Subject:
TWP/TSI/C3 - poor images
DataStreams:twptsicldmaskC3.a1, twptsiskycoverC3.b1, twptsiskyimageC3.a1
Description:
The resolution of TSI images were very poor and the colors were wrong.  The clear sky 
appeared a reddish-brown during the day causing the processed image to be 100% opaque. The 
problem was corrected when the instrument was power cycled.
Suggestions: 
Measurements:twptsiskycoverC3.b1:
  • Pixel count: number total in sun circle(region.sun.count)
  • Pixel count: number total thin(count.thin)
  • Percentage thin cloud(percent.thin)
  • Sunshine meter(sunny)
  • Pixel count: number thin in zenith circle(region.zenith.count.thin)
  • Pixel count: number opaque in zenith circle(region.zenith.count.opaque)
  • Pixel count: box, outside mirror area(count.box)
  • Pixel count: number total opaque(count.opaque)
  • Pixel count: number total in zenith circle(region.zenith.count)
  • Pixel count: number total in processed circle(count.sky)
  • Pixel count: number total indeterminant(count.unknown)
  • Pixel count: number total between horizon and processed circle(count.sub.proczen)
  • Percent opaque cloud(percent.opaque)
  • Pixel count: number thin in sun circle(region.sun.count.thin)
  • Pixel count: number opaque in horizon area(region.horizon.count.opaque)
  • Pixel count: number total in horizon area(region.horizon.count)
  • Pixel count: number thin in horizon area(region.horizon.count.thin)
  • Relative \'strength\' of direct sun(sun.strength)
  • Pixel count: camera and sun strip mask(count.mask)
