act.corrections.correct_wind(ds, wspd_name='wind_speed', wdir_name='wind_direction', heading_name='yaw', cog_name='course_over_ground', sog_name='speed_over_ground')[source]#

This procedure corrects wind speed and direction for ship motion based on equations from NOAA tech. memo. PSD-311. A Guide to Making Climate Quality Meteorological and Flux Measurements at Sea. https://www.go-ship.org/Manual/fluxhandbook_NOAA-TECH%20PSD-311v3.pdf

Parameters:

  • ds (xarray.Dataset) – The ceilometer dataset to correct. The backscatter data should be in linear space.

  • wspd_name (string) – Wind speed variable name.

  • wdir_name (string) – Wind direction variable name.

  • heading_name (string) – Navigiation heading variable name.

  • cog_name (string) – Course over ground variable name.

  • sog_name (string) – Speed over ground variable name.

Returns:

ds (xarray.Dataset) – The Xarray dataset containing the corrected values.
