Abstract

The Quantifying the Amazon Isoprene Budget: Reconciling Top-down versus Bottom-up Emission Estimates project produced a unique high resolution model (GEOS-Chem version v8-03-01 - with modifications) for the Amazon, which simulated isoprene emissions and atmospheric chemistry. Model outputs associated with Barkley et al. publication is available through CEDA-BADC.

An evaluation of a nested high-resolution Goddard Earth Observing System (GEOS)-Chem chemistry transport model simulation of tropospheric chemistry over tropical South America is presented. The model has been constrained with two isoprene emission inventories:

(1) the canopy-scale Model of Emissions of Gases and Aerosols from Nature (MEGAN) and

(2) a leaf-scale algorithm coupled to the Lund-Potsdam-Jena General Ecosystem Simulator (LPJ-GUESS) dynamic vegetation model, and the model has been run using two different chemical mechanisms that contain alternative treatments of isoprene photo-oxidation.

Title Quantifying the Amazon Isoprene Budget: GEOS-Chem Chemistry Transport Model
Abstract GEOS-Chem Chemistry Transport Model. The nest-grid has a horizontal resolution of 0.667° × 0.5° (longitude × latitude), and 47 vertical levels extending from the surface to 0.01 hPa. The model is driven using GEOS-5 meteorology, which is updated every 3–6 hours. Tracer mixing ratios from an off-line global 4° × 5° simulation provide 3-hourly boundary conditions to the grid-edges. Based on a previous model evaluation [Barkley et al., 2011], we use an updated chemical mechanism to simulate O3-NOx-VOC-aerosol photochemistry.
