Government information must be easy to find, whether it is current or from the past. Old information can be important for our history and culture. In addition, both individuals and businesses can derive rights from information found on government websites. This is why old Dutch governmental web pages are archived.

Web archive

You can access the archive of the TROPOMI website via and then by selecting TROPOMI from the dropdown menu.

How the web archive works

You can use the web archive in two ways:

  • By selecting a date on the calendar (in the grey bar on the left of the screen) you can navigate through the site as it was on a specific day in the past. 
  • You can search through the site via the search field (under the calendar).
