Solar atmospheric model with spicules applied to radio observation

摘要: An atmospheric model was constructed in order to reproduce quantitatively the observations at 17 GHz from Nobeyama Radio Heliograph, namely brightness temperature disk center (from 1.4 400 GHz), center-to-limb bright- ening distribution, and radius derived solar maps. The two dimensional model, that takes into account curvature of Sun, includes spicules, which physical characteristics (such as size, temperature, density, position, inclination angle) were randomly attributed. After interferometer instrumental response is taken account, results showed than an without spicules produces 36% limb brightening, approximately value observed poles. However, inferred (970 �� )w 6 smaller mean improvement made by including spicules. Results this upgraded depending on their parameters, brightening values are obtained agreement with radio (except for polar regions).
