Since it launched in 1995, has taken a unique approach to weather forecasting, relying on both data from public agencies and a sprawling network of citizen scientists using their own personal weather stations. The sticky humidity and heat that’s bothering apartment dwellers in urban basins in the southwest aren’t fun, but up in the mountains they could easily trigger surprise thunderstorms and monsoon rains, not to mention dangerous flash floods in the canyons below - even when the skies are clear. Beyond filling the time with idle small talk at the water cooler, weather reports can have a huge affect on our trail time plans … and many times, those weather conditions are more than an inconvenience - they can be downright life threatening.

Velocity measurements from up to nine cells are used, along with measured water level, to calculate discharge either internally in the OTT SLD or externally in a data logger.As someone who spends a significant amount of time outside, odds are you probably pay a bit more attention to weather reports and forecasts than your Average Joe Coworker.

All measurement values are analyzed, verified and processed by an integrated signal processor, before being used in the calculation of discharge.

An optional vertical transducer and integrated pressure cell measures the water level.

Equipped with two horizontal ultrasonic transducers “looking sideways” into the flow (Side Looking Doppler) to measure water velocity.
