| Zusammenfassung |
We describe the Harvard–NASA Emission Component version 1.0 (HEMCO), a
stand-alone software component for computing emissions in global atmospheric
models. HEMCO determines emissions from different sources, regions, and species
on a user-defined grid and can combine, overlay, and update a set of data
inventories and scale factors, as specified by the user through the HEMCO
configuration file. New emission inventories at any spatial and temporal
resolution are readily added to HEMCO and can be accessed by the user without
any preprocessing of the data files or modification of the source code.
Emissions that depend on dynamic source types and local environmental variables
such as wind speed or surface temperature are calculated in separate HEMCO
extensions.
HEMCO is fully compliant with the Earth System Modeling Framework (ESMF)
environment. It is highly portable and can be deployed in a new model
environment with only few adjustments at the top-level interface. So far, we
have implemented HEMCO in the NASA Goddard Earth Observing System (GEOS-5) Earth system model (ESM) and in the
GEOS-Chem chemical transport model (CTM).
By providing a widely applicable framework for specifying constituent
emissions, HEMCO is designed to ease sensitivity studies and model
comparisons, as well as inverse modeling in which emissions are adjusted
iteratively. The HEMCO code, extensions, and the full set of emissions data
files used in GEOS-Chem are available at http://wiki.geos-chem.org/HEMCO. |
