Particulate Nitrate Emissions from Plumes over North China, 2019

Quantified plume primary nitrate emissions over North China for January and August 2019. The dataset includes a source-profile database for filterable emissions and a condensable particulate matter inventory across 9 anthropogenic sectors. It was created by Yuanzhe Ni and published on figshare in 2026.

Use Cases

• Improving chemical transport model performance based on quantified plume primary nitrate contributions.
• Analyzing sector-specific contributions to particulate nitrate emissions based on the 9-sector inventory.
• Assessing the impact of condensable particulate matter on near-surface nitrate concentrations based on WRF-CMAQ simulation results.
• Refining nitrate mitigation strategies based on the identified missing emission source from industrial and power plumes.

Strengths

• Includes a China-specific source-profile database for filterable particulate nitrate.
• Quantifies emissions for two distinct seasons (January and August 2019).
• Provides a condensable particulate matter inventory across 9 anthropogenic sectors.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is limited to two months in 2019 and the North China region.
