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/C2 - Mirror continuously rotating
DataStreams:twptsicldmaskC2.a1, twptsimovieC2.a1, twptsiskycoverC2.b1, twptsiskyimageC2.a1
Description:
The mirror began to continuously spin. Diagnostics were performed on the encoder, control 
board, and Ethernet adaptor. The instrument was removed on 1/2/2008 and shipped to Darwin 
for repair. The encoder and control board were replaced and the instrument was 
reinstalled.

TWP/TSI/C2 - Shadowband Misalignment
DataStreams:twptsiskycoverC2.b1
Description:
The shadowband was not masking the sun beginning at sunrise because the control board had 
the wrong date & time. These were reset and the shadowband came into proper alignment.
Measurements:twptsiskycoverC2.b1:
  • Sun altitude above horizon(solar.altitude)
  • Solar azimuth angle(solar.azimuth)
  • Pixel count: number thin in sun circle(region.sun.count.thin)
  • Percentage thin cloud(percent.thin)
  • Pixel count: number total thin(count.thin)
  • Pixel count: number total in sun circle(region.sun.count)
  • Pixel count: number opaque in sun circle(region.sun.count.opaque)
  • Percent opaque cloud(percent.opaque)
  • Pixel count: number total opaque(count.opaque)
