Abstract:
1. A system for correcting wind speed and direction data collected by a sodar or lidar apparatus for at least the orientation of the apparatus, comprising: one or more sensors mounted to the sodar or lidar apparatus that detect at least the three-dimensional angular orientation of the apparatus; a processor that uses the detected three-dimensional angular orientation and a correction algorithm to correct in situ the wind speed and direction data in three dimensions for deviations from some nominal orientation, and that detects failures of the one or more sensors and in response to the detection of a failure uses the last valid orientation information to correct the wind speed and direction data; and a database that stores; an identification of the correction algorithm; the detected three-dimensional angular orientation of the apparatus; and the corrected wind speed and direction data.
