Using the aerosol-analyzer

The aerosol-analyzer is a GUI application where one can visualize and analyze aerosol number size distribution data. The application runs in the browser using a bokeh server.

A general workflow is roughly the following:

1. Load aerosol number size distribution data from a CSV file. Note that it is recommended to first combine all the data into a single file before opening it in the aerosol-analyzer. In the CSV file:
   • First column: timestamps (e.g. in the format YYYY-MM-DD HH:MM:SS)
   • First row: particle diameters representing each size bin
   • The rest of the data should contain the number size distribution
2. Draw regions of interest (ROIs) on the number size distribution using the FreehandDrawTool
3. Select ROIs using the TapTool and do selected calculations on the data inside the ROIs. For example one can:
   • Fit (mixture) log-normal distributions on the selected size distributions
4. Save the ROIs including the calculated quantities to a JSON formatted file.
5. Continue working on a project by loading an already saved ROI file.

To start the application type on the command line:
