TWP/TSI/C3 - Missing data due to Mentor Activities
DataStreams:twptsiC3.00, twptsiskycoverC3.a1, twptsiskycoverC3.b1, twptsiskyimageC3.a1
Description:
Darwin TSI on-board image collection and processing
had been turned off for Instrument Mentor to make
fine tuning adjustments. Mentor then forgot to turn
the on-board image collection and processing back
on.  All data for this time period is missing and
unrecoverable.

TWP/TSI/C3 - Metadata Errors in NetCDF Header
DataStreams:twptsiskycoverC3.a1, twptsiskycoverC3.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.
Measurements:twptsiskycoverC3.a1:
  • time_offset

  • time_offset
  • solar.altitude
