A simplified isoprene oxidation mechanism for fast formaldehyde-based emission inversion of isoprene

Glenn-Michael Oomen, Jean‐François Müller, Trissevgeni Stavrakou, Isabelle De Smedt et autres

We introduce the Simplified Isoprene Chemistry for MAGRITTE (SICMA), a compact chemical mechanism designed for computationally efficient global chemistry transport modeling of formaldehyde (HCHO) and adjoint-based emission inversions. The scheme reduces the isoprene oxidation network of the MAGRITTEv1.2 model from 93 organic …

Satellite quantification of enhanced methane oxidation applied to the stratospheric plume following Hunga Tonga-Hunga Ha’apai eruption

Maarten M. J. W. van Herpen, Isabelle De Smedt, Daphne Meidan, Alfonso Saiz-Lopez et autres

Methane is a powerful greenhouse gas whose atmospheric sink remains uncertain, and emerging strategies to enhance its removal will require quantification and monitoring to verify any hypothetical future methane removal. Here we present satellite quantification of enhanced atmospheric methane oxidation, based on …
