The lead centre has prepared a collection scheme for meta-data related to GRUAN measurements. All information describing sites, measuring systems, and measurements will be collected with well-defined XML files and stored in a meta-data base at the lead centre. There are comfortable tools available programmed in Java for generating and submitting the GRUAN meta-data (GMD) files.
The lead centre has prepared a manual describing in detail which and how data and meta-data will be collected. This manual is attached to this blog and open for discussion.
Additionally, a short guide was drafted which explains the major steps for generating and submitting meta-data. This guide is also available here. Feedback of any kind is welcome.
The data-flow schemes and tools are currently tested in Lindenberg and during the CIMO radiosonde inter-comparison campaign in China. After this testing and discussion phase we will start asking stations to submit data according to that scheme in September.
