Eradiate is a software package for three-dimensional radiative transfer modeling tailored to Earth observation applications. It is funded by the Copernicus Programme through a project managed by the European Space Agency (Contract No. 40000127201/19/I-BG). Eradiate uses the Mitsuba 3 renderer, developed by the Realistic Graphics Lab, taking advantage of its Python interface and proven architecture, and extends it with components implementing numerical methods and models used in radiative transfer for Earth observation. For comprehensive information about Eradiate—including download and installation instructions, detailed user documentation, and background on the development team—please visit the project website.
Figures below provide the Eradiate 3D radiative transfer simulations conducted within the ESA project DTE-S2GOS. The scene represents a 10 km wide area in Patagonia National Park, Chile, and was generated using a scene generator that integrates land cover data, a digital elevation model, Terrestrial Laser Scanning (TLS) data provided by the Ghent University , a spectral surface albedo library, and atmospheric information from the Copernicus Atmosphere Monitoring Service (CAMS). The solar geometry was accurately prescribed according to the selected date and time. The RGB rendering (left) and the simulated Sentinel-2 RGB composite (right) depict largely consistent representations of the same scene.
