PriSpecTemp
The project will integrate knowledge and infrastructure in spectroscopic thermometry across the EU, and will improve, standardise and implement new non-contact methods, including primary ro-vibrational spectroscopic thermometry.

Accurate measurements of air temperature are essential for climate monitoring.
Spectrometric thermometry probes the thermodynamic temperature of gases, overcoming several practical challenges associated with contact thermometry in air and industrial processes.
The project will integrate expertise and infrastructure in spectroscopic thermometry throughout Europe, improving, standardising and implementing new non-contact primary methods, including ro-vibrational spectroscopic thermometry. These will be cross-validated against other non-contact and ITS-90 standard methods. The result will be a new hybrid calibration service with minimal long-term drift, supporting SI-traceable calibration of traditional contact thermometers in gas and air.
The Norwegian Metrology Service (JV) leads Work Package 3 of the project in addition to participating in scientific collaboration. This includes thermal analysis of gas cells for spectroscopy setups, modelling and uncertainty analysis. JV will also design and construct an optimised gas temperature measurement cell used to evaluate contact thermometers. Later in the project, this gas cell will be used to develop a prototype for the hybrid calibration facility.
PriSpecTemp began in September 2023 and will conclude in September 2026.
