Analyzing planetary and heliophysics plasma data with AMDA: the last 20 years

We present AMDA, an online database and tool for analyzing plasma physics data. AMDA https://amda.cdpp.eu is developed and maintained by the French Plasma Physics Data Centre for 20 years and gathered a community of hundreds of users. It gives access to a variety of space plasma datasets in the planetary and heliophysics domains acquired by dozens of missions, such as Cluster, MMS, Rosetta, Solar Orbiter, and in a close future BepiColombo and Juice. The presentation offers a description of the architecture of AMDA including the interfacing with the Python library Speasy, describes its most recent functionalities notably statistical representation and catalogue management, solar wind predictions, access to remote simulation databases, and finally presents some use cases taken from the literature or recent collaborations.
