity were used to determine when the ship was slowing down to enter port or speeding up to leave port. Thresholds used; pitch (0.01), roll (0.01), surge velocity (3.0) |
