What is AMGeO?
AMGeO is a collaborative data science platform for the geospace science community for bringing together a diverse set of heterogeneous geospace observations from NSF-funded facility programs and individual community users to obtain complete maps of high-latitude ionospheric electrodynamics for scientific discovery and space weather research. The platform is made of the AMGeO open-source software and web application services that facilitate the data acquisition and pre-processing steps that are otherwise prohibitively labor-intensive. It is developed at the University of Colorado Boulder by the AMGeO Team, with support from the NSF Earth Cube program.
The AMGeO open-source software is designed to streamline data access, collection, preprocessing, and quality control steps with data assimilation analysis steps to support accessible, reproducible and transparent data science practices in the geospace science community. AMGeO helps accelerate data science processes by transforming raw data into discovery enabling forms. AMGeO implements data assimilation analysis steps expanded, as summarized in Matsuo (ISSI Scientific Report Series, 2020), from the Assimilative Mapping of Ionospheric Electrodynamics (AMIE) procedure originally developed by Richmond and Kamide (JGR, 1988). AMGeO's web application services facilitate the data acquisition of plasma drift data distributed from the SuperDARN Website, ground-based magnetometer data distributed from the SuperMAG Website, and space-based magnetometer data distributed from the AMPERE Website in the form expected by the AMGeO software.
Frequently Asked Questions
Q1. What are types of data AMGeO is capable of ingesting?
Currently AMGeO is capable of ingesting SuperDARN and SuperMAG data as well as Iridium magnetic fields provided by the AMPERE program. In future AMGeO software releases, AMGeO will be able to use other types of data, such as particle precipitation and FUV image data from DMSP satellites.
Q2. How to find SuperDARN data availability.
The AMGeO software is designed to use the SuperDARN grid2 data product. The grid2 data availability can be found on the SuperDARN Data Inventory Site.
Q3. How to find SuperMAG data availability.
The AMGeO software is designed to use the SuperMAG Baseline Subtracted data product. The SuperMAG data availability can be found on the SuperMAG Magnetometer Data Site.
Q4. How is auroral conductivity determined in AMGeO?
Currently AMGeO uses the Ovation Prime model by Newell et al. (JGR, 2009) and empirical relationships of Robinson et al. (JGR, 1987).

AMGeO is supported by the NSF EarthCube grants ICER 1928403 to the University of Colorado Boulder, ICER 1928327 to the Virginia Tech, and ICER 1928358 to the Johns Hopkins University Applied Physics Laboratory. We are grateful for the community data providers (NASA SPDF, SuperMAG, SuperDARN, and AMPERE) for providing data for the community such that they can be used in AMGeO. Special thanks to SuperMAG, SuperDARN, and AMPERE for working with the AMGeO Team to establish API access to their data services.
