Part of the Earth Observing System Data Information System, the Physical Oceanography Distributed Active Archive Center is responsible for archiving and distributing data relevant to the physical state of the ocean. The data, which are intended for use in oceanographic and other interdisciplinary scientific research, is freely available. Products include sea surface height, ocean wind, and sea surface temperature data. Recently added datasets include BYU High Resolution Images of ERS Sigma0 Measurements and ATSR-2 Gridded Brightness Temperature.
