MEGAN

Model of Emissions of Gases and Aerosols from Nature

Contact: Alex Guenther (alex.guenther@uci.edu)

MEGAN is a modeling system for estimating the emission of gases and aerosols from terrestrial ecosystems into the atmosphere. A brief history of the model and a list of publications are provided.

Additional background on biogenic emissions and information on MEGAN is available from the training course materials.

MEGAN in other models. In addition to the "stand-alone" code, MEGAN has been integrated into chemistry and transport models (CTMs) to generate on-line emission estimates and simulate coupled interactions. Each model has a different version/implementation of the MEGAN algorithms and different weather and landcover driving variables. As a result, the estimated emissions can differ considerably. An incomplete list of links to models that have incorporated some version of MEGAN includes the following:

WRF-Chem, CESM, MOZART, GEOS-Chem, ECHAM6-HAMMOZ, MALTE, SURFEX, Oslo CTM3, BRAMS, CSIRO-CTM
