Cold-water conditions off the western tropical coasts of the Americas, occurring irregularly and occasionally following El Ni\xf1o conditions, caused by stiffening trade winds and regenerated fisheries, drought in the central and eastern Pacific, and rain in the western Pacific.
Uses a laser that transmits short pulses of infrared light and/or visible light. Photons reflected back to the spacecraft from the surface of the Earth and from the atmosphere, including the inside of clouds, will be collected in a telescope. The height measurement from the altimeter to the ocean surface is useful in various oceanographic applications. Determination of sea surface topography is useful for marine gravity determinations, seafloor bathymetry estimations, and dynamic circulation of the oceans.
