Mission-Level Science and Data Operations (1/3) 2.2.1 Coordination of Science/data Activities During Phase C/D, the RBSP Mission, through discussions of the Science Working Group (SWG), will develop methods of collaboration with the broader heliophysics community. This will involve the development of “Rules of the Road” and govern how RBSP instrument data is used. To include “Rules of the Road” To include a description of the science data portal, the interaction with the VxO’s and information on how the project will support the broader heliophysics goals as laid out in the Heliophysics Science Data Management Policy SWG PDMP Discussion
Mission-Level Science and Data Operations (2/3) 2.2.2 COORDINATION OF SCIENCE/DATA ACTIVITIES BETWEEN TEAMS During Phase C/D, the RBSP Mission, through discussions of the Science Working Group (SWG), will develop methods of collaboration between the instrument teams. Data sharing plans from each team SWG PDMP Discussion
Mission-Level Science and Data Operations (3/3) 2.2.3 COORDINATION OF SCIENCE/DATA ACTIVITIES WITH OTHER ASSETS AND MISSIONS The RBSP Mission will fully support the broader goals of the Heliophysical data environment by providing full and open access to RBSP higher level data products. During Phase C/D, the SWG will discuss coordination, cross calibration, and collaboration with other assets and missions and develop a comprehensive framework for sharing data. The instrument teams will create meta-data products to help integrate RBSP data into the appropriate NASA Virtual Observatories. Are any teams planning to do cross-calibration with instruments aboard other missions? If so, do you require support at a mission level? If the answer to this is no, then this section may be combined with 2.2.1 so that the other assets are a subset of the broader HP community SWG PDMP Discussion
Other TBDs in the document • Section 4 (Data products) • intro material including definition of data levels (and latency requirements) and table of mission products • Data volumes • RBSPICE to identify tools to be provided (or delete phrase "tools will be identified during phase CD") (4.3.4) • Section 5 (Data Archive) • intro including reference to mission archive plan • Section 6 (Data availability) • Intro with information about the VxOs and resident archive model • EFW data catalog in 6.3.3 SWG PDMP Discussion
RBSP Draft Rules of the Road for Data Usage • The PI shall make all Level 2 - 4 data products available to the public, as stated in the RBSP Science Data Management Plan. • Users should consult with the PI to discuss the appropriate use of instrument data or model results and to ensure that the Users are accessing the most recent available versions of the data and analysis routines. VxOs should facilitate this, serving as the contact point between PI and users in most cases. • Users should heed the caveats of investigators to the interpretation and limitations of data or model results. Investigators supplying data or models may insist that such caveats be published, even if co-authorship is declined. Data and model version numbers should also be specified. • Browse products are not intended for science analysis or publication and should not be used for those purposes without consent of the PI. • Users should acknowledge the sources of data used in all publications, presentations, and reports. " We acknowledge the NASA Radiation Belt Storm Probes Mission and [PI name] for use of data.”(list of PIs) • Users are requested to provide the PI a copy of each manuscript that uses the PI’s data upon submission of that manuscript for consideration of publication. On publication the citation should be transmitted to the PI and any other providers of data. SWG PDMP Discussion
RBSP Mission Products by Level ? ? ? SWG PDMP Discussion
NASA Data Levels • (Defined in the Earth Science Reference Handbook: http://eospso.gsfc.nasa.gov/ftp_docs/2006ReferenceHandbook.pdf) Level 0 • Reconstructed, unprocessed instrument/payload data at full resolution; any and all communications artifacts, e.g., synchronization frames, communications headers, duplicate data removed. In most cases these data are provided by EDOS to a DAAC as Production Data Sets for processing to the SDPs in the DAAC or by the SIPSs to produce the higher-level products. Level 1A • Reconstructed, unprocessed instrument data at full resolution, time-referenced, and annotated with ancillary information, including radiometric and geometric calibration coefficients and geo-referencing parameters, e.g., platform ephemeris, computed and appended but not applied to the Level 0 data. Level 1B • Level 1A data that have been processed to sensor units (not all instruments have Level1B data products). Level 2 • Derived geophysical variables at the same resolution and location as Level 1 source data. Level 3 • Variables mapped on uniform space-time grids, usually with some completeness and consistency. Level 4 • Model output or results from analyses of lower level data, e.g., variables derived from multiple measurements. SWG PDMP Discussion
Suggested RBSP Data Levels Level 0 • Reconstructed, unprocessed instrument/payload data at full resolution; any and all communications artifacts, e.g., synchronization frames, communications headers, duplicate data removed. Level 1A • Reconstructed, unprocessed instrument data at full resolution, time-referenced, and annotated with ancillary information, including radiometric and geometric calibration coefficients and geo-referencing parameters, e.g., platform ephemeris, computed and appended but not applied to the Level 0 data (uncalibrated) Level 1B • Level 1A data that have been irreversibly transformed to sensor units (e.g., resampled, remapped, calibrated) Level 2 • Derived geophysical variables at the same resolution and location as the Level 1 source data. Level 3 • Variables mapped on uniform space-time grids, usually with some completeness and consistency. Level 4 • Model output or results from analyses of lower level data, e.g., variables derived from multiple measurements. SWG PDMP Discussion

RBSP Team Data Sharing Plans SWG PDMP Discussion
PSBR data sharing plan Which products do you intend to make available for use by other teams in their data analysis? We intend to provide our L0-L4 data and supporting information as specified in the PSBR/RPS PDMP. We have an informal agreement with ECT to share such data as may improve data reduction. The need for such data, and its precise form, cannot be defined until the flight models are subjected to beams. When will these products be available? L0-L4 data will be available as specified in the PSBR/RPS PDMP. Schedule for data provided to ECT cannot be defined at this time. SWG PDMP Discussion 16
PSBR data sharing plan What products do you need from other teams? We will need calibrated MAG data. We will also need the L*/K values provided by the ECT SOC if we are to provide our data in coordinates derived from a dynamic Tsyganenko-Sitnov model. When do you need these products to be available? We will re-run our analysis algorithms each time a new version of the MAG or L*/K data is made available. When MAG data is not available, we will use a static model (OPQ) . Therefore, we have no specific timeline requirement from MAG. As for L*/K, we do not have internal use for dynamic models, and we have the capability to create static model coordinates ourselves. We will just create the products that require L*/K in a dynamic model as those coordinates become available from ECT. SWG PDMP Discussion 17
PSBR data sharing plan What other products do you need from outside RBSP – Indices/IMF/supporting data. GCR measurements (for on-orbit calibration) Solor proton event measurements (supports science study, but we could do it with RBSP measurements only). What software, tools and models (if any) do you intend to make available for use by other teams in their data analysis? None have been requested. However, we do contribute to the IRBEM library, which is an open-source, shared resource that may be used by other teams (ECT?). When will these be available? Upon request. What software, tools and models would you like to be available for use? The scope of this question is unclear. We are not expecting any software from any of the other instrument teams. From NASA we are expecting SPICE, which is already available on the Web. We are expecting to acquire the GSE-OS SOC template from APL or GSE-OS Inc. SWG PDMP Discussion 18
