The model is a collection of ArcGIS raster calculations, originally implemented in VBA for ArcGIS 9.x; as this environment is obsolete, the author recommends to develop the calculations anew just by picking the syntax from the reports. Anyway, the value of the work is in the data and concept more than in the original scripts. In order to facilitate running calculations, all formulas for the European scale version are in a 'formulas.cfg' file (search either in the catalogue within the project MAPPE the 'Formula' Dataset, or in the FTP folder under \MAPPE\MAPPE_Europe\LATEST the file 'formula.cfg').
Finally, also an Excel workbook with a list of chemicals and associated physic-chemical properties that can be used as a starting point for calculations is provided, (this dataset, search also in the FTP folder under \MAPPE\MAPPE_Europe\LATEST the file 'chemicals.xls').
