What other observing systems can complement wind profilers?
The restriction of wind profiler radars to measure wind only (and not, as in the case with conventional radiosondes, to include other atmospheric characteristics like temperature, humidity and pressure) caused some hesitation in applying wind profiler radars in operational services. Future work will be aimed at integrating other ground-based remote sensing techniques with wind profilers. In the last few years, new equipment like Differential Absorption Lidar, Microwave Radiometer, GPS-Receiver, Fourier Transform Infrared Radiometer, and Optic Spectrometers have been developed to monitor, e.g., the structure of the atmospheric water vapor field.
