crash: a radiative transfer scheme [PDF]

Monthly Notices of the Royal Astronomical Society, 2003
We present a largely improved version of CRASH, a 3-D radiative transfer code that treats the effects of ionizing radiation propagating through a given inhomogeneous H/He cosmological density field, on the physical conditions of the gas. The code, based on a Monte Carlo technique, self-consistently calculates the time evolution of gas temperature and ...

Spherical Harmonics for the 1D Radiative Transfer Equation. I. Reflected Light

The Astrophysical Journal, 2023
A significant challenge in radiative transfer theory for atmospheres of exoplanets and brown dwarfs is the derivation of computationally efficient methods that have adequate fidelity to more precise, numerically demanding solutions.

On the Integration of the Equation of Radiative Transfer. [PDF]

The Astrophysical Journal, 1938
The equation of the radiative transfer has been integrated by a generalization of Spitzer's method, which makes use of Bessel functions.

Analysis of the Discrete Theory of Radiative Transfer in the Coupled “Ocean–Atmosphere” System: Current Status, Problems and Development Prospects

Journal of Marine Science and Engineering, 2020
In this paper, we analyze the current state of the discrete theory of radiative transfer. One-dimensional, three-dimensional and stochastic radiative transfer models are considered.

Three‐Dimensional Radiative Effects By Shallow Cumulus Clouds on Dynamic Heterogeneities Over a Vegetated Surface

Journal of Advances in Modeling Earth Systems, 2020
One‐dimensional radiative transfer solvers are computationally much more efficient than full three‐dimensional radiative transfer solvers but do not account for the horizontal propagation of radiation and thus produce unrealistic surface irradiance ...

Neighboring Column Approximation—An Improved 3D Thermal Radiative Transfer Approximation for Non‐Rectangular Grids

Journal of Advances in Modeling Earth Systems, 2020
We present a significantly improved version of the Neighboring Column Approximation (NCA 2.0), a fast 3D approximation for the calculation of thermal heating and cooling rates in cloudy atmospheres for large eddy simulation models.

Fast and simple model for atmospheric radiative transfer [PDF]

, 2010
Radiative transfer models (RTMs) are of utmost importance for quantitative remote sensing, especially for compensating atmospheric perturbation. A persistent trade-off exists between approaches that prefer accuracy at the cost of computational complexity,

The I3RC - Bringing Together the Most Advanced Radiative Transfer Tools for Cloudy Atmospheres [PDF]

, 2005
The interaction of clouds with solar and terrestrial radiation is one of the most important topics of climate research. In recent years it has been recognized that only a full three-dimensional (3D) treatment of this interaction can provide answers to ...
