Description
We investigate the seasonal variability of atmospheric infrasound and its impact on Newtonian noise (NN) at the Sos Enattos site, a candidate location for the Einstein Telescope. Measurements from surface and underground stations are used to characterize both temporal changes and the depth dependence of the acoustic field. Clear seasonal variations are observed, primarily driven by changing wind conditions. Using the measured pressure data, we estimate the corresponding NN contribution and its attenuation with depth. The results show a strong suppression of infrasound-induced NN in underground environments. In all analyzed conditions, the NN level remains well below the expected sensitivity of the detector, indicating that atmospheric infrasound is not a limiting noise source at this site.
