VACUMM - A Python Library for Ocean Science

VACUMM is an open-source Python library for processing data from observations and numerical models. The library is now used for several years in research and operational contexts, for instance for producing fi gures and reports, validating models, converting data, or making simple or advanced diagnostics. In this paper, we introduce how the library is built, and we present two applications of its use: one in an operational context and one in a research context.
