Archive Status and Neumayer

Since July 2008, the World Radiation Monitoring Center (WRMC) is hosted at the Alfred Wegener Institute (AWI) of Polar and Marine Research at Bremerhaven, Germany (see http://www.bsrn.awi.de). In mid 2014, 58 BSRN stations submitted their data to the WRMC. The data import is organized in so-called “station-to-archive files” which contain all the data from one station collected during one month. There have been a total of 7825 station-month data sets from 58 stations collected in the WRMC in September 2014. All submitted station-to-archive files are read-accessible from any user who accepts the BSRN data release guidelines (see http://www.bsrn.awi.de/en/data/conditions_of_data_release/). The files can be obtained via ftp://ftp.bsrn.awi.de/ by using a web browser or any ftp tool. The access to the public file archive is password-restricted. Read accounts can be obtained from the WRMC (email Gert.Koenig-Langlo@awi.de). An alternative to the ftp access is a data access via the Publishing Network for Geoscientific and Environmental Data, PANGAEA (see http://www.pangaea.de/) which offers much more user-friendly services. Since December 2011 the WRMC also checks the quality of all incoming data. The station scientists are recommended to test their data prior to submission using e.g. the BSRN-Toolbox (http://wiki.pangaea.de/wiki/BSRN_Toolbox). An updated Technical Plan for BSRN Data Management is now available via the BSRN webpage or www.wmo.int/pages/prog/gcos/Publications/gcos-174.pdf. The BSRN measurements at Neumayer are ongoing. They are part of a much bigger observatory program which includes synoptic observations, upper air soundings, ozone soundings, and surface air chemistry measurements. Radiation data from an automatic weather station (AWS) which run one year directly besides the BSRN measurements were analyzed to quantify typical errors of unmanned systems in Antarctica.
