What is Eradiate?#
Eradiate is a modern radiative transfer model for Earth observation applications. It primarily targets calibration/validation applications and focuses on delivering highly accurate results.
Eradiate is built around a radiometric kernel based on the Mitsuba 3 rendering system. It provides abstractions to conveniently build scenes, manage kernel runs and collect results.
Features: What can I do with Eradiate?#
- Perform monochromatic and band simulations.
Eradiate can simulate radiative transfer for a single wavelength or a spectral band (using the correlated-k distribution method) between 280 and 2400 nm.
- Perform simulations on one-dimensional scenes.
Eradiate can simulate top-of-atmosphere radiance and reflectance on 1D scenes with plane parallel geometry. These scenes consist of a smooth surface underneath an atmosphere including gases and an arbitrary number of aerosol layers. Under the hood, Eradiate performs these simulations using 3D scenes carefully designed to produce results similar to what one would get with 1D geometries.
Eradiate has experimental support for spherical shell geometries (validation is in progress).
- Perform simulations on three-dimensional scenes.
Eradiate can simulate top-of-canopy/atmosphere radiance on 3D scenes consisting of a vegetated ground patch with or without atmosphere above it (plane parallel geometry only).
