MsTMIP Product Use and Co-Authorship Policy (EFFECTIVE 11/1/2012)


The MsTMIP experimental protocol, environmental driver data, and model simulation output are made freely available to the public and the scientific community. In order to ensure that MsTMIP researchers receive fair credit for their work and the opportunity to contribute as co-authors to MsTMIP-related publications, all users must contact the MsTMIP core and any relevant MsTMIP participants as early as practical in the project. This policy applies to users both internal and external to the MsTMIP team.


The MsTMIP environmental driver data package (Wei et al., 2013) and model simulation output (collectively termed “MsTMIP products”) are made freely available to the public and the scientific community (termed “MsTMIP users”) and are part of an extensive collaborative intercomparison effort (Huntzinger et al., 2013). However, we expect all users of MsTMIP products to ensure that the MsTMIP core team members (termed “MsTMIP core”) and modeling team participants (termed “MsTMIP participants”) receive fair credit for their work, and are offered co-authorship and the opportunity to contribute to the research uses of these products as appropriate. Thus, when using results from a MsTMIP participating model, please contact the modeling team PI (link) for additional information about other model team members that should be included as co-authors on manuscripts, presentations, etc. Users of MsTMIP data products should work with the model team PIs to ensure that: (1) the model team PIs and all appropriate model team members are included early on in discussions concerning analyses, manuscripts, co-authorship, etc. and (2) that each model’s structure, parameters, internal processes are accurately represented in the manuscript.

Accordingly, we ask that all MsTMIP users adhere to the following guidelines and procedures when using MsTMIP products:

  1. MsTMIP products are freely available for exploratory analysis. At such a time as a journal publication or conference presentation is planned using MsTMIP products, the MsTMIP users should inform the MsTMIP core (link to email) and any MsTMIP participants responsible for specific model results included in the analysis of the nature and aims of the research project and the intended use of the MsTMIP products. This will take the form of an abstract of intent (see example below), to be emailed to the MsTMIP core and relevant MsTMIP participants. Contact details are also given on the MsTMIP project webpage. When you contact us, please allow 2 weeks for a response, although in most cases we will make every effort to respond more quickly.
  2. The abstract of intent will ensure that the MsTMIP core and MsTMIP participants have adequate fore−knowledge of the proposed research and thus the opportunity to contribute, as appropriate, to the use of MsTMIP products in the research project.
  3. If (a) the MsTMIP core, MsTMIP participants, and/or members of the MsTMIP participants group make a significant intellectual contribution to the research, and/or (b) MsTMIP products are essential to the work, and/or (c) an important result or conclusion depends on the MsTMIP products, co−authorship should be offered. This should be discussed at an early stage in the work (refer to additional co-authorship guidance for group members below).
  4. In addition to an abstract of intent, manuscripts using MsTMIP products should be sent to the MsTMIP core and any relevant MsTMIP participants for review well before they are submitted for publication, so that modelers and the MsTMIP core have adequate time to provide input on the quality and limitations of MsTMIP products. It is our preference that we be contacted as early as practical in the manuscript preparation process, but request that a draft be shared with us a minimum of four weeks prior to submission. This will ensure an opportunity for meaningful input and will make it possible to accommodate any prior commitments by the MsTMIP core and/or MsTMIP participants that may make a quicker review impractical.
  5. All products (e.g. manuscripts, reports, abstracts, presentations) relying on MsTMIP products should include an acknowledgment, regardless of whether the MsTMIP core and/or MsTMIP participants are co-authors on the work. Specific wording for acknowledgment of the MsTMIP activity is provided below and individual models is provided below.

Additional guidance for co-authorship expectations for model team members (in addition to model team PIs):

In addition to the model team PI, the following contribution warrants co-authorship for others as members of the PI's modeling team group:

  • The student/postdoc/staff-person served as the intellectual lead on the work; or
  • The student/postdoc/staff-person altered the model in order to make the MsTMIP runs feasible.

For others in the group, the following contribution warrants acknowledgement, but not necessarily co-authorship:

  • The student/postdoc/staff-person ran the model according to instructions obtained from the PI, bud did not make significant change to the model in order to make the MsTMIP runs feasible.

For the MsTMIP project:

"Funding for the Multi-scale synthesis and Terrestrial Model Intercomparison Project (MsTMIP; activity was provided through NASA ROSES Grant #NNX10AG01A. Data management support for preparing, documenting, and distributing model driver and output data was performed by the Modeling and Synthesis Thematic Data Center at Oak Ridge National Laboratory (ORNL;, with funding thorugh NASA ROSES Grant #NNH10AN681. Finalized MsTMIP data products are archived at the ORNL DAAC ( This is MsTMIP contribution #XX."

Please note: contact the MsTMIP core team to determine the MsTMIP contribution # (above). For individual model acknowledgements, please use the wording provided here and in consultation with individual model team PIs.

MsTMIP is funded by NASA's Terrestrial Ecology Program (Phase 1 funded by NASA Grant NNX11AO08A and Phase II by NASA Grant NNX14AI54G). During Phase 1, data management for MsMTIP was conducted by MAST-DC, with funding from NASA's Terrestrial Ecology Program (NASA Grant NNH10AN68I). This is a contribution of the North American Carbon Program.
