The European Space Agency maintains the MASTER space debris model and has multiple papers published on the topic.

There is a graph that I have seen in a few papers and on a few websites that I would like to obtain the raw data for to assist with my current research.


There is an entry for it in their multimedia archives here. However, there's no obvious link to obtain the raw data.

Would anyone have any idea where I could start on my search?

The data comes from DISCOS (Database and Information System Characterising Objects in Space).

You can get access here, but:

Users with a demonstrated need-to-know can apply for an account for on-line use (specified quotas apply) of DISCOS through a dedicated web-interface, if they belong to a research institute, to a government organisation, or to an industrial company of an ESA Member State (e.g., not as an individual).
