Upload

All registered users can upload files. Uploads intended for GEOCARBON should ideally confirm to the following rules:

• Data should be provided as netCDF-Files.
• The file format has to stick to CMIP5 conventions wherever possible (cf. for a description http://cmip-pcmdi.llnl.gov/cmip5/docs/CMIP5_output_metadata_requirements.pdf ... but obviously we ignore the stuff that is specific to the CMIP5 experiments); this approach might not be perfectly suitable for all data sets and exceptions are normal. However, we should intend to minimize the risk of errors in the synthesis-phase of the components/project where typically, unit conversion etc may causes trouble. Some basics requirements that must be fulfilled are e.g. to have
  • Global attributes
    • institution = "Max-Planck-Institut fuer Biogeochemie";
    • :institute_id = "MPI-BGC";
    • :data_id = "XYZ";
    • :contact = "Data Producer (dummy@xxx-jena.mpg.de)" ;
    • :history = "Output from original paper / Ulrich Weber rewrote data to comply with GEOCARBON requirements." ;
    • :references = "Cite your paper here" ;
    • :frequency = "mon" ;
    • :creation_date = "2010-04-21T21:05:23Z" ;
  • Ordering of dimensions
• Data should be in CMIP5 conformal units and using the corresponding long and short names; at http://cmip-pcmdi.llnl.gov/cmip5/output_req.html you find a spread sheet called "standard_output" where a wide range of variables is described. Otherwise please use some clean and non-confoundable namings of your variables.
• We could prepare an example files here at the MPI and send them to you on request
• The meta-information (ncdump -h) will be visible to everybody - but the actual data only to "General users" etc ....see the data policy agreement on this issue.
• Please name the files as PROJECT_VariableName_institute_id_VersionNr.nc

Uploaded files are made available on this Data Portal, if they confirm to the rules above. The submitter will then be made an associated member of the project and will be able to download files unrestrictedly.
