History of the BSRN quality checks
Quality checks using the BSRN-Toolbox
The quality of many BSRN data can be controlled individually by using the newest version of the BSRN Toolbox which was first released in 2012. The tool is rather flexible. It can handle:
- station-to-archive files freshly created by a station scientists prior to submission,
- files downloaded from the ftp-archive (ftp://ftp.bsrn.awi.de/),
- files downloaded from PANGAEA,
- files created via the DataWarehouse (for longer timeseries).
The quality checks offered by the BSRN Toolbox can help:
- the station scientists to test station-to-archive files before they get submitted,
- the data curator from the WRMC to perform quality checks before archiving the data (this gets done routinely since December 2011), and
- any user of the WRMC to test extracted data from the WRMC.
The quality checks are implemented into the BSRN Toolbox by Holger Schmithüsen. At the moment the BSRN Toolbox offeres the BSRN Global Network recommended QC tests, V2.0 from C. N. Long and E. G. Dutton. In the future, more qualitiy check options will be developed and implemented.

Other quality check initiatives
There are of course many other initiatives for quality checks of solar data, a few of them are listed here (you are free to propose additions, just write us an E-Mail):
