Improvements to the Crustal Dynamics Data Information System
Abstract
NASA's space geodesy archive, the Crustal Dynamics Data Information System (CDDIS), provides data archiving and distribution support to a global research community. The archive consists of GNSS, laser ranging, VLBI, and DORIS data sets and products derived from these data. The CDDIS is one of NASA's Earth Observing System Data and Information System (EOSDIS) distributed data centers; EOSDIS data centers serve a diverse user community and are tasked to provide facilities to search and access science data and products. The CDDIS data system and its archive are vital components to many national and international science communities, in particular several of the operational services within the International Association of Geodesy (IAG) and its project the Global Geodetic Observing System (GGOS), including the International DORIS Service (IDS), the International GNSS Service (IGS), the International Laser Ranging Service (ILRS), the International VLBI Service for Geodesy and Astrometry (IVS), and the International Earth Rotation Service (IERS). Several activities are nearing completion at the CDDIS to aid users in data discovery, both within the international space geodesy community and beyond. The CDDIS has completed enhancements to its implementation of the Geodetic Seamless Archive Centers (GSAC). The service provides web services to facilitate data discovery within and across participating archives. The CDDIS is currently implementing modifications to the metadata extracted from incoming data and product files pushed to its archive to permit information about CDDIS archive holdings to be made available through other data portals such as Earth Observing System (EOS) Clearinghouse (ECHO). The CDDIS hopes to soon install an Ntrip broadcast relay to support the activities of the IGS Real-Time Pilot Project (RTPP) and the future Real-Time IGS Service. This poster will include background information about the system and its user communities, archive contents and updates, enhancements for data discovery, new system architecture, and future plans.
