The Venus Global Ionosphere-Thermosphere Model (V-GITM): A Coupled Thermosphere and Ionosphere Formulation

Bougher, Stephen W.; Ridley, Aaron J.; Ponder, Brandon M. +2 more

This paper introduces the new Venus global ionosphere-thermosphere model (V-GITM) which incorporates the terrestrial GITM framework with Venus-specific parameters, ion-neutral chemistry, and radiative processes in order to simulate some of the observable features regarding the temperatures, composition, and dynamical structure of the Venus atmosph…

Three-Dimensional Venus Cloud Structure Simulated by a General Circulation Model

Shao, Wencheng D.; Dai, Longkang; Mendonça, João. M.

The clouds have a great impact on Venus's energy budget and climate evolution, but its three-dimensional structure is still not well understood. Here we incorporate a simple Venus cloud physics scheme into a flexible GCM to investigate the three-dimensional cloud spatial variability. Our simulations show good agreement with observations in terms o…
