Earth Monitoring

The Gravity Recovery and Climate Experiment (GRACE) mission is a joint effort between the United States and Germany to provide monthly determinations of the Earth's gravity field with unprecedented accuracy. To date, the GRACE project has generated more than 120 terabytes of information files related to the Earth's atmosphere, ocean and land interactions. Corral is critical in supporting the GRACE mission's numerous data applications, enabling access and manipulation of this substantial dataset.

A map of the global gravity anomalies determined by with the GRACE measurements. The continental plate boundaries, the mid-Atlantic ridge and the hot spot that has created the Hawaiian island chain are some of the features identified in the map. The REDS represent mass excess relate to the local average and the BLUES represent mass deficiency.

"Timely access to high performance computing is a necessary capability for satisfying the GRACE Mission. Extensive data storage and access along with a large number of computational cycles and a short wall clock time are the demands placed on the computational support facility. To date, the GRACE project has generated more than 120 terabytes of information files, and live access to this substantial data set has been critical to support the numerous applications of the data. This data set is expected to continue to grow as new data is collected and additional experiments to improve the science data products are conducted."
