DataStreams:twptsiC1.00, twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1
Description:
Water infiltrated the camera housing after periods of heavy rain causing moisture to

o-ring seal checked, and camera housing sealed where it joins the arm.

DataStreams:twptsiC1.00, twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskycoverC1.b1,

Description:
The TSI at Manus has been able to remain dry and produces an image but the percentage of 
cloud cover is determined to be 100% even on cloud free days. Moisture in the camera lens 
and neutral density filter was corrupting the sky images. The lens and filter were 
cleaned, the moisure seals checked, the camera housing sealed, and desiccant added to both the 
camera housing and main electronics enclosure. On 3/23/2006, the lens was replaced and 
the sky images were significantly improved.

TWP/TSI/C3 - controller board failure
DataStreams:twptsicldmaskC3.a1, twptsimovieC3.a1, twptsiskycoverC3.b1, twptsiskyimageC3.a1
Description:
The mirror control board failed and was replaced with a spare. Several images were 
collected in the iterim that should be ignored. These images include periods when the sun was 
not masked by the shadowband, the camera lens was covered by red tape to protect the CCD 
from direct exposure to the sun and, the instrument was inside the shop for repair and 
testing.

TWP/TSI/C1 - Shadowband continuosly rotating
DataStreams:twptsiC1.00, twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskycoverC1.b1,
twptsiskyimageC1.a1
Description:
The mirror was continuously spinning during different periods of the day, usually in the 
afternoon, causing the shadowband to not properly block the sun. This problem was 
corrected by removing the real-time-clock integrated circuit DSI306, or EEPROM U10, from the

TWP/TSI/C1 - rust spots on mirror
DataStreams:twptsicldmaskC1.a1, twptsiskycoverC1.b1
Description:
During the evening of 7/8/2006, something caused several rust spots on one side of the 
hemispheric mirror which continued to grow in size and to be interpreted as clouds in the 
processed images. This problem was corrected during a site visit when the mirror was 
replaced.

TWP/TSI/C1 - solar shadowband inoperative
DataStreams:twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1
Description:
The mirror/shadowband was not turning and there was no communication with the control 
board. The shadowband was stuck in the position of 0 degrees from 8/29 to 9/20/2006.

On 10/12/2006, the mirror was replaced, the real-time clock chip was removed and heat 
sinks were added to the control board, and the Ethernet hub and serial adaptor were replaced. 
On 1/8/2007, the slip clutch assembly, timing pulley, and timing belt were replaced 
(which were damaged when the mirror was replaced). These actions did not correct the problem. 
The instrument was swapped with the unit from Darwin so that the control board could be 
repaired and tested in Darwin.

Several images were collected in the iterim that should be ignored. These images include 
periods when the sun was not masked by the shadowband or the camera lens was covered by 
tape to protect the CCD from direct
exposure to the sun. There are also extended periods of missing data when the instrument 
was shutdown, waiting for parts.

TWP/TSI/C1 - hazy image
DataStreams:twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1
Description:
When the TSI from Darwin was installed (so the instrument from Manus could be returned to 
Darwin for repair) moisture in the camera lens and filter caused the sky image to be very 
"hazy". The U10 chip was removed from the control board, desiccant was installed inside 
the enclosure, additional small desiccant bags were installed inside the camera housing, 
the camera housing was sealed with silicon to prevent moisture ingress, and the camera 
lens filter was cleaned and the focus adjusted.

Description:
During this month there are a few intermittent instances of bad ambient temperature 
readings. I will summarize here these short time ranges:
20080909 between 02:00 and 03:00 UTC
20080909 between 09:00 and 14:00 UTC

Additionally the ambient temperature has short but frequent data gaps.  The data gaps are 
very short (less than one hour). Users could interpolate missing data or use alternative 
sensors such as the surface meteorological data available for the site.
