TWP/TSI/C2 - Metadata Errors in NetCDF Header
DataStreams:twptsiskycoverC2.a1, twptsiskycoverC2.b1
Description:
The value of "sample_int" reported in the netCDF header is
incorrect.  The correct sampling interval is 30 seconds.

The maximum values for the variable "sunny" is incorrect.  
It should be 1, not 100 as documented in the netCDF header. 
Users should disregard the "qc_sunny" flag during this
period of time and apply their own qc check if desired.

The minimum value for the variable "solar.altitude" is
incorrect. It should be -90, not 10 as documented in the
netCDF header.  Users should disregard the "qc_solar.altitude"
flag during this period of time and apply their own qc check
if desired.

TWP/TSI/C3 - camera failure
DataStreams:twptsiskycoverC3.b1, twptsiskyimageC3.a1
Description:
The TSI image was out of focus due to condensation on the camera lens and PC board that 
led to camera failure. The problem was corrected by replacing the camera with a spare and 
adjusting the shadowband.

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 
control board and reloading the position and time parameters.

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 - high control board temperature
DataStreams:twptsiskycoverC1.b1
Description:
The TT8 control board temperature was high, ~50C, so that the cooling fan was constantly 
on. It appears that the heat sinks were not transferred from the original board to the new 
one when it was replaced. The problem was corrected when heat sinks were installed.

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 - shadowband misalignment
DataStreams:twptsicldmaskC1.a1, twptsiskycoverC1.b1, 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.
