Goals: Promote and support the
use of GIS as an analysis and infrastructure tool in -atmospheric
research; address broader issues of spatial data management,
interoperability, and geoinformatics; help integrate NCAR data
and knowledge across disciplines andsocial groups.
• To what extent can the emerging GIS
interoperability standards address NCAR’s legacy data
and information systems integration issues?
• Can we articulate abstract requirements for representing
and querying time-dependent,real-time, and volumetric data?
• What are the needs of the GIS user
community for weather and climate data and information?
• What are the metrics for evaluating
the practical limits of general-purpose GIS and relational database
technology in atmospheric research?
• Can we develop an atmospheric data
model that is general enough to be flexible and specific enough
to be useful?
• A community workshop in August 2002
brought more than 70 participants from academia, government,
and the private sector to discuss potential GIS-related research
• An in-house lecture series now encourages
the use of GIS at NCAR and UCAR through training and education.
• This year the initiative has partnered
with GIS technology leaders in the public realm (the OpenGIS
Consortium, or OGC) and the private sector (Environmental Systems
Research Institute, or ESRI). NCAR is participating in the OpenGIS
Consortium conformance and Interoperability Test and Evaluation
(CITE) project. The initiative is working with ESRI to develop
an atmospheric data model, similar to those developed for hydrological
and oceanographic communities, that will provide a structure
for seamless integration of atmospheric data in GIS.
• Through an NSF grant, a demonstration
project explored both commercial and open-source approaches
to spatial data from the International H2O Project.
• A special session at April’s
joint EGS-AGU-EUG conference in Nice included nearly 30 papers
and posters on the use of GIS in meteorology and climatology

information systems in weather, climate, and impacts. Bulletin

Coming up: A key research area
is the compatibility of weather and climate data with GIS-based
formats. NCAR implementation of OpenGIS and the development
of the atmospheric data model will continue, as well as the
expansion of the GIS community in the -atmospheric -sciences
through conferences and meetings (including a second community
workshop at NCAR next summer).
