Advanced Information Systems Technology (AIST)

Objectives
The objectives of the AIST program are to identify, develop and (where appropriate) demonstrate advanced information system technologies which:

• Reduce the risk, cost, size, and development time of Earth Science Division (ESD) space-based and ground-based information systems,
• Increase the accessibility and utility of science data, and
• Enable new observation measurements and information products.

Technology Drivers
The AIST Program is founded on technology needs for Earth science measurement, analysis, and application objectives. In 1999, ESTO sponsored a Request for Information and workshop involving the Earth and information science communities to help guide the definition of technology needs which resulted in the AIST Capabilities and Needs (CN) Database. The CN Database is referenced in AIST technology solicitations. In 2000, ESTO sponsored a technology projection workshop that assessed emerging information technology for space and ground use that resulted in the AIST Key Space and Ground Investment Roadmaps. In early 2002, another technology projection workshop was held to further refine and update the AIST Capability and Needs database as well as the Key Investment Themes (this 2002 version of the CN Database is available here, the current version is linked below). The roadmaps, coupled with analysis of nominal future Earth science scenarios, are used to provide weighting criteria for the CN Database, which is then refined to guide future NRA and other solicitations for technology development. In 2008, the goals and needs were updated and reviewed by members of the Earth science information systems community:

Several other initiatives and programs within ESD provide technology drivers to the AIST Program. These include the current Earth Observing System Data and Information System (EOSDIS), the Earth Science Mission Operations (ESMO), the Instrument Incubator Program (IIP), the Computational Technologies (CT), the Earth Science Applied Science Program, the Earth Science Information Partners (ESIP Federation) and NASA's Earth Science Data System Working Groups (ESDSWG). The long-term goals of the ESD science focus areas also present significant technology challenges for information systems. Based on a cyclic analysis of technology need, AIST identifies and prioritizes ESD information technology goals.

Technology Infusion Opportunities
Many technology infusion candidates are targeted for AIST developments. ESD roadmapping activities are identifying science objectives, missions, and some technology drivers. This information is being expanded with insights on new missions, some currently in formulation, such as NPOES Preparatory Program (NPP), Global Precipitation Measurement Mission (GPM), Landsat Data Continuity Mission (LDCM), and others. ESTO is especially interested in addressing the recommendations of the National Research Council’s Earth Science and Applications from Space: National Imperatives for the Next Decade and Beyond, know as the “decadal survey”. Other initiatives and programs within ESD include EOSDIS , the ESIP Federation , the Earth Science Mission Operations (ESMO), and the Earth Science Data Systems Working Groups.
