Status of ISO-DIS 21348 for synthetic solar spectral irradiance models.
Abstract
We present the current methodology in place for our development and production use of synthetic models of the solar spectral irradiance (Fontenla et al. 1999, Fox et al. 2004). The goal of the synthesis is the successful combination of realistic representations of the observed solar disk with semi-empirical models and the theory for calculation of a mixed line+continuum solar spectrum in specific spectral bands in the UV, visible, and near-IR. Each stage of the process is discussed within the context of compliance with the DIS. The complete model development includes a number of stages: analysis of high precision photometric solar images and magnetograms, calculation of emission, absorption, and transfer of radiation in the solar atmosphere based on semi-empirical thermodynamics models and several sources of atomic and molecular data, and the production of databases of component models of the solar spectral radiances, and irradiances for ranges of solar magnetic activity levels.
