Emission inventories: Area Source Data
Area Sources are dynamically instantiated OBJECTs
with the standard
object header 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:
In parallel, a MAP of the current domain with
the polygon representing each source location is shown.
- 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.
Data structure and data base representation
Please note: the attributes of an area source are an open list.
iANy Parameter that is defined as a DESCRIPTOR in the
systems knowledge base can be added dynamically
to the data base structure by adding a reference to the Descriptor to the
HTML TEMPLATE file that defines the OBJECT interface and editor.
