Our Mission

EBAS is a database infrastructure developed and operated by NILU – Norwegian Institute for Air Research. It is designed to document, quality assure, secure long-term storage and provide users for access to  atmospheric composition data generated by international and national frameworks and research projects.

Data policy and acknowledgement

EBAS hosts data submitted by data originators in support of a number of national and international programs ranging from monitoring activities to research projects.  

Data availability and data policy issues:

All datasets in EBAS are associated to one or more projects, having individual rules for data disclosure.

The project association is normally set by the data originator through the submission process.  

Public data

Most of the data stored in EBAS are originating from programs encouraging an unlimited and open data policy . For scientific purposes, access to these data is unlimited and provided without charge. By their use you accept that an offer of co-authorship will be made through personal contact with the data providers or owners whenever substantial use is made of their data. In all cases, an acknowledgement must be made to the data providers, to EBAS/NILU and to the Framework/project name. Public data are available without login.

Data with restrictions

Access to restricted data requires the user to approve the associated data policy. The approval process which follows may in simple cases be an automatic procedure where the users by default is granted access (a log of signed data policy agreements is stored at NILU), or in more restricted cases will the request be handled by an authorized person on behalf of the formal deciding body of the respective project.

For more information about data policies associated to the projects with data stored in EBAS, please visit the “info” page which is available from the projects search filter. Here one can also find information whether the data stored in EBAS represents a primary database or if they are a secondary copy. It also informs if NILU has a mandate to conduct QAQC efforts related to the data.
