All data in the BSRN database are consistent. The radiation data however m ay be afflicted with error,
though their quality was controlled by the station scientists. Therefore at the W RMC, autom ated quality
control procedures are applied to the radiative flux data to detect erroneous values which subsequently
are flagged. The radiation data flagged at the W RMC 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 m onthly data set and forwards the new version
to the W RMC. The W RMC processes updated versions of the m onthly data sets in the sam e 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 m ost 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 m eans
of a W W W -interface.
The integration of consistent station log data, high-quality radiative flux data and auxiliary
atm ospheric data in the BSRN database run by the W RMC enables an efficient production of
datasets m eeting the objectives of the BSRN project.
