چکیده
The reconstruction of the solar spectral irradiance (SSI) on various time scales is essential for understanding Earth's climate response to SSI variability. driver variability understood be intensity contrast magnetic features present Sun with respect largely non-magnetic quiet Sun. However, different synthesis codes lead diverging projections In this study we compare three radiative transfer and carry out a detailed analysis their performance. We perform at continuum wavelength 665 nm Code Solar Irradiance (COSI), Rybicki-Hummer (RH), Max Planck University Chicago Radiative MHD (MURaM) 3D simulations snapshots, case, 100 G, 200 G field strength. determine distributions, differences ratios codes. identify that largest discrepancies originate in intergranular lanes where most concentration occurs. Overall, applied give consistent distributions. Also, variation as function strength particular snapshots agree within 2-3% range.

Polarized Radiative Transfer in Solar Atmosphere
The observations indicate the existence of linear polarization in the hydrogen Hα spectral line observed during the solar flare events. This emission of polarized radiation is of the order of 5% and is usually explained as a consequence of collisions of hydrogen atoms with the beam of fast protons coming from coronal regions. This article presents a brief overview of the recent solar flare pola...
متن کاملRadiative Transfer in 3D Numerical Simulations
We simulate convection near the solar surface, where the continuum optical depth is of order unity. Hence, to determine the radiative heating and cooling in the energy conservation equation, we must solve the radiative transfer equation (instead of using the diffusion or optically thin cooling approximations). A method efficient enough to calculate the radiation for thousands of time steps is n...
متن کاملSlow magnetohydrodynamic waves in the solar atmosphere.
There is increasingly strong observational evidence that slow magnetoacoustic modes arise in the solar atmosphere, either as propagating or standing waves. Sunspots, coronal plumes and coronal loops all appear to support slow modes. Here we examine theoretically how the slow mode may be extracted from the magnetohydrodynamic equations, considering the special case of a vertical magnetic field i...
متن کاملEffects of bias in solar radiative transfer codes on global climate model simulations
[1] Codes commonly used in climate and weather prediction models for calculating the transfer of solar radiation in the atmosphere show systematic differences amongst each other, and even the best of codes show systematic differences with respect to observations. A 1-dimensional radiative-convective equilibrium model is used to show the effects of such bias on the global energy balance and on t...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
