Concurrent Calculation of Radiative Transfer in the Atmospheric Simulation in ECHAM-6.3.05p2 [PDF]

Geoscientific Model Development, 2021
Abstract. The scalability of the atmospheric model ECHAM6 at low resolution, as used in palaeoclimate simulations, suffers from the limited number of grid points. As a consequence, the potential of current high performance computing architectures cannot be used at full scale for such experiments, particularly within the available domain-decomposition ...

Radiative forcing since preindustrial times due to ozone change in the troposphere and the lower stratosphere [PDF]

, 2006
Changes in atmospheric ozone have occurred since the preindustrial era as a result of increasing anthropogenic emissions. Within ACCENT, a European Network of Excellence, ozone changes between 1850 and 2000 are assessed for the troposphere and the lower ...

A MODEL TO SIMULATE THE RADIATIVE TRANSFER OF FLUORESCENCE IN A LEAF [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Abstract. Light is reflected, transmitted and absorbed by green leaves. Chlorophyll fluorescence (ChlF) is the signal emitted by chlorophyll molecules in the leaf after the absorption of light. ChlF can be used as a direct probe of the functional status of photosynthetic machinery because of its close relationship with photosynthesis.

Calculation of the radiance distribution at the boundary of an isotropically scattering slab [PDF]

, 1997
The radiance arising from an anisotropically scattering illuminated stack of n slabs is calculated using the equation of radiative transfer. It appears to be unnecessary to calculate the radiance inside the material; including only the radiance at the ...

Simulation of SEVIRI infrared channels: a case study from the Eyjafjallajökull April/May 2010 eruption [PDF]

Atmospheric Measurement Techniques, 2013
Infrared satellite images are widely and successfully used to detect and follow atmospheric ash from erupting volcanoes. We describe a new radiative transfer model framework for the simulation of infrared radiances, which can be compared directly with ...

Is a scaling factor required to obtain closure between measured and modelled atmospheric O₄ absorptions? An assessment of uncertainties of measurements and radiative transfer simulations for 2 selected days during the MAD-CAT campaign [PDF]

Atmospheric Measurement Techniques, 2019
In this study the consistency between MAX-DOAS measurements and radiative transfer simulations of the atmospheric O4 absorption is investigated on 2 mainly cloud-free days during the MAD-CAT campaign in Mainz, Germany, in summer 2013.

ARTS, the atmospheric radiative transfer simulator

Journal of Quantitative Spectroscopy and Radiative Transfer, 2005
Abstract ARTS is a modular program that simulates atmospheric radiative transfer. The paper describes ARTS version 1.0, which is applicable in the absence of scattering. An overview over all major parts of the model is given: calculation of absorption coefficients, the radiative transfer itself, and the calculation of Jacobians.

Radiative forcing in the 21st century due to ozone changes in the troposphere and the lower stratosphere [PDF]

, 2003
Radiative forcing due to changes in ozone is expected for the 21st century. An assessment on changes in the tropospheric oxidative state through a model intercomparison ("OxComp'') was conducted for the IPCC Third Assessment Report (IPCC-TAR).
