Agricultural Ammonia Emissions in South Asia for 2015

2015 gridded emissions data for ammonia (NH3) from agricultural sources across South Asia at 0.1-degree resolution. The dataset models emissions from five agricultural sub-sectors using bottom-up calculations based on activity data and emission factors. It was produced by the Environmental Information Data Centre using established IPCC and EMEP/EEA methodologies.

Use Cases

• Model atmospheric NH3 dispersion and deposition using the 0.1-degree gridded emission values for South Asia.
• Compare emission contributions from the five specified agricultural sub-sectors (CRB, CRR, MNM, GRM, SFA) across the region.
• Integrate 2015 agricultural NH3 emission grids as input for regional air quality or climate models.
• Analyze the spatial distribution of ammonia emissions from synthetic fertilizer application (SFA) versus livestock management (MNM).

Strengths

• Provides emissions data at a high spatial resolution of 0.1 degrees for detailed regional analysis.
• Emissions are disaggregated into five distinct agricultural sub-sectors for granular source attribution.
• Methodology is grounded in authoritative guidelines from IPCC, EDGAR, and EMEP/EEA.
• Dataset has a persistent digital object identifier (DOI) for citation and provenance tracking.

Limitations

• Data is limited to a single year (2015), preventing time-series or trend analysis.
• Spatial coverage is restricted to South Asia, limiting global or comparative studies.
• As a modeled, gridded product, accuracy depends on the underlying activity data and emission factors.
