Step 1 : Please choose the csv file(s) for the analysis

Choose your file(s)...

Warning ! Please choose only csv file(s) with the same separators.

Step 2 : Please choose a separator for your file(s)

Warning ! You can select only one separator for all files.

Step 3 : Please specify the sensor name(s) associated to the file(s)

Warning ! The names has to be in the order of selected files and separated by ';'.

Step 4 : Please select start and end dates for analysis

Start date

End date

Warning ! If dates are selected they need to be include in the csv files.

NB : If no date is selected, this application will take into account dates of the files. If you only select the start or end date, the application will take into account the start or end date of the files.

Step 5 : Please choose pollutants that you want to analyse (thresholds for Europe pre-selected)

Apply ACC thresholds (24h and yearly thresholds, multi-threshold VOCs, etc.)
