Emission inventories: Point Source Data

The point Sources are dynamically instantiated OBJECTs with the standard object header data.

The Point Source Summary Page provides a summary view and statistical analysis of all point 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.

The data reported include:

  • The total number of point sources, split into: industrial plants (boilers and stacks); small stacks;
  • The last modification date of any one entry;
  • Stack parameters: average, minimum and maximum stack height;
  • Sum of emissions by substance over all sources, total and grouped into the two stack groups (industrial plants versus small stacks):
    • 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).
  • Number of industrial plants
  • Distribution of source numbers and emissions (user selectable, default is SO2) by SOURCE TYPE, shown as pie charts.
In parallel, a MAP of the current domain with a symbol at each source location is shown.

Data Base Representation

Please note: point sources are OBJECTS, that have an OPEN data structure, driven by the HTML TEMPLATES that define the display and editing of the object. The list below corresponds to the current (default) implementation. For all DESCRIPTORS, the set of valid symbols, valid numerical range, and unit are defined in the systems Knowledge Base.
