ICE-L DATA POLICY
(Reference only; Final ICE-L Policy TBD)

All investigators participating in ICE-L agree to promptly submit their quality controlled data to the ICE-L Data Archive Center. A submission deadline of 30-Sep-2008 is recommended.

During the initial data analysis period, defined as a one-year period following the agreed submission deadline to the archive, ICE-L PIs will have exclusive access to this data. This initial analysis period is designed to provide an opportunity to quality control the aggregate data set as well as to provide the investigators ample time to publish their results.

All data will be considered public domain one year after the agreed submission deadline to the ICE-L archive (i.e., on 1 October 2009 and thereafter). A data set within the archive can be opened to the public domain earlier at the discretion of the data provider for this particular data set.

All data shall be promptly provided to other ICE-L investigators upon request. All ICE-L investigators will have equal access to all data. A list of ICE-L investigators will be maintained by the ICE-L Project Office and will include the Principle Investigators (PIs) directly participating in the field experiment as well as collaborating scientists who have provided guidance in the planning and analysis of ICE-L data.

During the initial data analysis period, the investigator(s) who collected the data must be notified first of the intent to use the data, in particular if data are to be provided to a third party (journal articles, presentations, research proposals, other investigators). It is strongly encouraged that PIs responsible for acquisition of data 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 PIs responsible for generating a measurement or a data product should be offered the right of co-authorship. Any use of the data should include an acknowledgment (i.e., citation). In all circumstances, the PIs responsible for acquisition of data should be acknowledged appropriately.

The following acknowledgement is proposed for consideraton: The xxxx data was collected as part of the Ice in Clouds Experiment -- Layer Clouds (ICE-L). The primary sponsor of ICE-L is the US National Science Foundation (NSF). The involvement of the NSF-sponsored Lower Atmospheric Observing Facilities from the University of Wyoming and those managed and operated by the National Center for Atmospheric Research (NCAR) Earth Observing Laboratory (EOL) is acknowledged. The acquisition of the xxx data was carried out by Dr. Yyyyy using the zzzz instrument and was funded by wwww (if pertinent). The data were downloaded from the ICE-L Data Archive, which is maintained by NCAR EOL.
