Standard names for platform describe the motion and orientation of the vehicle from which observations are made e.g. aeroplane, ship or satellite. The platform vertical speed is the rate of change of platform altitude. "Upward" indicates a vector component which is positive when directed upward (negative downward). Speed is the magnitude of velocity. sea_level means mean sea level, which is close to the geoid in sea areas.

GRIB:

The platform vertical speed is the rate of change of platform altitude. "Upward" indicates a vector component which is positive when directed upward (negative downward). Speed is the magnitude of velocity. Platforms include, but are not limited to, satellites, aeroplanes, ships, buoys, instruments, ground stations, and masts. The abbreviation "wrt" means "with respect to".
