Contemporary land use and land cover change impacts on global air quality

Abstract

Our work explores the impact of two important dimensions of land system changes, land use and land cover change (LULCC) and direct agricultural reactive nitrogen (Nr) emissions from soils, on ozone (O3) and fine particulate matter (PM2.5) air quality over contemporary (1992 to 2014) time scales. We account for LULCC and agricultural Nr emissions changes with consistent remote sensing products and new global emission inventories, respectively, estimating their impacts on global surface O3 and PM2.5 concentrations and Nr deposition using the GEOS-Chem global chemical transport model.

This repository contains the GEOS-Chem configuration files for each of our five simulations, in order to be able to reproduce identical simulation experiments.
