IASI-derived ER[NH3/CO] in tropical biomass burning regions

A recent study by Whitburn et al. (2017) investigates the spatial and temporal variability in the biome-specific NH3 enhancement ratios relative to CO (ER_NH3/CO). They suggest a revision of the  ER_NH3/CO and emission factors for NH3 used in the bottom-up fire models and highlight the need for the development of dynamic ER_NH3/CO in order to reduce the large uncertainty on the NH3 emission from vegetation fires.
