Presented are some results with 3D radiation (TenStream) in an idealized gaussian hill simulation in WRF-LES. The results show the capability to run with terrain following sigma coordinate meshes and highlight the importance of 3D radiative transfer effects beyond just using a slope correction of surface irradiances

Setup

terrain following sigma-coordinate mesh — each voxel is a Parallelepiped

Results

1D 1D + slope correction 3D Tenstream
