The importance of time-dependent MHD solar wind simulations in the frame of the PUNCH mission

In preparation for the PUNCH mission which is planned to be launched in 2025, we construct synthetic white light (WL) images of the inner heliosphere based on GAMERA 3D MHD output. GAMERA is a 3D MHD code whose capabilities have been extended to perform time-dependent solar wind simulations by frequently updating the input magnetograms and thus the boundary conditions at the inner boundary of the code, offering a much more realistic reconstruction of the solar wind propagation and evolution. By employing this capability, we explain the phenomena and structures of the solar wind we see in the synthetic WL images from multiple view points (ACE, STEREO, PUNCH) and compare with the traditional steady state MHD approach.
