The Information System and Data Center (ISDC) is an access point for diverse geoscientific data, corresponding metadata, scientific documentation and software tools. The majority of the data and information that are offered to the public are global geomonitoring products such as satellite orbits (e.g. of Low Earth Orbiters) or Earth gravity field models (e.g. derived from GRACE or GRACE-FO mission data), Earth System Modelling data (e.g. the Atmosphere and Ocean De-aliasing Product) as well as various geomagnetic and atmospheric data. The design of the ISDC portal and its operation is a project of the ISDCteam within GFZ's “IT Services and Operations” section together with GFZ's sections 1.2 "Global Geomonitoring and Gravity Field", 1.3 "Earth System Modelling" and 2.3 "Geomagnetism".

We invite you to use our services and they will benefit your scientific work.
