Radiative transfer model (RTM)

In PALM, the radiative interactions within urban canopy are solved by the separate Radiative transfer model (RTM, see Krč et al. 2021), which provides explicit 3-D modelling of multi-reflective radiative exchange among the sun, the sky, urban surfaces and resolved plant canopy, and it also provides radiative inputs for the Biometeorology module (BIO) and for photolysis in the Chemistry model (CHEM). The RTM is coupled to the selected Radiation model, which provides radiation above the urban canopy as an input.
