MACPEX Science - Data Archive

MACPEX Data Archive

The Mid-latitude Airborne Cirrus Properties Experiment (MACPEX) Science Team (ST) is composed of the participating instrument and theory team Principal Investigators (PIs) and Co-Investigators, Project Scientists, Program Managers and Project Managers, and satellite instrument investigators.

The rapid exchange of data assists in-field collaborations, identifies instrument problems via inter-comparisons, and helps flight planning by identifying new and interesting geophysical problems, and determining whether or not flight objectives are realized. Therefore, a real-time data product is required to be transmitted from all MACPEX instruments. The display and archiving of this real time product will be determined via discussions with the MACPEX project scientists. The data acquired during the field deployment will be archived within 24 hours after the aircraft lands and will constitute a preliminary archive. Some exceptions for unique operation may be granted on a case-by-case basis by the project management. H2O intercomparison measurements will be announced on a per flight basis and data instructions will be announced at a later date.

Updated/re-calibrated versions of the archived data sets are due within six months after the field deployment, and the MACPEX data sets will be released to the public 12 months after the deployment. Throughout this process the members of the ST will have free access to and use of those archived data sets. Prior to the public release of each data set, it will not be provided to persons outside of the ST without the expressed approval of that data set's PI.

Likewise, the MACPEX ST members will have access to related satellite data products from the NASA DAACs at GSFC and LaRC, or other mechanisms defined by the participating satellite instrument teams for distributing preliminary data products. Since MACPEX data products will be used to validate the satellite measurements, early versions of the satellite data products are expected to be preliminary and improved upon in subsequent releases.

Publication schedules and ST meetings will be announced. Manuscripts submitted for publication in peer-reviewed journals should involve all ST members involved in the preparation of the measurements and their interpretation in the manuscript. In particular, ST members responsible for generating a measurement or a data product must be offered the right of co-authorship. This right should be exercised only if the contribution is essential. Presentations of unpublished manuscripts in public meetings are subject to approval by the co-authors.

The primary archive for MACPEX is a new version of the ESPO Archive, available at http://espoarchive.nasa.gov/archive/browse/macpex. Help pages are available describing the archive and how to use it, and participant-only details about the archive are also posted online. The standard data format for MACPEX is the ICARTT format. Additionally, some instrument groups may use external archives for their preliminary and final data sets, which are also subject to the access and use terms of this protocol.
