Subject:	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: Time offset of tweaks from base_time(time_offset) Sun altitude above horizon(solar.altitude) Sunshine meter(sunny) twptsiskycoverC2.a1: Time offset of tweaks from base_time(time_offset)
