•SECCHI (PI Russ Howard, NRL)- Remote Sensing Package that will track Coronal Mass Ejections (CMEs) from the Sun to the Earth.
• Two White Light Coronagraphs (COR1,COR2)- COR1 explores 1.4 – 4 Rsun. COR2 explores 2 – 15 Rsun• Extreme Ultra Violet Imager (EUVI)- Observes chromosphere and inner corona• Heliospheric Imager (HI1, HI2)- Observes Coronal Mass Ejections from the Sun to the Earth (12 – 300 Rsun)
•IMPACT (PI Janet Luhmann, UCB)- will sample the 3-D distribution of solar wind plasma electrons, the characteristics of the energetic particle ions and electrons, and the local magnetic field.
•Solar Wind Experiment (SWEA)-Measures ~0-3 keV electrons with wide angle coverage•Suprathermal Electron Telescope (STE)-Measures electrons from 2-100 keV with wide angle coverage•Magnetometer Experiment (MAG)-Measures the vector magnetic field at 65,536 nT and 500 nT ranges•Solar Energetic Particle Experiment (SEP) Suite
– Measures electrons from 0.02-6 MeV– Measures protons from 0.02 – 100 MeV– Measures helium ions from 0.03 – 100 MeV/nucleon– Measures heavier ions form 0.03 – 40 MeV/nucleon
•PLASTIC (PI Toni Galvin, UNH) - will provide the plasma characteristics of protons, alpha particles, and heavy ion. Provide composition measurements of heavy ions and characterizes the CME plasma
•SWAVES (PI Jean-Louis Bougeret, Paris Obs.)- in-situ as well as remote sensing instrument. Tracks CME Driven Shocks from the Corona to the Earth.

IMPACT Data Products
• Beacon– Produced at SSC (GSFC)– Uses NOAA antenna partners for 24/7 space weather monitoring
• L1– Produced at UCB– Highest time resolution data in physical units of all measured quantities– Available in variety of formats (CDF, ASCII, FITS, …)– Reside natively in ISTP-compliant CDF’s
• L2– Produced at UCLA– Key parameter (1-minute cadence) data in physical units– Includes PLASTIC and SWAVES– Available in ASCII
• L3– Produced at UCLA– Higher level products such as event lists– ASCII

Beacon Data Processing Software Update
• IMPACT delivered first version of Beacon processing software to SSC in November
• Outstanding issues:– Need calibration data to finish conversion to physical
units (SWEA and STE)– Not all status codes have been fully defined (SEP)– Still need to check-out MAG code– All instruments: Need to convert from instrument
coordinates to STEREO HGRTN coordinates
![Page 10: IMPACT Data Plans May 2006 Peter Schroeder UC-Berkeley peters@ssl.berkeley.edu.](https://reader036.fdocuments.net/reader036/viewer/2022070412/5697bf771a28abf838c817c1/html5/thumbnails/10.jpg)
L1 Data Processing Software Update
• LET, SIT, SEPT, MAG, SWEA and STE have delivered software but all require further testing (and calibrations)
• Still need HET software (delivery expected very soon)
• Possibility of sharing pre-validated data with PLASTIC and S/WAVES
• Produced preliminary L1 science products during recent Mission Simulation
![Page 11: IMPACT Data Plans May 2006 Peter Schroeder UC-Berkeley peters@ssl.berkeley.edu.](https://reader036.fdocuments.net/reader036/viewer/2022070412/5697bf771a28abf838c817c1/html5/thumbnails/11.jpg)
L2 Data Processing Software Update
• Need to finalize quantities to include in L2
• First cut quantities = Beacon quantities
• Possibility of including derived quantities
• Need to continue working with PLASTIC and S/WAVES
![Page 12: IMPACT Data Plans May 2006 Peter Schroeder UC-Berkeley peters@ssl.berkeley.edu.](https://reader036.fdocuments.net/reader036/viewer/2022070412/5697bf771a28abf838c817c1/html5/thumbnails/12.jpg)
Building from CDAWeb
![Page 13: IMPACT Data Plans May 2006 Peter Schroeder UC-Berkeley peters@ssl.berkeley.edu.](https://reader036.fdocuments.net/reader036/viewer/2022070412/5697bf771a28abf838c817c1/html5/thumbnails/13.jpg)
CDAWeb+
• Primary access point for IMPACT Level 1 Data• Ability to save previous plot layouts• More flexibility with plot titles, axes, linestyles• Export underlying CDF’s to many other formats
(ASCII, FITS, CDFML (XML))• Tight integration with L1 spacecraft (ACE, WIND,
etc.)• Other possible funcionalities? Do we want to include
some derived quantities? Other plotting abilities not available in CDAWeb that would be appropriate for multi-spacecraft (time delays)? What about images? Mapping to solar images/movies?
![Page 14: IMPACT Data Plans May 2006 Peter Schroeder UC-Berkeley peters@ssl.berkeley.edu.](https://reader036.fdocuments.net/reader036/viewer/2022070412/5697bf771a28abf838c817c1/html5/thumbnails/14.jpg)
SOAP Interface
• Simple Object Access Protocol is a web services messaging standard used increasingly by industry
• Allows local/custom applications to query and access data over the web
• Will conform to emerging VHO standard (which will interface with the VSO and other VxO’s)
• Current model is the ACE Science Center using a modified version of the SPASE dictionary to define queries, but SPASE needs expanding to fit needs of particle data
![Page 15: IMPACT Data Plans May 2006 Peter Schroeder UC-Berkeley peters@ssl.berkeley.edu.](https://reader036.fdocuments.net/reader036/viewer/2022070412/5697bf771a28abf838c817c1/html5/thumbnails/15.jpg)
Berkeley Static Data Plots
• In addition to CDAWeb-like browser, Berkeley intends to make static plots at different time intervals (daily, 3- and/or 7-day, and Carrington Rotation)
• Primarily intended for internal diagnostic use but will provide interface for the larger community
• HELIOS/IMP-8/ISEE-3 browser as proxies for STEREO/ACE at: http://sprg.ssl.berkeley.edu/impact/data_browser.html
• Again, question of how best to utilize/visualize multi-spacecraft data

Beacon Data Browser
• IMPACT responsible for “in situ-only” Beacon data browser (SSC will create an “integrated” browser as well)
• How best to display these data? Probably need input from NOAA and other end users.
• Do we make static or dynamic plots? If dynamic, should there be a standard default plot(s)? If so, what should it look like?
• Should we try to include ACE NRT data?
