W. Aeschbach and colleagues
I have been involved in the development of software tools that help to interpret noble gas and other tracer data.
The software is available via the following links:
Modeling noble gas concentrations in (ground)water:
Inverse determination of model parameters by weighted least squares fitting.
There are three programs available: A simple MS EXCEL workbook, a more sophisticated MATLAB routine, and finally the very versatile, stand-alone program PANGA.
The old, simpler EXCEL workbook developed by myself is available here: Noblebook
The MATLAB routine developed by Frank Peeters is available at
There is new version available (since Dec. 2003), and an updated manual.
The new software PANGA developed by Michael Jung is available here: PANGA page.
Modeling age tracer data in young (ground)water:
Box-model approaches to interpret 3H(-3He), CFC, and 85Kr data.
The software "Boxmodel V3" is a MICROSOFT EXCEL workbook, designed for educational purposes. It has originally been developped by Kai Zoellmann, and later been expanded by myself and used for a UNESCO-workshop by Urs Beyerle. Workbook and documentation are provided here for free download.
Boxmodel_V3 workbook (3.8
MB MS-Excel file)
Boxmodel documentation (1 MB pdf-file).
Boxmodel.zip (1.1 MB zipped version of the above).
