Full Name: Ophir III Air Temperature Radiometer
Short Name or Acronym: Ophir
Model if applicable:
Measurements Provided: Radiometric air/cloud temperature
Manufacturer or Builder of the Instrument: Ophir Corp.
When Acquired: Prior to 2002.
Operational Status:
obsolete, should be or is retired: This is being replaced by the "In-Cloud Radiometric Temperature" instrument now (2012) reaching readiness for deployment.
General Description:
Calibration Methods: Calibration constants determined by least-squares fit to ATX, typically on a per-project basis.
History of Significant Changes to the Instrument: None since 2002.
Description of Software, Data Handling, and Data Flow: Internal processing code by Ophir Corp. Output is ASCII stream over RS232 containing reference temperatures and detector signal from which radiometric air temperature is calculated in nimbus.
Software Components (data acquisition, display, processing, and analysis): Internal code, nimbus
Data Processing Chain (from flight to archival): ASCII stream to aircraft data system, calculation of radiometric air temperature (OAT) in nimbus. Stored in flight netcdf file.
QA Procedures and Needs: Calibration constants determined by least-squares fit to ATX, typically on a per-project basis.
Safety Issues:
