In this work we use solar observations with the ALMA radio telescope at the wavelength of 1.21 mm. The aim of the analysis

is to improve understanding of the solar chromosphere, a dynamic layer in the solar atmosphere between the photosphere and

corona. The study has an observational and a modeling part. In the observational part full-disc solar images are analyzed.

Based on a modied FAL atmospheric model, radiation models for various observed solar structures are developed. Finally, the

observational and modeling results are compared and discussed.
