Parameter optimization for surface flux transport models [PDF]
Astronomy & Astrophysics, 2017 Accurate prediction of solar activity calls for precise calibration of solar cycle models. Consequently we aim to find optimal parameters for models which describe the physical processes on the solar surface, which in turn act as proxies for what occurs in the interior and provide source terms for coronal models.

Modelling thermal fluxes at the soil surface [PDF]
Environmental Geotechnics, 2019 This paper investigates the impact that various representations of thermal fluxes at the soil surface have on the estimation of seasonal variations in temperature and stored thermal energy in the soil close to the surface. Three theoretical formulations representing turbulent, non-turbulent and vegetation-covered soil surface conditions are considered.

The land-surface flux model PROGSURF [PDF]
Global and Planetary Change, 1998 Abstract The land-surface flux model (PROGSURF) designed jointly at the Universities of Vienna and Budapest is reviewed; it belongs to the broad spectrum of PILPS 1 models. PROGSURF comprises one vegetation layer and three soil layers. Temperature prediction is made by the heat conduction equation in conjunction with the force-restore method ...

Model Predictions and Visualization of the Particle Flux on the Surface of Mars [PDF]
Journal of Radiation Research, 2002 Model calculations of the particle flux on the surface of Mars due to the Galactic Cosmic Rays (GCR) can provide guidance on radiobiological research and shielding design studies in support of Mars exploration science objectives. Particle flux calculations for protons, helium ions, and heavy ions are reported for solar minimum and solar maximum ...

The Simulation of Surface Heat Fluxes in a Land SurfaceAtmosphere Model [PDF]
Journal of Applied Meteorology, 1995 Abstract A modified soil-canopy-boundary layer model based on Ek and Mahrt is presented to simulate surface heat fluxes on a daily basis. The model is validated against independent published bare soil data from Agassiz, Canada, and observations taken over sparse and dense vegetation as part of the HAPEX-MOBILHY (Hydrological Atmospheric Pilot ...
