Error 2: Signals have too low S/N Ratio 2. Check connections to the microphones, and especially the weatherproofing around the mics. The rain might be causing too much noise in the signal. Also check if there is some device that might be corrupting the sounds signal.
Error 3: Could not reconstruct lightning 3. The algorithm could not construct lightning information with high enough confidence. This could be caused by weather anomalies, interference, and/or poor recording conditions (ex. high winds, multiple close together lightning strikes, etc)
