Plume Particulate Nitrate Emissions over North China, January and August 2019

Yuanzhe Ni compiled a dataset quantifying filterable and condensable primary particulate nitrate (P-NO3–) emissions from plumes over North China. The data was generated by integrating a sector-specific emissions framework, oxygen-isotope constraints, and WRF-CMAQ sensitivity simulations for January and August 2019. It includes a China-specific source-profile database and a condensable particulate matter inventory across 9 anthropogenic sectors.

Use Cases

• Improving chemical transport model performance based on quantified primary nitrate emissions.
• Analyzing sectoral contributions to air pollution based on the inventory across 9 anthropogenic sectors.
• Assessing seasonal variation in nitrate concentrations based on data for January and August 2019.
• Validating emission inventories using oxygen-isotope constraints mentioned in the description.

Strengths

• Includes a constructed condensable particulate matter inventory across 9 anthropogenic sectors.
• Quantifies plume primary nitrate emissions, with the condensable fraction reported as 91.5%.
• Data is specific to North China and uses a China-specific source-profile database.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Temporal coverage is limited to two months (January and August 2019).
