ZephIR 300M wind lidar firmware intercomparison

We have performed an intercomparison between two ZephIR 300M wind lidars instrument at the Cabauw site, in order to verify the new ZX firmware in comparison to the old ZP firmware. In general, within the specified accuracy of the manufacturer no significant differences where observed in the output of the two wind lidars, considering the 10-minute averaged data of the horizontal wind speed and wind direction. Additional features of the ZX firmware are also discussed, such as the quality controlled unaveraged data, and consequences in the filesize and MODBUS application.
