... There are 13 discipline-based World Data Centers in the United States, including centers for atmospheric trace gases, glaciology, human interactions in the environment, marine geology and geophysics, meteorology, oceanography, paleoclimatology, remotely sensed land data, rockets and satellites, rotation of the Earth, seismology, solar-terrestrial physics, and solid Earth geophysics. In addition to these World Data Centers, federal science agencies maintain nine national data centers, which provide access to an array of publicly available datasets.

... The Land Processes Data Center evolved out of the USGS EROS Data Center, created for long-term data storage in 1972 to archive, process, and distribute Landsat data. These DMCs are among 16 major data archives, data centers, and services that disseminate NASA's Earth Science and Space Science Enterprise data (NRC, 2002~.
