    An online emission module for atmospheric chemistry transport models: implementation in COSMO-GHG v5.6a and COSMO-ART v5.1-3.1 by M. Jähn, G. Kuhlmann, Q. Mu, Q. Mu, J.-M. Haussaire, D. Ochsner, K. Osterried, V. Clément, V. Clément, D. Brunner

    Published 2020-05-01
    “…<p>Emission inventories serve as crucial input for atmospheric chemistry transport models. To make them usable for a model simulation, they have to be pre-processed and, traditionally, provided as input files at discrete model time steps. …”

    An intercomparison of CH3O2 measurements by fluorescence assay by gas expansion and cavity ring-down spectroscopy within HIRAC (Highly Instrumented Reactor for Atmospheric Chemistry) by Onel, L, Brennan, A, Gianella, M, Hooper, J, Ng, N, Hancock, G, Whalley, L, Seakins, PW, Ritchie, GAD, Heard, DE

    Published 2020
    “…Simultaneous measurements of CH3O2 radical concentrations have been performed using two different methods in the Leeds HIRAC (Highly Instrumented Reactor for Atmospheric Chemistry) chamber at 295 K and in 80 mbar of a mixture of 3:1 He∕O2 and 100 or 1000 mbar of synthetic air. …”

    An Adaptive Auto‐Reduction Solver for Speeding Up Integration of Chemical Kinetics in Atmospheric Chemistry Models: Implementation and Evaluation in the Kinetic Pre‐Processor (KPP) Version 3.0.0 by Haipeng Lin, Michael S. Long, Rolf Sander, Adrian Sandu, Robert M. Yantosca, Lucas A. Estrada, Lu Shen, Daniel J. Jacob

    Published 2023-02-01
    “…Abstract Kinetic integration of large and stiff chemical mechanisms is a computational bottleneck in models of atmospheric chemistry. It requires implicit solution of the coupled system of kinetic differential equations with time‐consuming construction and inversion of the Jacobian matrix. …”
