Study compares optimisation and Bayesian methods for atmospheric reaction rates
A new arXiv preprint examines how well different optimisation and Bayesian inference techniques constrain reaction rate coefficients in detailed atmospheric chemical mechanisms. The work focuses on autoxidation systems, where many reaction pathways are only observed indirectly through high-resolution mass spectrometry data. The authors assess which methods best handle this indirect, uncertain evidence when estimating rates.
