Perdigão Data Policy

Updated 26 May 2017

The Perdigão Data Policy is an informal agreement among the participating science teams to work together before, during, and after the field deployment to maximize sharing and access to the the rich data legacy from this project.

The basis for the Perdigão Data Policy is the World Meteorological Organization (WMO) policy, practice, and guidelines for the exchange of meteorological, hydrological, and related data and products, as embodied in Resolution 40 of the Twelfth WMO Congress 1995 (CG-XII), and Resolution 25 of the Thirteenth WMO Congress 1999 (CG-XIII); that is, free, timely, and unrestricted exchange of essential data and products to the maximum extent possible. The purpose of the policy is to simply document what the PI teams have agreed to with regard to the submission, access, sharing and publication of Perdigão data.

The purpose of the policy is to simply document what the PI teams have agreed to with regard to the submission, access, sharing and publication of Perdigão data. It is meant to reinforce the data management approach being taken by the project. The complete Perdigão Data Policy is outlined below.

Perdigão Data Management Policy

It is appropriate that any policy for release and dissemination of Perdigão data should be consistent and in compliance with international standards and agreements including the World Meteorological Organization (WMO) policy, practice and guidelines for the exchange of meteorological, hydrological, and related data and products, as embodied in Resolution 40 of the Twelfth WMO Congress 1995 (CG-XII), and Resolution 25 of the Thirteenth WMO Congress 1999 (CG-XIII); that is, free, timely, and unrestricted exchange of essential data and products to the maximum extent possible.

In general, users will have free and open access to all the Perdigão data, subject to procedures to be put into place at the Perdigão Data Archive Center. The following is a summary of the Perdigão Data Management Policy by which all Perdigão participants, data collectors, and data users shall be requested to abide.

Prompt Submission of Data to the Perdigão Project Archive

All investigators participating in the Perdigão experiment agree to promptly submit their quality-controlled data to the appropriate Project Archive to facilitate intercomparison of results, quality control checks and inter-calibrations, as well as an integrated interpretation of the combined data set.

Reasonable Time for Data Availability

It is recognized that some special datasets, which include the tower data, Doppler wind LIDAR data, and Perdigão data, may not be entirely available until over 12 months following the end of the field collection on 15 June 2017. However, it is anticipated that the highest priority cases will be processed first and be available within one year of the completion of the field program. Therefore, an initial data analysis period is defined as 12 months following the end of the field collection. During this 12-month period, the Perdigão investigators shall have exclusive access to the data. This initial analysis period is set to accommodate the amount of processing required for all data products, to provide an opportunity to quality control the combined data set, and to provide the investigators ample time to publish their results.

Sharing of Special (Research) Datasets

During the initial data analysis period, the investigator(s) who collected the special data sets (from research observing facilities) must be notified first of any intent to use the data. In particular, this applies if data are to be provided to other parties via journal articles, presentations, and research proposals. It is expected that for any use of the Perdigão data investigators responsible for acquisition of data will be invited to become collaborators and co-authors on any projects, publications and presentations. If the contribution of the data product is significant to the publication, the Perdigão investigator responsible for generating a measurement or a data product should be offered the right of co-authorship or collaboration at the discretion of the investigator who collected the data. Any use of the data should include an acknowledgment (i.e., citation). In all circumstances, the Perdigão investigator or data source responsible for acquisition of data must be acknowledged appropriately.

Twelve Month Project Data Sharing Limited Access

During the first 12 months following the end of the field campaign, all Perdigão data will be accessible only to Perdigão investigators (password-protected) to facilitate inter-comparison, quality control checks and inter-calibrations, as well as an integrated interpretation of the combined data set.

No public release of the data (sharing with non-Perdigão colleagues, conference presentations, publications, commercial and media use, etc.) is allowed without the permission of the Perdigão PIs who are responsible for collecting the data.

Public Access

Following the end of the initial data analysis period, all data shall be considered in the public domain. A data set within the Perdigão archive can be opened to the public domain earlier at the discretion of the data provider for this particular data set. The Perdigão Data Center will coordinate their data management activities including developing consistent metadata generation, curation, and interoperability with other data centers.

Acknowledgement and Citation

The authorship decision for publications resulting from using Perdigão data should follow the ethics rules of the journals and professional organizations (e.g., EGU, AMS, AGU). Perdigão investigators responsible for field data collection are encouraged to make contributions to data analysis and writing of manuscripts, in addition to providing the data, to be co-authors of publications using Perdigão data. The following acknowledgements are suggested to be included in all publications using Perdigão data:

The xxxx data were collected as part of the Perdigão experiment, which was sponsored by (Agency Sponsor, NSF, etc.). The involvement of the NSF-sponsored National Center for Atmospheric Research (NCAR) Earth Observing Laboratory (EOL) is acknowledged (for ISFS, ISS data) or other University.

 

[The acquisition of the xxx data was carried out by YYYY (Facility or individual PI) under the support by wwww (funding agency) (if YYYY is not a co-author)]. The data are archived at the Perdigão Data Archive Center maintained by DTU, EOL, or UPORTO.]

When using data from the three DLR lidars, DLR’s microwave radiometer or DLR’s microphones, the following acknowledgement should be applied:

The [LIDAR, MWR, microphone] data from DLR were collected as part of the Perdigão experiment via the Projects “LIPS” and “DFWind Phase 1”, both funded by the German Federal Ministry of Economic Affairs and Energy on the basis of a resolution of the German Bundestag under Contract Numbers 0325518 and 0325936A, respectively.
