This is a $75,000 grant awarded by the National Aeronautics and Space Administration (NASA) Shared Services Center to Panorama Pathways, a woman-owned small business, to continue operation of the Global Emissions Initiative (GEIA) website. GEIA is a major cross-cutting activity of the International Geosphere-Biosphere Programme that provides quality-assured emissions information for global assessments of atmospheric chemistry, air quality, and climate change. The grant will support key GEIA activities, including facilitating scientific working groups, expanding emissions datasets, and strengthening the emissions research community. This award contributes directly to NASA's science program objectives by making high-quality emissions data and related information readily available to researchers. The contract does not have a set-aside designation.

The global emissions initiative (geia) is a major crosscutting activity of the international geosphere-biosphere program (http://WWW.igbp.net/) that is linked to igac (http://WWW.igacproject.ORG/), ileaps (http://WWW.ileaps.ORG/), and aimes (https://ncar.ucar.EDU/integrated-science/analysis-integration-and-modeling-of-the-earthsystem- aimes). Since its inception in 1990, geia has been providing necessary, qualityassured emission information for comprehensive global assessments of past, present and future atmospheric chemistry, air quality and climate change. Through its ongoing initiatives, geia advances the development, evaluation, distribution and use of timely, critical emissions information. The NASA-sponsored geia web site (http://WWW.geiacenter.ORG) is geia s communications center and is managed by paulette middleton, working closely with the geia scientific steering committee chaired by greg frost and leonor tarrason. By the year 2020, geia aims to be a key forum dedicated to expanding emissions knowledge in a rapidly evolving society, by: 1) building the scientific basis of emissions understanding and facilitating analysis of emissions processes; 2) improving access to emissions information; and 3) strengthening the community of emissions groups involved in research, assessment, operations, regulation and policy. This proposal requests NASA funding to continue essential operation of the geia web site, the communications center for geia, including work in the following key activity areas: ??analysis. Providing a communications platform for geia scientific working groups that focus on specific emissions topics; facilitating on-line dialogues about new emission challenges; and working toward establishing a virtual clearinghouse of scientific emissions analysis, with the eventual goal of enabling the construction of inventory ensembles and the assimilation of observations for emissions evaluation and atmospheric forecasting. ??access. Expanding datasets available through geia s main data portal, emissions of atmospheric compounds and compilation of ancillary data (eccad) (http://pole-ether.FR/eccad); building a searchable bibliography for journal articles and reports on emissions; and collaborating on data interoperability to implement on-line visualization and evaluation tools, with the goal of creating a virtual workspace for emissions analysis and forecasting applications; ??community. Keeping geia network engaged through periodic email alerts on new information available on the web site and reminders to users to post information and join discussion forums; organizing and reporting on BI-annual geia conferences and other key meetings and educational events; and broadening the geia user base by providing information on the use of science in decision-making, and on best practices for emissions estimation and uses. The proposed project will contribute directly to NASA science program objectives by making the highest quality, up-to-date data and related information on emissions and land-water-air exchange processes readily available to researchers studying the distribution and behavior of trace constituents in the global troposphere and stratosphere.
