Edit Market Data

Market data are related to both, substances as well as areas (only catchments, not political or other areas) or points (discharge sites). To deal with this fact, a general consumption value is first loaded from the substance database on scenario creation or has to be entered for the substance in the substance dialog. More specifically, if edited, the general consumption value is representative for the scenario and therefore for the entire catchment. This general value can be overwritten by specifying market data for selected discharge sites.

When selecting the item Edit Market Data, the cursor shape changes to identify the new mode. After clicking on a discharge site, a dialog appears providing users with an entry to specify site-specific consumption data. To use the general consumption value, set the site-specific parameter back to `<none>` or switch the radion button to "use default".

To cover industrial sites, users can enter an additional input into the treatment plant. This input reflects discharges resulting from production processes and can be calculated from the production volume. Please note that the calculation of the fraction of the production volume which will be released is not part of GREAT-ER but must be calculated manually by hand beforehand.

The input considered here is the mass flow into the treatment plant in [kg/a]. As with loads from usual consumption, industrial input is processed by the treatment plant models. Market information is substance-specific and will therefore be stored as substance properties. This will be done in two lists, one containing the catchment-related market information and the other containing discharge-specific consumption/input.

After leaving the dialog, the market data tool is still active.
