| − | The clean and flexible reimplementation of the Kinetic PreProcessor package (aka KPP)—known as '''FlexChem'''—is nearing full integration into GEOS-Chem. Most of the remaining FlexChem development work will focus on replacing legacy infrastructure—which prevents GEOS-Chem from operating efficiently in high-performance computing (HPC) environments—with newer, more efficient algorithms.
