The objectives of the AIST program are to identify, develop and
(where appropriate) demonstrate advanced information system
Reduce the risk, cost, size, and development time of Earth
Science Division (ESD) space-based and ground-based information
Increase the accessibility and utility of science data, and
Enable new observation measurements and information products.
Multi-Sensor Data Synergy Advisor (MDSA)
Augment Giovanni, the Goddard online tool for data access, visualization and analysis, with semantic web technologies and ontologies to support data inter-comparisons from different sensors or models.
Data provenance (i.e. the essential data parameter details, quality and production caveats) will be added to enable researchers to make valid data comparisons and draw quantitative conclusions on specific analysis (e.g. ocean fertilization due to acid rain).
In the resulting Giovanni framework, the dataset variable characteristics and related quality can be encoded so that inter-comparison rules can be derived.
