Working with IAMM.

  • Create project with IAMM model chain.

  • Right click at the task in the created project and press init.

  • There are 2 ways of initializing the project:
  • Init using control file.
    Go to IAMM menu “Control File” → “Open”. And select prepared file with extension “.cro”.
    In this case the data is taken from files, specified in the control file, and database will be loaded to gui.
  • Init using GUI.
    Data should be entered to the following tabs.
    1. “Project” tab
      Specify Start time of pollution process and time of the resulting map. Map time should be later then Start time.
      There are two options to import measurements. The first is loading from file and the second is loading from database. Measurements taken at times between start and map dates and from specified provider are loaded from the database. If there is no measurements satisfying these requirements in the database, the notification label is displayed. If you want to import measurements from file you need to prepare a file according to the IAMM measurement file format specification. Then either import it via Rodos menu (“Measurements → Import Measurements”) or directly form IAMM initialization panel.

      Select regionalization method, mapped quantity and operation mode.
      If “interpolation with uncertainties” is selected then it is possible to specify types of uncertainties.

      Mesh can be imported from prepared project file or generated.

      Also map selection tool is available to specify the lower left corner and size of the domain. Press “Select on map” button to use it.

      After selecting domain you can check its properties at “Project” tab.
      Then fill in “step x” and “step y” fields or change size of the domain. Domain lengths are automatically adjusted in order to contain whole number of steps. Make sure that selected domain contains measurement points. Coordinates in the IAMM measurement files are geographical longitudes and latitudes.
    2. “Nuclides” tab
      Select prepared file with extension “.nuv”. Then select nuclides for which maps should be generated using the tool shown below.If “All” is selected, additional map for the sum of all nuclides will be generated.
    3. “Location Factors” tab
      Location factors from RTDB are shown here. You can modify existing or add new location factors by pressing button “Edit location factors”. Default location factor corresponds to lawn, dry.

      You can assign new location factors using map selection tool which is activated by pressing the “Assign location factors” button.

      Use toolbar to select current action or return to initialization tabs. Combobox is used to select current location factor. It becomes enabled after pressing the first button (count from left to right). Second button is used to assign default location factor (dry, lawn), it is done by clicking on the measurements on map. And the third button is used to return to initialization tabs.
    4. “Data Assimilation” tab
      Not implemented.
  • Press “Submit” button. It will be enabled if all necessary data is entered.
  • Right click on inited task in the project explorer and press “Run”.
  • After the model is finished you can view results on map or as a table.
    The results are stored in “Results” folder at the project explorer.
