Olga Wilhelmi – PI
Terri Betancourt – PI 2004
Jennifer Boehnert – UCAR GIS Coordinator
Integrates knowledge across disciplines and social groups
Promotes and supports the use of GIS as both an analysis and an infrastructure tool in atmospheric research and
Addresses broader issues of data management and geoinformatics within atmospheric and related geo- and social sciences

Technology
Leading atmospheric special interest group (>100 members from government, universities, the private sector)ADM - Community-based initiative and a working dialog between ESRI and atmospheric sciences community regarding atmospheric data representation and analysis challenges Conducted two data modeling workshops In process of developing a Conceptual Document (ArcGIS Atmospheric Data Model)Our collaboration with ESRI resulted in support for NetCDFfiles in ArcGIS
ADM Workshop 1 - Seattle, WA, January 16-17, 2004 at NOAA PMEL Lab
ADM Workshop 2 - San Diego, CA, January 14, 2005 at the Marriott Hotel & Marina

Main Gateway Objectives
Make communities aware of one another
Build standard interface to the many netCDF/OPeNDAP data servers already in operation
Allow traditional atmospheric data providers to migrate toward one standards-based service
Allow traditional GIS clients to access netCDF/OPeNDAP datasets via standards-based interface
Evaluate netCDF/OPeNDAP as WCS data transport (encoding) mechanism … suggest extension if warranted

Interactive Global and3D viewingOptimized to multi-scale viewingGreat for very large raster dataAlso support vector and 3D symbols
Multidimensional ArcGIS 9.2Extend existing functionality to support time and multidimensional data
Animation manager learns how to use a variable such as time to set the animation sequence.Improve quality and interaction of charting and include as an animation object.Add support for the NetCDF data format building on existing layer capabilities.
LinkingLinking
Select a feature in the map, record in the table, or element in the graph and see it highlighted in the other windows.
BrushingBrushing
Drag a selection box around features in the map, records in the table, or element in the graph and see it interactively highlighted in the other windows.
NetCDF in ArcGIS
NetCDF data can be accessed throughRasterFeatureTable
Direct Read – no scratch files
NetCDF Tools in ArcGISMake NetCDF Raster Layer

Select by Dimension
Using NetCDF Layer/Table
Behaves the same as any layer or table in:Display
• Same display tools for raster and feature layers will work on netCDF raster and netCDF feature layers.
Charting• Driven by the table just like any other chart.
Animation• Multidimensional data can be animated through a
dimension (e.g. time, pressure, elevation)Geoprocessing Tool
• A netCDF raster layer will work just like any other raster layer, same for feature layers and tables.
