Scientific Resource Access System R. A. DALEY ET AL. Scientifi c Resource Access System: A Concept for Getting “Living With a Star” Information to Do Science Rose A. Daley, Elisabeth A. Immer, Brand I. Fortner, and Michele B. Weiss Answering complex science questions often means that a scientist must fi nd and use a variety of scientifi c resources, including static and dynamically generated data in different formats, complex data assimilation models, and conversion and analysis tools. Although the Internet has led to an explosion of accessible scientifi c resources, it has also created a Babel of incompatible formats, data descriptions, and access methods from many disparate sources. An evolving prototype called the Scientifi c Resource Access System (SRAS) is being developed that uses metadata and commonly understood scientifi c concepts to provide easier discovery and access to these necessarily heterogeneous resources for “doing science.” This concept simplifi es the integration of distributed scientifi c resources within a single system and enables the interconnection of complex data systems. An additional goal of SRAS is to eliminate the need for specialized integration software and the need to force data standardization on participating resources. Both are infeasible in Internet- based scientifi c data environments, where the additional effort and expense required for such solutions would effectively eliminate a substantial quantity of important scientifi c resources. Instead, the SRAS uses existing protocols and formats along with robust meta- data to simplify integration.

Therefore, to gather and share static and dynamically generated LWS includes a wide variety of scientifi c disciplines (e.g., data, metadata, documentation, and model results, as solar, space, ionospheric, and magnetospheric physics), a well as associated analysis tools and services, without 22 JOHNS HOPKINS APL TECHNICAL DIGEST, VOLUME 26, NUMBER 1 (2005) SCIENTIFIC RESOURCE ACCESS SYSTEM The heart of the SRAS is a con- ceptual model of commonly under- stood scientifi c concepts, augment- ed by robust metadata supplied by the creator of the resource to facili- tate resource discovery and access.

Corresponding author: Janet Luhmann ([email protected]) Key Points: Observer shock connectivity explains the SEP observations during the July and September 2017 events. The July and September 2017 solar and SEP events had similar characteristics due to similar source region and eruptions. The July and September 2017 events seemed to arise in conjunction with the appearance of a pseudostreamer, a possible alternate ICME source.

Abstract As solar activity steadily declined toward the cycle 24 minimum in the early months of 2017, the expectation for major Solar Energetic Particle (SEP) events diminished with the sunspot number. It was thus surprising (though not unprecedented) when a new, potentially significant active region rotated around the East limb in early July that by mid-month was producing a series of coronal eruptions, reaching a crescendo around July 23. This series, apparently associated with the birth of a growing pseudostreamer, produced the largest SEP event(s) seen since the solar maximum years.

  • The Van Allen Probes' Contribution to the Space Weather System
    L. J. Zanetti et al. The Van Allen Probes’ Contribution to the Space Weather System Lawrence J. Zanetti, Ramona L. Kessel, Barry H. Mauk, Aleksandr Y. Ukhorskiy, Nicola J. Fox, Robin J. Barnes, Michele Weiss, Thomas S. Sotirelis, and NourEddine Raouafi ABSTRACT The Van Allen Probes mission, formerly the Radiation Belt Storm Probes mission, was renamed soon after launch to honor the late James Van Allen, who discovered Earth’s radiation belts at the beginning of the space age. While most of the science data are telemetered to the ground using a store-and-then-dump schedule, some of the space weather data are broadcast continu- ously when the Probes are not sending down the science data (approximately 90% of the time). This space weather data set is captured by contributed ground stations around the world (pres- ently Korea Astronomy and Space Science Institute and the Institute of Atmospheric Physics, Czech Republic), automatically sent to the ground facility at the Johns Hopkins University Applied Phys- ics Laboratory, converted to scientific units, and published online in the form of digital data and plots—all within less than 15 minutes from the time that the data are accumulated onboard the Probes. The real-time Van Allen Probes space weather information is publicly accessible via the Van Allen Probes Gateway web interface. INTRODUCTION The overarching goal of the study of space weather ing radiation, were the impetus for implementing a space is to understand and address the issues caused by solar weather broadcast capability on NASA’s Van Allen disturbances and the effects of those issues on humans Probes’ twin pair of satellites, which were launched in and technological systems.
