Modeling the solar spectral irradiance
International audience Modeling the solar spectral irradiance is necessary for different fields: solar, atmospheric and climate physics. In general, the reconstructions aim to generate the solar spectral irradiance (SSI) at a time where no measurement exists. Therefore, they are based on different s...
