Data providers and the respective responsible scientists are ETH (Richner), U Basel (Vogt), MeteoSwiss (Rotach, Ruffieux), Obs. Neuchâtel (Mitev), IU (Grimmond), UBC (Oke), U Singapore (Roth), U Western Ontario (Voogt), U Tasmania (Nunez), U Padova (Pitacco), U Freiburg (Mayer), TU Dresden (Bernhofer), Risø National Laboratory (Gryning), University of Hamburg (Schatzmann), National Institute for Meteorology and Hydrology, Sofia (Batchvarova) .

As a core group of the original proposal, the modeling group of EPFL (Clappier) has the same status as a data provider. The same applies for Ohio State University (Arnfield) through the collaboration with UBC. Other modeling groups may apply for this status.

II:

The data providers share the data set gathered as a whole. Each of the data providers keeps the others informed on the results of his research.

III:

The entire BUBBLE data set can be made available to external groups if all the data providers agree. The 'applicant' gets the data for a clearly specified project. Disagreement can be claimed if a data provider himself/herself wants to perform the research as proposed by the 'applicant'. In particular, the research interests of the involved PhD students (i.e., those from the data provider groups) have to be given highest priority.

IV:

If the (external) 'applicant' works together with one or more of the data providers, the (possible) objections of the other data providers have to be particularly well founded.

V:

Giving away data does not qualify for co-authorship in publications, which result from the research of the 'applicant', unless a data provider has actively contributed to the establishment of the achieved results. However, it qualifies for 'acknowledgements'.

VI:

Subsets of a data provider’s own data can be given away by one of the data providers for highly specific research questions [As an example: if the wind profiler group would want to give away some of the raw data to another group, who would want to test a new algorithm to retrieve turbulence statistics]. In such a case the other data providers will be informed but not consulted.
