Tilt-correction algorithms for 3D sonic anemometers

View Sonic anemometer tilt correction algorithm on File Exchange


The present submission includes some algorithm 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.
