The Harmonized Emissions Component (HEMCO)
The Harmonized Emissions Component (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] and Lin et al. [2021].
