complex flow mapMeteodyn and ZephIR Lidar have collaborated to produce a packaged “white box” solution for more effective wind measurements in complex terrain. In strongly non-uniform flow, for example in complex terrain, measurements are often not the same across the scanned area and wind speeds measured by remote sensors will not necessarily be comparable to that experienced by traditional anemometry at the scan centre.

A similar effect would be seen if comparing two met masts spaced some small distance apart in complex terrain – they are simply measuring different conditions that depends on their precise location. Meteodyn and ZephIR Lidar have conducted a validation study lasting more than 18 months utilising multiple years of data in order to deliver a white box solution when taking measurements in complex terrain. By using Meteodyn WT in complex terrain, a set of ‘factors’ can be computed that enable the conversion of measurements from a bankable ZephIR 300 wind lidar into comparable point measurements similar to those from conventional anemometry. This auditable white box process enables the traceability required by consultants for continued project financing based on data from ZephIR 300 alone by reducing the uncertainty between remote sensors and traditional anemometry in complex terrain. Existing Meteodyn WT users, in addition to any ZephIR Lidar user, can access the white box solution.
