// REANALYSIS ENSEMBLE SERVICE (RES)
MERRA ANALYTICS INTERFACE
The Reanalysis Ensemble Service (RES) allows users to perform queries on reanalysis datasets from MERRA data. RES was created to address the Big Data challenges of climate science. As the availability and volume of Earth data grow, researchers spend more time downloading and processing their data than doing science. The NASA Center for Climate Simulation (NCCS) has developed the Reanalysis Ensemble Service (RES), a high-performance big data analytics framework built on Apache Hadoop, to allow researchers to leverage our compute power to analyze large datasets located at the NCCS through a web-based interface, thereby eliminating the need to download the data.
RES provides access to a suite of “canonical operations”—min, max, sum, difference, average, root mean square, anomaly, and standard deviation— that researchers can combine to develop various workflows. RES uses MapReduce to efficiently processing huge datasets within limited memory spaces at interactive and batch response times. These operations and datasets can be accessed via RES using applications written by the user.
The RES interface supports web service access to consumer applications, a graphical user interface for interactive requests, a command line interface for users familiar with basic RES commands, and advanced programmatic access for Python-savvy users. RES allows users to compute close to the data without downloading input datasets.
