QDOAS Technical support

The user manual provides some help to start an application and explains most options. It also gives a short description of the algorithms used, but we strongly recommend that beginners who have never worked with DOAS before read dedicated literature (for example: Differential Optical Absorption Spectroscopy. Principles and Applications, Ulrich Platt and Jochen Stutz, 2008).

QDOAS is not a commercial product. The software was developed and tested first for BIRA-IASB applications. Because of the large number of possible configurations, it is possible that some bugs remain for configurations with rarely used combinations of options. If you believe you have found a bug, please contact the authors (see below). In order to help us investigate the problem, please mention the version of QDOAS you are using, and, if possible, provide us with an example configuration, complete with all auxiliary data and some files for analysis.

Installation

Please refer to the user manual.

Known issues

The following issues are related to the the user interface.

  • Some error messages are incomplete or missing usually in case of wrong path or input file not found
  • Go up to previous spectra in the file using buttons of the tool bar blocks if one record doesn't reply to selection conditions; select the record number instead;
  • Overlay of spectra works only for data with the same number of points, not for partial spectra or xs
