Emission inventories: Area Source Data

The Area Source Summary Page provides a summary view and statistical analysis of all area sources in the inventory, grouped or filtered by the domain selected, starting with the default domain. The domain provides the geographical definition of a (sub)area of interest. If there are only a few area sources in the domain, each partial source is considered by intersecting its area with the domain boundaries and calculating a pro-rata, area weighted partial emission contribution; if there are numerous (more then 100) area sources in the domain, only those completely included are considered.

The data reported include:

• The total number of area sources within the domain;
• The total (sum of individual sources) area, percentage of the domain area, average, minimum and maximum size of areas;
• The last modification date of any one entry;
• Sum of emission by substance over all sources, total and grouped into the source SECTOR groups: industrial, commercial, residential, public, and traffic.
  • SO2 emissions (total, average, max);
  • NOx emissions (total, average, max);
  • CO emissions (total, average, max);
  • PM-10 and PM-2.5 emissions (total, average, max);
  • VOC emissions (total, average, max).
• Distribution of source numbers and emissions (user selectable, default is SO2) by SOURCE SECTOR , shown as pie charts.
