TOAR Data Publications
**********************


The data which has been sent to TOAR by individual organisations and has been processed as described above can be published via the TOAR publication service. The preparation of the data to be published is done by the TOAR data team. Technically the data publication is done with EUDAT’s B2SHARE service (https://b2share.fz-juelich.de/communities/TOAR). The TOAR data publication service prepares the metadata required by B2SHARE for the data set to be published. All TOAR data publications are released as open data under the Creative Commons - By Attribution (CC-BY 4.0) license (see https://creativecommons.org/licenses/by/4.0/).

As part of the data curation and ingestion workflow, we implemented tools which allow for automatic generation of a B2SHARE metadata record and the data upload. This will generate citable data publications, which can be used by the data providers or other users to unambiguously refer to individual data submissions or collections of measurements at individual observing sites. 

There are two types of collections which can be published in this process, the “Single Station Collection” and the “Single Station Series”:

:*Single Station Collection*: The publication contains  a set of data files with multiple measured variables at one specific station during the time period the station was in operation. An example is available at https://b2share.fz-juelich.de/records/f4e3583024e84467aa7c2d24d5f4861d 


:*Single Station Series*: The publication contains a set of data files containing a time series with one measured variable at one specific station during a given time period. It is part of a Single Station Collection. An example is available at https://b2share.fz-juelich.de/records/d5ae0c08311e4b51965fcb7a7a922850

TOAR data publications consist of rich metadata, which are a combination of generic B2SHARE metadata and TOAR-specific enhancements. For an up-to-date listing of the metadata refer to https://b2share.fz-juelich.de/communities/TOAR. The metadata of station time series data files attached to TOAR data publications are described in :doc:`submission-format`.
