Subject:
TWP/TSI/C1 - shadowband misalignment
DataStreams:twptsiskycoverC1.b1, twptsicldmaskC1.a1, twptsiskyimageC1.a1
Description:
The TSI mirror controller was configured with a north latitude instead of south causing 
the shadowband to not mask the sun beginning at the vernal equinox. The problem was 
corrected by changing the sign of the latitude in the configuration file.
Suggestions: 
Measurements:twptsiskycoverC1.b1:
  • Pixel count: number thin in sun circle(region.sun.count.thin)
  • Percent opaque cloud(percent.opaque)
  • Pixel count: number total in sun circle(region.sun.count)
  • Pixel count: number total opaque(count.opaque)
  • Pixel count: number total thin(count.thin)
  • Pixel count: number opaque in sun circle(region.sun.count.opaque)
  • Percentage thin cloud(percent.thin)
