CDDIS as part of EOSDIS receives the 2015 Pecora Award

William T Pecora Award Certificate for 2015 for the NASA CDDIS

EOSDIS was awarded the 2015 Pecora award. This prestigious William T. Pecora award is given to groups that make outstanding contributions toward understanding the Earth by means of remote sensing. The citation highlights the EOSDIS accomplishments in providing an open archive system for a global user community.

CDDIS is one of twelve DAACs supporting EOSDIS efforts through the Earth Science Data and Information System (ESDIS) project. Carey Noll , CDDIS Manager, accepted their award certificate from Andy Mitchell, ESDIS Project Manager, and Jeanne Behnke, Deputy Project Manager/Operations, at the February 2018 EOSDIS Distributed Active Archive Center (DAAC) Managers Meeting, at Oak Ridge National Laboratory, Tennessee.

Note from the Director:
I would like to thank the Director’s Science Committee for putting on an amazingly successful event where scientists and engineers across Goddard shared their work and made new contacts. The interdisciplinary interactions were especially exciting and crossed all four science disciplines.

The NASA CDDIS has another year of record growth in 2017


The Crustal Dynamics Data Information System (CDDIS) had another year of record growth with 1.7B file downloads (206TB) of data transferred to over 260K unique users in 2017. EOSDIS (Earth Observing System Data and Information System) reports that CDDIS led the twelve Distributed Active Archive (DAACs) in the number of files downloaded last year. Furthermore, CDDIS GNSS (Global Navigation Satellite System) data/products accounted for three of the top data sets distributed by EOSDIS.

- The CDDIS now provides GNSS real-time streams from over 330 global sites as well as nearly 40 real-time product streams to the public through the NTRIP (Networked Transport of RTCM via Internet Protocol) real-time caster. These data streams include 38 NASA GDGPS (Global Differential GPS) sites as well as 31 sites provided by the University of Chile for testing in support of the READI (Real-time Earthquake Analysis for Disaster Mitigation) initiative.

- In December 2016, CDDIS installed an extensive system upgrade using virtual machine architecture for reliability and expandability, providing better infrastructure (power, network connectivity) and increased storage capability. A streamlined archive operations architecture and data upload process were also implemented.

The laboratory performs broad research, in the areas of Earth time variable and static geopotential and geomagnetic fields, Earth orientation, surface deformation, characterization and change, tides, land ice mass evolution, global and regional sea level, and airborne and spaceborne laser altimetry. The laboratory also supports many NASA missions in fundamental and core capabilities including satellite radar and laser altimetry precise positioning, pointing, ranging, timing, geolocation and calibration and validation. The laboratory is a leader in the design, development, implementation and application of airborne and spaceborne geodetic laser altimeter technology and instruments including NASA’s Land, Vegetation, and Ice Sensor (LVIS) and the Global Ecosystem Dynamics Investigation Lidar (GEDI). The laboratory is the home of the Space Geodesy Project which encompasses the management, development, operation and maintenance of NASA’s Space Geodetic Network that is comprised of the four major space geodetic observing systems: Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Navigation Satellite System (GNSS), and the Doppler Orbitography and Radio-positioning by integrated Satellite (DORIS) system. It is also home to the Crustal Dynamics Data Information System dedicated to the archive and distribution of space geodesy related data sets; as well as the home to GEODYN, NASA’s state-of-the-art geodetic parameter estimation and precision orbit determination system.
