The Passive Aquatic Listener (PAL) is a passive underwater acoustic recorder that measures precipitation rates and wind over the ocean. It collects underwater ambient-noise time series and converts them into a multi-frequency (1-50 kHz) spectrum of sound pressure levels (SPLs). These SPLs can be used to determine the intensity of ambient ocean sounds, such as raindrops and surface winds, and to estimate rain rate and wind speeds. PAL provides data as a 4.5 s time series sampled at 100 kHz. PAL can be deployed on moored buoys and floats.
