EaR³T (pronounced /ɜːt/) is a Python software package developed for cutting-edge radiative transfer and remote sensing applications. It provides high-level interfaces to automate the process of performing IPA/3D radiative transfer calculations for measured or modeled cloud/aerosol fields using publicly available radiative transfer solvers. The automation capability covers not only the simulation of radiometric quantities such as radiance and irradiance, but also the downloading/processing of satellite data and the setup of atmospheric radiative properties, which are essential for an end-to-end simulation pipeline.

• Spaceborne and airborne remote sensing;
• 3D radiative effects (of clouds, aerosols, and trace gases etc.);
• Synthetic data generation (for CNN training);
• Novel retrieval algorithm development (e.g., CNN-based).
