Data management at the Oulu cosmic ray station
2021
With the recent electronics upgrade of Antarctic neutron monitors (NMs) DOMC and DOMB in 2019, the Oulu
cosmic ray station (Sodankyla Geophysical Observatory, Finland) receives a significantly larger amount of
data than before. This has led to a need for an important upgrade of the configuration of servers working at
the station. The new configuration has three types of servers: a web-server, a datamaster server and data
acquisition machines. The web-server provides a user interface for services of the station: the main website,
the GLE database and other services. The datamaster is the main server, which stores all data in raw files and
a database. Data acquisition machines are computers that directly receive data from the instruments and send
the files farther to the datamaster server. This work describes technical details of the cosmic ray station setup
providing reliable and secure data acquisition, handling and publication.
