The Gravitational Accelerations Inverter and Analyzer (GAIA) analyzes accelerations caused by gravity, such as those recorded by GRACE. GAIA inverts these accelerations using a mascon technique to determine the mass distribution that most closely matches the acceleration data.

GAIA creates a timestamped output folder filled with data and a source code snapshot. Output data files are provided in plain text and NetCDF formats.

Output map data are turned into PNG maps using a script which runs GMT and ImageMagick. This script can be modified and re-run, changing the projection or zooming in on a specific part of the world, which will automatically recalculate the "data range" blurb using only data inside the new zoomed region.

Output time series data are analyzed by an R script which calculates statistical significance, but interpret those results with caution. For example: do the residuals look random? Does the default autocorrelation model minimize the AIC or BIC? Etc.
