1 Van Allen Probes Data and Services at SPDF Bob McGuire Project Scientist, Space Physics Data Facility (SPDF) Heliophysics Science Division (Code 670) NASA Goddard Space Flight Center Presented to Van Allen Probes Data Session at GEM June 18, 2013 Page 1; SPDF & Van Allen Probes at GEM

2 SPDF s Support for the Van Allen Probes SPDF is a Heliophysics active Final Archive and a Center of Excellence for correlative science data and services By working jointly with the Van Allen Probes team Easy common access to data from all the experiments Framework for ready comparison of Van Allen Probes and other data Van Allen Probes science gains from other data Investigations centered on other data gains capabilities of Van Allen Probes Highest-value data is immediately in a long-term NASA archive SPDF support has included: Common Data Format s/w and ISTP/SPDF metadata standards Collaboration with PI teams to produce useful metadata for services Range of online access and services for Van Allen Probes data Resource for other services e.g. Autoplot and NASA Virtual Observatories Orbit displays and services (SSCWeb and 4D Orbit Viewer) Page 2; SPDF & Van Allen Probes at GEM

3 Accessing Data: Getting Started Go to Select CDAWeb Select CDAWeb Inside IDL Link to FTP/HTTP directories OR Go directly to Page 3; SPDF & Van Allen Probes at GEM

4 Select a Data View Van Allen Probes are in current and all space physics data Note links to overall Web Services and the Autoplot interface Page 4; SPDF & Van Allen Probes at GEM

5 Select Mission(s)/ Instrument(s) E.g. Van Allen Probes (RBSP) Option to select a more specific kind of data And to select data from other missions or ground sources And Submit Page 5; SPDF & Van Allen Probes at GEM

6 Select Dataset(s) of Interest: ECT Page 6; SPDF & Van Allen Probes at GEM

7 Select Dataset(s) of Interest: RBSPICE, EFW Page 7; SPDF & Van Allen Probes at GEM

8 Select Dataset(s) of Interest: EMFISIS Mag Page 8; SPDF & Van Allen Probes at GEM

9 Select Dataset(s) of Interest: EMFISIS Waves Page 9; SPDF & Van Allen Probes at GEM

10 CDAWeb Activities Set Time Range Many datasets are nearly current Activities Plots (inc. PS/PDF) Lists (Space-delimited) Tar/gzip options Downloads CreateCDF Link to Autoplot Common focus toward subsets / supersets in time and among variables Plot Options Page 10; SPDF & Van Allen Probes at GEM

11 Select and Submit Select variable(s) to plot/list etc. Can select from many datasets at once Simple checkboxes Dataset names reflect RBSP heritage SPDF has worked extensively on texts Submit Top or bottom Note Links by dataset Data Inventory & other links Page 11; SPDF & Van Allen Probes at GEM

12 Van Allen Probes and Ancillary Data in the March 17, 2013 Storm Event Probes A and B RBSPICE Ions and Electrons Solar wind drivers seen at ACE Page 12; SPDF & Van Allen Probes at GEM

13 Van Allen Probes and Ancillary Data in the March 17, 2013 Storm Event EMFISIS HFR Spectra EFW E-fields ECT MagEIS Electrons and Ions Also Note: Various s/c positions on 2013 March 17 at 1000UT - From 4D Orbit Viewer - Viewer supports pan/ zoom, rotate, play in time, display of footpoint tracks Easy to change from e.g. 3 days to 3 seconds plot resolution Page 13; SPDF & Van Allen Probes at GEM

14 Example Request Outputs for selected times, variables Merged in time but separate files for separate datasets Files are supplied native and as tar/ gzip s and as combined tarball Feature buttons for previous/next, zoom in/out (by 2) pan (by ½) Page 14; SPDF & Van Allen Probes at GEM

15 Fill My (IDL) Array with Data from CDAWeb 1) Load specific CDAWeb data into an IDL structure Invoke spdfgetdata 2) Use GUI to select/load/display data Invoke spdfcdawebchooser Page 15; SPDF & Van Allen Probes at GEM

16 Additional Tools and Utilities SKTEditor (design a compliant CDF) makecdf/idlmakecdf To help load data into a CDF Other tools (e.g. Autoplot) Leveraging the format and metadata standard and the metadata value added by SPDF through CDAWeb master CDFs CDF toolkit to manipulate CDFs Page 16; SPDF & Van Allen Probes at GEM

17 Files Online at SPDF Directory structure appears the same whether FTP or HTTP rbsp is one of many projects within the data directory Including older missions previously held by NSSDC Simple hierarchy Probes A/B L1/2/3 ECT/EFW/EMFISIS/ RBSPICE/RPS Products and dates Page 17; SPDF & Van Allen Probes at GEM

18 A Last Note: SPDF Usage and Acknowledgements ~24% of space physics 2012 papers in AGU journals acknowledged SPDF services and/ or data (which is a modest increase over similar acknowledgments in 2011/2010/2009) FY2014 PPBE Submit Project Number and Name Page 18; SPDF & Van Allen Probes at GEM
