Tilt-correction algorithms for 3D sonic anemometers

Tilt-correction algorithms for 3D sonic anemometers

The present Matlab code includes some algorithms to correct tilt angle errors from sonic anemometers, including the method by Wilczak et al. [1]. Other methods are the double and triple rotation algorithm.

The present submission contains :

• 4 example files: one for the planar fit algorithm, one for the double rotation, one for the triple rotation and one for the estimation of the friction velocity with the different retrieval algorithms.

• The function tiltCorrection.m

• The function friction_velocity.m

• the file data.mat that includes simulated wind data

Any comment, question or suggestion to improve the algorithm is warmly welcomed.
