Processes and models gravity and magnetic potential field data using the Fatiando a Terra ecosystem.
Harmonica provides specialized capabilities for geoscientists and geophysicists to perform gravity and magnetic data processing directly within AI-assisted coding environments. It enables complex workflows including forward modeling with rectangular and spherical prisms, applying essential terrain and Bouguer corrections, and gridding irregular survey data via equivalent sources. Whether you are performing regional crustal studies or local mineral exploration, this skill streamlines the application of potential field theory and FFT-based filters like upward continuation and tilt angles.
