The latest addition to NASA’s Science Data website is access to the astronomy and geodesy database (AstroGeo). Geodesy refers to the use of astronomical techniques to measure the position of Earth in 3D space, as well as its gravitational field and shape. The discipline helps scientists to better understand processes such as plate tectonics, ocean tides, the atmosphere, and the motion of Earth’s poles.

NASA’s AstroGeo data products include tools to measure mass loading on Earth’s crust, Earth’s atmospheric conditions, and the Earth orientation parameters (EOP) that describe irregularities in the planet’s rotation. To explore these and other AstroGeo data products, visit the new AstroGeo page.
