All data in the BSRN database are consistent. The radiation data however may be afflicted with error,
though their quality was controlled by the station scientists. Therefore at the WRMC, automated quality
control procedures are applied to the radiative flux data to detect erroneous values which subsequently
are flagged. The radiation data flagged at the WRMC as being afflicted with error and the reason for
the flagging are reported to the station concerned. If the station scientist judges the flagged and/or
other data to be questionable, he/she re-evaluates the monthly data set and forwards the new version
to the WRMC. The WRMC processes updated versions of the monthly data sets in the same way as
the original data sets, except that the older data are deleted from the database. Thus the BSRN database
always contains the radiation data judged to be most reliable.
The data in the BSRN database are available to the BSRN station scientists (and to external
scientific institutions after a certain delay) in archive-to-user files which are requested by means
of a WWW-interface.
The integration of consistent station log data, high-quality radiative flux data and auxiliary
atmospheric data in the BSRN database run by the WRMC enables an efficient production of
datasets meeting the objectives of the BSRN project.
