Short summary

In this study, we integrated satellite constraints on atmospheric NH₃ levels and fire intensity, discrete NH₃ concentration measurement, and N isotopic analysis of NH₃ in order to assess the regional-scale contribution of biomass burning to ambient atmospheric NH₃ in the heartland of Southeast Asia. The combined approach provides a valuable cross-validation framework for source apportioning of NH₃ in the lower atmosphere and will thus help to ameliorate predictions of biomass burning emissions.
