Impact of Horizontal Resolution on the Robustness of Radiation Emulators in a Numerical Weather Prediction Model

Remote Sensing, 2023
Developing a machine-learning-based radiative transfer emulator in a weather forecasting model is valuable because it can significantly improve the computational speed of forecasting severe weather events.

The impact of coupled 3D shortwave radiative transfer on surface radiation and cumulus clouds over land [PDF]

Atmospheric Chemistry and Physics
Radiative transfer is a 3D process, but most atmospheric models consider radiation only in the vertical direction for computational efficiency. This results in inaccurate surface radiation fields, as the horizontal transport of radiation is neglected ...

Radiative Transfer in Lyα Nebulae. I. Modeling a Continuous or Clumpy Spherical Halo with a Central Source

The Astrophysical Journal, 2023
To understand the mechanism behind high- z Ly α nebulae, we simulate the scattering of Ly α in a H i halo about a central Ly α source. For the first time, we consider both smooth and clumpy distributions of halo gas, as well as a range of outflow speeds,

Retrieval of sea surface temperature from space based on modeling of infrared radiative transfer: capabilities and limitations [PDF]

, 2004
The retrieval (estimation) of sea surface temperatures (SSTs) from space-based infrared observations is increasingly performed using retrieval coefficients derived from radiative transfer simulations of top-of-atmosphere brightness temperatures (BTs ...

A Refined Four-Stream Radiative Transfer Model for Row-Planted Crops

Remote Sensing, 2020
In modeling the canopy reflectance of row-planted crops, neglecting horizontal radiative transfer may lead to an inaccurate representation of vegetation energy balance and further cause uncertainty in the simulation of canopy reflectance at larger ...

An implementation of radiative transfer in the cosmological simulation code gadget [PDF]

Monthly Notices of the Royal Astronomical Society, 2009
We present a novel numerical implementation of radiative transfer in the cosmological smoothed particle hydrodynamics (SPH) simulation code {\small GADGET}. It is based on a fast, robust and photon-conserving integration scheme where the radiation transport problem is approximated in terms of moments of the transfer equation and by using a variable ...
