Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights roundup. For November, the Divisions we are featuring are: Earth Magnetism & Rock Physics (EMRP), Geodynamics (GD) and Tectonics and Structural Geology (TS). They are served by the journals: Geoscientific Model Development (GMD) and Solid Earth (SE).
Geoscientific Model Development:
HORAYZON v1.2: an efficient and flexible ray-tracing algorithm to compute horizon and sky view factor – 28 November 2022
Terrain horizon and sky view factor are crucial quantities for many geoscientific applications; e.g. they are used to account for effects of terrain on surface radiation in climate and land surface models. Because typical terrain horizon algorithms are inefficient for high-resolution (< 30 m) elevation data, we developed a new algorithm based on a ray-tracing library. A comparison with two conventional methods revealed both its high performance and its accuracy for complex terrain.
