Investigating halocarbon impacts on the global environment (InHALE)

InHALE is a consortium project led by the University of Bristol, funded by the NERC under the Highlight Topics scheme.

The RAL Spectroscopy Group is involved in the WP 5.1 ‘Halocarbon radiative efficiencies and forcings‘ in collaboration with the University of Reading and the Scuola Normale Superiore in Pisa. As part of the activity, the RAL High Resolution Spectroscopy Facility was used to measure the far infrared (FIR) reference spectra of selected halocarbons (150 – 650 cm-1), their dependence in pressure and temperature, so that the reference spectral data can be used to calculate the atmospheric radiative forcing, currently poorly known in the FIR region.

The data can then feed into climate models to estimate more accurately the impact of halocarbon concentration change in the atmosphere. The data are also used to validate and support the development of ab initio calculations of halocarbon spectral properties in the FIR.

Who we are

The Spectroscopy Group of RAL Space carries out R&D on novel concepts and instruments for high-precision laser-based hyperspectral sensing, aiming to pioneer the development of the next generation of sensing systems needed for the demanding applications of atmospheric, space sciences, and beyond. It also offers a unique high resolution Fourier Transform facility to support many areas of science.
