description: "The TOPEX/Poseidon microwave radiometer was a three-frequency sensor used to estimate the atmospheric water vapor content in the nadir column through which the altimeter signal is traveling. Since water vapor distorts the altimeter's reading, the water vapor content is measured to correct the altimetry measurement. The sensor uses one frequency to make the measurement, and two frequencies to remove the effects of wind speed and cloud cover. There is a backup receiver for the measurement frequency.\n"

  - description: "TOPEX/Poseidon (or simply T/P) is a cooperative Earth observation mission of the USA and France (NASA/JPL and CNES as partners) with the overall objective to provide high-accuracy global sea level (ocean height) measurements in coordinates relative to the center of the Earth. From this information, ocean circulation patterns can be mapped. The T/P data analysis helps to understand how the oceans interact with the atmosphere, and improve our ability to predict the global climate. NASA provided the satellite bus, five instruments, and is responsible for spacecraft operations. CNES furnished two of the spacecraft's instruments and the mission's Ariane launch vehicle."
