Next generation combined sonic-hotfilm anemometer: wind alignment and automated calibration procedure using deep learning

The study of naturally occurring turbulent flows requires ability to collect empirical data down the fine scales. While hotwire anemometry offers such ability, open field studies are uncommon due cumbersome calibration procedure and operational requirements anemometry, e.g., constant ambient properties steady flow conditions. combo probe-the combined sonic-hotfilm anemometer developed tested over last decade-has demonstrated its overcome this hurdle. old-er generation had a limited wind alignment range 120 degrees in-situ was human decision based. This presents next probe design, new fully automated implementing deep learning. elegant design now enables measurements incoming in 360-degree range. improved is shown have robustness necessary for operation everchanging environmental especially useful with diurnally changing environments or non-stationary measuring stations, i.e., probes placed on moving platforms like boats, drones, weather balloons. Together, updated procedure, allow continuous minimal no interaction, enabling near real-time monitoring fine-scale fluctuations. Integration these will contribute toward large pool be collected unravel intricacies all scales natural setups.
