Modeling of radiative energy transfer dynamics

Radiative Energy Transfer with Filter

An ideal blackbody resides inside a cavity in a medium of temperature T that is also an ideal blackbody. If the small black body is initially at temperature T could its temperature evolve to an equilibrium temperature T ′ different from T if the inner surface of the cavity is covered with a passive filter? For example, the filter might be an ideal transmitter for light of wavelength λ < λf (or ...

Radiative Transfer Modeling of Lunar Hyperspectral Data

Introduction: One of the current goals of the Selenoligcal and Engineering Explorer “KAGUYA” (SELENE) and the Moon Mineralogy Mapper (M, aboard Chadrayaan-1) missions is the accurate determination of surface composition. These data are being collected with the knowledge that when light interacts with an airless body surface it is either absorbed or reflected in a way unique to each of the most ...

Radiative Transfer Modeling of the Martian Atmosphere

Introduction: Studies of the past and current climate and weather on Mars depend on accurate calculations of the radiative properties of the Martian atmosphere. Atmospheric and Environmental Research, Inc. (AER) is the source of the state-of-the-science radia-tive transfer codes for terrestrial applications [1] and these models are continuously updated and validated [2]. Recently, they have bee...

Radiative energy transfer in compressible turbulence

This Letter investigates the compressible energy transfer process. We extend a methodology developed originally for incompressible turbulence and use databases from numerical simulations of a weak compressible turbulence based on Eddy-DampedQuasi-Normal-Markovian (EDQNM) closure. In order to analyze the compressible mode directly, the well known Helmholtz decomposition is used. While the compre...
