Plume Tracer: Interactive Mapping of Atmospheric Plumes via GPU-based Volumetric Ray Casting

Completed Technology Project

Project Introduction

Real-time quantification of volcanic gaseous and particulate releases from analysis of satellite-based Thermal Infrared (TIR) spectral imagery data
Real-time visualization of the impact of changes in model parameters on the fit between observed and model radiance spectra.
Graphical Processing Unit (GPU) implementation of MODTRAN’s TIR radiance algorithms integrated into an interactive toolkit for retrieving and mapping the 3-D composition of atmospheric plumes using JPL established retrieval algorithms.
Achieve 100 fold run-time reduction of radiative transfer calculations vs. state-of-the-art MAP_SO2 model.
