NEIVA is a biomass burning emissions inventory in which emission factors (EFs) for over 1500 constituents have been integrated and organized by 14 globally-relevant fuel and fire types. NEIVA builds on the 2011 EF compilation of Akagi et al., adding published data from recent laboratory and field studies. NEIVA has been structured to allow easy integration of new data and flexible querying based on user needs. NEIVA consists of a series of datasets that are linked using unique identifiers. All of the gaseous compounds have been mapped to model surrogates for widely-used chemical mechanisms to facilitate use of these data in air quality and climate modeling applications. EFs can be queried at the individual compound/fuel/study level to pollutant category/model surrogate/global fire type level. This GitHub repository includes data files and database design codes for data integration, processing, and querying.
