NSA/IRT/C1 - Serial communication problem
DataStreams:nsairt200msC1.a1, nsairtC1.b1
Description:
Data acquisition was intermittent due to poor serial communication, causing many gaps in 
the datastream.

Subject:
NSA/IRT/C1 - Data acquisition problem
DataStreams:nsairt200msC1.a1, nsairtC1.b1
Description:
Serial communication errors resulted in incomplete raw data resulting in incorrect 
processed data records. Response strings from the IRT were occasionally not parsed correctly 
causing a much smaller value of temperature (for example, '29' instead of '294.6') to be 
recorded.

The acquistion program was updated to improve communication with the IRT.
Measurements:nsairt200msC1.a1:
  • IR Brightness Temperature(sky_ir_temp)
nsairtC1.b1:
  • sky_ir_temp_std
  • sky_ir_temp_max
  • sky_ir_temp_min
  • IR Brightness Temperature(sky_ir_temp)
