Dear all, I would like to request the creation of new standard names for the local geographic components of the platform_speed_wrt_ground.
Following the already existing definition of speed, velocity, and the naming scheme for the wind component (eastward_wind, northward_wind, upward_air_velocity), I propose : - platform_northward_velocity_wrt_ground "wrt" means with respect to. Standard names for platform describe the motion and orientation of the vehicle from which observations are made e.g. aeroplane or ship. A velocity is a vector quantity. The platform velocity with respect to ground is relative to the solid Earth beneath it i.e. the sea floor for a ship. It is often called the "ground speed" of the platform. "Northward" indicates a vector component which is positive when directed northward (negative southward). Platform_northward_velocity_wrt_ground is the northward component of the 3D platform velocity vector. - platform_eastward_velocity_wrt_ground "wrt" means with respect to. Standard names for platform describe the motion and orientation of the vehicle from which observations are made e.g. aeroplane or ship. A velocity is a vector quantity. The platform velocity with respect to ground is relative to the solid Earth beneath it i.e. the sea floor for a ship. It is often called the "ground speed" of the platform. "Eastward" indicates a vector component which is positive when directed eastward (negative westward). Platform_upward_velocity_wrt_ground is the eastward component of the 3D platform velocity vector. - platform_upward_velocity_wrt_ground "wrt" means with respect to. Standard names for platform describe the motion and orientation of the vehicle from which observations are made e.g. aeroplane or ship. A velocity is a vector quantity. The platform velocity with respect to ground is relative to the solid Earth beneath it i.e. the sea floor for a ship. It is often called the "ground speed" of the platform. "Upward" indicates a vector component which is positive when directed upward (negative downward). Platform_upward_velocity_wrt_ground is the vertical component of the 3D platform velocity vector.
