                         Waves and oscillatory phenomena have been observed in the solar 
                         atmosphere as mechanisms that transfer energy through its 
                         different heights, from the photosphere to outer layers. Hence, 
                         they are considered as one of the main processes responsible for 
                         heating the upper solar atmosphere. This study aims to detect and 
                         characterize various MHD wave modes in a sunspot atmosphere (i.e., 
                         active region AR12533), based on high-resolution observations with 
                         the Swedish 1-m Solar Telescope (SST), complemented by 
                         co-observations with the Interface Region Imaging Spectrograph 
                         (IRIS) and the Solar Dynamic Observatory (SDO) space missions. The 
                         SST observations sample various atmospheric heights in the lower 
                         atmosphere, taken in multiple wavelength positions of the Ca II 
                         852.2 nm (in full Stokes) and H\α 656.3 nm spectral line. 
                         The MHD waves are traced throughout the solar atmosphere by 
                         analysing temporal evolution in intensities and Doppler velocities 
                         and shifts in wave frequency. This poster presents the preliminary 
                         results and outlines the next steps of these waves propagation
