What does the Kilo index measure?

The Kilo index specifically measures temporal or geomagnetic noise, which is essential in the context of underwater acoustics and oceanography. Temporal noise arises from various environmental factors and can significantly affect acoustic measurements. By focusing on geomagnetic noise, which is related to the Earth's magnetic field fluctuations, the Kilo index helps in identifying and quantifying disturbances that might interfere with acoustic signal processing.

Identifying these noise levels is critical for ensuring accurate data analysis and interpretation in oceanographic studies, particularly in the detection of submarines or other underwater objects, where clarity of acoustic signals is paramount. The Kilo index thereby serves as an important metric in understanding the acoustic environment and mitigating the impact of external noises on operational effectiveness.
