             abstract = "The Total Solar Irradiance (TSI) is the radiation generated by the 
                         Sun in different wavelengths and received by the Earth (1AU). This 
                         radiation affects the Earth's climate on large time scales. The 
                         accurate values of the solar irradiance are important in climate 
                         and atmospheric models. The Total Solar Irradiance (TSI) were 
                         considered constant with a value approximately \∼ 1.361 
                         Wm-2, but observations have revealed some variations in different 
                         time scales. These observations are restricted to the last few 
                         solar cycles and are subject to large uncertainties. We present a 
                         model to reconstruct in near-real time the evolution of the Total 
                         Solar Irradiance based on the solar surface magnetic field from 
                         the Helioseismic and Magnetic Imager (HMI) on board the Solar 
                         Dynamics Observatory (SDO) at 6173 A with a resolution of one 
                         arcsecond. Our model is based on the assumption that the 
                         irradiance variability is due to the evolution of the solar 
                         magnetic field. We employ a Layer-Recurrent Network (LRN) to model 
                         the relationship between the complex evolution of the photospheric 
                         magnetic field and the solar irradiance. The input parameters are 
                         determined from observations, the magnetic structures are 
                         identified and classified according to the area of the solar disk 
                         covered. This reconstruction of the total irradiance (TSI) in near 
                         real time is available on the website of the Estudo e 
                         Monitoramento Brasileiro Do Clima Espacial (EMBRACE) at the
