abstract = "The plasma beta is important in the investigation of interchanging
roles of plasma and magnetic pressure in the solar atmosphere. It
can help to describe features over the photosphere and their
changes at different heights. The goal of this paper is to obtain
the plasma beta variations through the solar corona during solar
cycles 23 and 24. The plasma beta is reconstructed in different
layers of the solar atmosphere. For this purpose, we use an
updated version of the COronal DEnsity and Temperature model. In
this version we selected different features in the solar
atmosphere such as quiet-Sun (QS), faculae, and active regions. We
calculate the beta variations at different layers in the solar
corona (R = 1.14, 1.19, 1.23, 1.28, 1.34, 1.40, 1.46, 1.53, 1.61,
1.74, 1.79, 1.84, and 1.90 R-circle dot). In the photosphere we
use temperature values from the FALC model to obtain plasma beta
in QS and faculae. Additionally, variations of the magnetic and
kinetic pressure were modeled during the last solar cycles at
coronal heights.",
