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.

DataStreams:twptsiC2.00, twptsicldmaskC2.a1, twptsimovieC2.a1, twptsiskycoverC2.b1,
twptsiskyimageC2.a1
Description:
The operation of the camera was itermittant. It produced very poor "hazy" images, blank 
white images, or no images when the camera failed to respond. Several attempts were made to 
correct the problem, involving checking the power and ethernet connections and wire and 
cleaning the lens and filter. The camera was replaced by a spare.

Description:
The indicated dome temperature and heat sink temperature were unreasonably high. The 
control board and serial adaptor were replaced and the instrument was shipped to Darwin for 
repair where the following was performed: 
- changed out 12V battery, 
- changed out faulty TT8 processor s/n 939476 with spare s/n 939476, 
- installed new model Lantronix EDS1100 serial to ethernet adapter,  
- modified board to adapter data connection to suit new adapter, 
- changed out two faulty temperature sensors (heatsink and dome), 
- changed out corroded heatsink fan and faulty wiring, 
- replaced damaged heater wiring, 
- removed corrosion and re-painted camera bracket, 
- waxed and polished dome mirror and whole instrument body.
