Surge is a displacement along an axis that is perpendicular to the local vertical axis and is coplanar with the nominal forward motion direction of the platform. Surge is relative to the "at rest" position of the platform with respect to the axis of displacement. "Fore" indicates that positive values of surge represent the platform moving forward as viewed by an observer on top of the platform facing forward. The standard name platform_surge_aft should be used for data having the opposite sign convention. The standard name platform_surge should be chosen only if the sign convention of the data is unknown. A "platform" is a structure or vehicle that serves as a base for mounting sensors. Platforms include, but are not limited to, satellites, aeroplanes, ships, buoys, instruments, ground stations, and masts.
