The state of affairs
Number of stations
At present, 52 BSRN stations are in operation, 7 stations are temporarily or permanently closed. The stations measure different sets of radiation values. Some stations carry out only 'basic measurements' (see Update of the Technical Plan for BSRN Data Management) or the measurements list. Other stations carry out 'other measurements' in addition to the 'basic measurements'. Part of the stations also perform synoptic observations, upperair soundings, ozone measurements and 'expanded measurements'.
The establishment of additional stations is in preparation. Some of these stations should be in operation within the current year.
The BSRN database is based on PANGAEA. This Data Publisher for Earth & Environmental Science is an Open Access library aimed at archiving, publishing and distributing georeferenced data from Earth system research. Data can be found by using the PANGAEA search engine or through links on this web pages. The data description (metadata) of all data sets are visible and include the principle investigators (PI) name and email for contact. The on-line data access is offered to anybody who accepts the data release guidelines (please contact Gert König-Langlo.)
Additionally to the web-based PANGAEA access the original station-to-archive files (without derived quantities and quality flags) can be obtained via the ftp-server:ftp.bsrn.awi.de. Again, for data access please contact Gert König-Langlo.
