Summary

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.

Content

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.
