The update will consist of the inclusion of a new wind variable.

This new wind variable is computed with Gourrion (2002) algorithm using Collard (2005) table.

The algorithm is based on: Gourrion, J., D. Vandemark, S. Bailey, B. Chapron, G. P. Gommenginger, P. G. Challenor, and M. A. Srokosz, 2002. A two-parameter wind speed algorithm for Ku-Band altimeters, J. Atmos. and Oceanic Tech., 19, 2030-2048.

It uses the table provided by (in French): Collard, F., 2005, Algorithmes de vent et période moyenne des vagues JASON à base de réseaux de neurones, BO-021-CLS-0407-RF, Boost Technologies, 33pp.

For more information, see the Wave Along-track Level-2+ (L2P) page. The updated product handbook will be made available soon.
