Comparison of turbulence measurements by a CSAT3B sonic anemometer and a high-resolution bistatic Doppler lidar

Abstract: Abstract. Accurate measurements of turbulence statistics in the atmosphere are important for eddy-covariance measurements, wind energy research, and the validation of atmospheric numerical models. Sonic anemometers are widely used for these applications. However, these instruments are prone to probe-induced flow distortion effects, and the magnitude of the resulting errors has been debated due to the lack of an absolute reference instrument under field conditions. Here, we present the results of an intercompar… Show more

“…To date, the discussion in the literature about possible systematic errors of flux measurements using sonic anemometers is still ongoing (Kochendorfer et al 2012;Horst et al 2015;Frank et al 2016), indicating that the error might be on the order of 3-5% for the energy fluxes. New experimental designs have recently been explored to employ additional independent reference estimates for sonic anemometers, particularly under turbulent conditions, such as large-eddy simulation (LES, Huq et al 2017), spectral ratios in the inertial sub-range (Peña et al 2019), and high-resolution Doppler lidar (Mauder et al 2020). While the absolute accuracy of sonic anemometers is still not fully quantified, it was at least established that the precision of various types of modern sonic anemometers is very good regarding general flux measurements (Mauder and Zeeman 2018).…”

“…In 2019, a comparative measurement between the PTB bistatic lidar and a CSAT3B ultrasonic anemometer mounted on top of a 30 m mast was conducted over flat terrain at the site of the Johann Heinrich von Thünen Institut (the German Federal Research Institute for Rural Areas, Forestry and Fisheries) in Braunschweig, Germany [3]. At this height, the PTB bistatic lidar's measurement volume (diameter d = 2 mm and length l = 50 mm) is comparable to that of the used sonic anemometer.…”

“…Accurate wind velocity measurements are an essential prerequisite for many applications in the field of wind energy and meteorology, such as wind potential analysis [1], the power curve evaluations of wind turbines [2] and atmospheric turbulence analysis [3]. For example, low measurement uncertainties are especially desired for reliable resource assessments of projected wind farms because the wind turbine power output scales with the third power to the wind velocity [4].…”

“…We compared our wind measurements with the bistatic Doppler lidar, developed at the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, Germany (Oertel et al, 2019;Mauder et al, 2020). A data output rate of 10 Hz was used in the PTB lidar, and different heights between 20 and 100 m were tested.…”
