Instrument Description

Identifying Information

Full Name: Heimann KT19 Infrared Radiation Pyrometer
Short Name or Acronym: KT19

Model if applicable: KT19.85

Measurements Made and Methods Used

Measurements Provided: Remote surface temperature
Manufacturer or Builder of the Instrument: Wintronics

When Acquired: 1994 (S/N 305, 756, 757, 93, 894), 1991 (S/N 305)

Operational Status: requestable, but has problems, needs work before deployment
- requestable, but has problems, needs work before deployment
General Description:
Measurement Characteristics:
- Overall estimate of uncertainty: 0.5K plus 0.7% of difference between scene temperature and sensor housing temperature
- Response time:
- Precision:
- Other measurement characteristics (comments on signal/noise, bias limits, etc):
  - Sample Rate = 5 Hz, Spectral Range = 9.6-11.5 microns, Field of View = 2 degrees

Calibration Methods: Calibrated in-house using the Eplab blackbody target over a range of temperatures from 1-40 degrees C
History of Significant Changes to the Instrument: Formerly temperature controlled for C-130 installations.

Description of Software, Data Handling, and Data Flow:
- Software Components (data acquisition, display, processing, and analysis): NIDAS, Aeros, Nimbus
- Data Processing Chain (from flight to archival): Calibrations applied in Nimbus. Post-project correction for contamination by atmospheric water vapor emission performed in special processing by request. Data follow the standard RAF path: Sampling and recording by the airborne data system NIDAS, post-flight processing by 'nimbus' and archiving along with other measurements in netCDF-format files. For more information on data handling, see this page: StandardDataPath.
QA Procedures and Needs: Review for effects of sensor temperature fluctuations. Radiative transfer modeling for atmospheric water vapor corrections

Safety Issues: none
