Atmospheric radiative transfer codes

A radiative transfer model is a mathematical model with the aid of the reflection, transmission and absorption operations of an object can be simulated.

Radiation- transfer models have been developed for various Erdsphären:

• Phytosphere: vegetation (agricultural crop stocks, forests and forestry )
• Pedosphere: Flooring
• Aqua sphere: water surfaces (lakes, oceans )
• Atmosphere

Applications

Radiative transfer models are very often used in remote sensing. There are two principal applications:

• Direct mode
• Inverse fashion

In direct mode, the spectral reflectance properties of an object, for example, simulated to determine spectral channels that allow optimal detection of the most important object properties. In this case, one would speak of a sensitivity analysis.

In the inverse mode measured reflection characteristics of an object are used for the parameters of the radiative transfer model (and thus the characteristics of the object ) to be determined. In this case one speaks of a model inversion.

In addition to the remote sensing radiation transfer models used in other areas of application, such as planetology, meteorology and climatology, but also in industrial applications.
