In this paper we present the architecture of a distributed data storage for astroparticle physics. The main advantage of the proposed architecture is the possibility to extract data on both file and event level for further processing and analysis. The storage also provides users with a special service allowing to aggregate data from different storages into a single sample. This feature permits to apply multi-messenger methods for more sophisticated investigation of the data. Users can use both Webinterface and Application Programming Interface (API) for accessing the storage.

This paper provides a case study on satellite data processing, storage, and distribution in the space weather domain by introducing the Satellite Data Downloading System (SDDS). The approach proposed in this paper was evaluated through real-world scenarios and addresses the challenges related to the specific field. Although SDDS is used for satellite data processing, it can potentially be adapted to a wide range of data processing scenarios in other fields of physics.
