Remote Sensing (Sodar)
Sodar stands for Sonic Detection And Ranging. It works by sending out a sound pulse and recording the reflections scattered back off the atmosphere. The change is sound frequency of the reflection is converted into wind conditions and the time it takes to detect the returned sound indicates the height of the measurement.
The Fulcrum3D Sodar provides data on wind conditions including wind speed, wind direction, wind speed standard deviation and inflow angle (related to vertical wind speed).
The Fulcrum3D Sodar is different to most Sodar devices available on the market. The main features are listed below:
– Specifically designed for use in complex terrain. – Accurate and highly validated by independent consultants. – Fixed beam angles for greater consistency between sites. – Full raw data capture allows historic data to be reprocessed with updated firmware. – Fully integrated power supply and communications included in price.
The unit has been used in a variety of deployments over four continents ranging from two week verifications to multiyear campaigns. These have covered both simple and complex terrain, operations between -10º to 50ºC and in both dessert and tropical locations.
