N2 - This paper investigates terahertz (THz) channel propagation characteristics and explores their potential for environment sensing. Employing controlled experimental setups utilizing THz time-domain spectroscopy (THz-TDS) and continuous wave (CW) systems, we examine THz sensitivity to atmospheric phenomena and surface textures. A convolutional neural network (CNN) model trained on measured attenuation data demonstrates efficiency in rainfall intensity estimation, achieving a mean absolute percentage error (MAPE) of 7.47%. Furthermore, a Long Short-Term Memory (LSTM) neural network robustly classifies surface roughness under dynamic, high-speed conditions, maintaining classification accuracies above 90% even at simulated urban vehicle speeds.
