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.
Measurements:twptsiskycoverC2.b1:
  • Sun altitude above horizon(solar.altitude)
  • Sunshine meter(sunny)
  • Time offset of tweaks from base_time(time_offset)

twptsiskycoverC2.a1:
  • Time offset of tweaks from base_time(time_offset)

:

MPL
Ceilometer
MWR
WSI
TSI
