EarthCube: Assimilative Mapping of Geospace Observations

Diagram of high-latitude ionospheric currents in which the earth has field aligned currents and pedersen currents circulating across its surface
The most dynamic electromagnetic energy and momentum exchange processes between the upper atmosphere and the magnetosphere take place in the polar ionosphere as evidenced by the aurora. Accurate specification of the constantly changing conditions of high-latitude ionospheric electrodynamics has been of paramount interest to the geospace science community.Inspired by recent advancements in geospace observing capabilities and the opportunities of Big Data, the proposal aims (1) to develop and deploy an open-source Python software and associated web-applications for that are interoperable with established geospace community data resources and standards, and (2) to create fully reproduceable, validated reanalysis data products that can be accessed from established data repositories to maximize the scientific return on the NSF, DOD and NASA program investments.

The project aims to:

  1. Empower individual researchers by providing the latest geospace assimilative mapping tool as an open-source software called AMGeO. Its auxiliary web application service will automate data collection and AMGeO itself will handle pre-processing and quality control steps to minimize technical and implementation barriers thus mitigating prior hurdles for users of the current AMIE procedure.
  2. Maximize the scientific return on the NSF, DOD, and NASA investments in the AMPERE, SuperDARN, SuperMAG, DMSP and TIMED programs as well as in the innovative citizen science initiative Aurorasaurus.
  3. Provide a much deeper understanding of geospace systems through the systematic analysis of multiple types of space-based and ground-based observations into the unified data science framework offered by AMGeO. 
  4. Catalyze a cultural change within the geospace community by promoting a new open-source and open-data collaborative paradigm, gradually but fundamentally transforming the way the geospace community uses these data with transferable Big Data technical skills thereby enticing younger investigators to go into the geospace sciences
