The Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors are sensitive to noise from local environmental sources, such as thunderstorms. We developed a method to identify thunderclaps using feature extraction and machine learning algorithms. In combination with ground motion data, we identify thunderstorm segments. We tested the tool in LIGO-Livingston data and found that, during thunderstorms, this detector experienced losses up to approximately 15% in its sensitivity.
