The D-FIRE sub-project of MACC is producing real time fire emissions with a Global Fire Assimilation System (GFAS). The emissions will be used by the regional and global forecast production systems in MACC. The first version of the fire emission products, GFASv0, is based on the GEMS fire emission product but is scaled such that it reproduces the global annual emission budget of the GFEDv2 inventory. Preliminary comparisons of modelled smoke plumes with other systems' smoke plumes indicates that the GFASv0 products are applicable for fire plume forecasting. They are released with a previously agreed interface that consists of archiving in the MARS database of regular latitude-longitude emission fields for several species with 0.1 deg spatial resolution and 1 hour temporal resolution. The release enables the MACC partners to implement and technically test the interface. Furthermore, the fire emissions may already be used in the MACC forecasting systems after testing their effect on the particular system's forecasting skill. Feedback on the product interface as well as its performance in forecasting applications is encouraged.
