This repository (https://github.com/geoschem/HEMCO) contains the Harvard-NASA Emissions Component (HEMCO) source code. HEMCO is a software component for computing (atmospheric) emissions from different sources, regions, and species on a user-defined grid. It can combine, overlay, and update a set of data inventories ('base emissions') and scale factors, as specified by the user through the HEMCO configuration file. Emissions that depend on environmental variables and non-linear parameterizations are calculated in separate HEMCO extensions. HEMCO can be run in standalone mode or coupled to an atmospheric model. A more detailed description of HEMCO is given in Keller et al. (2014).
