Summary
Abstract: More Information: http://www-pcmdi.llnl.gov/software-portal/cdat

Climate Data Analysis Tools (CDAT) is a software infrastructure that uses an
object-oriented scripting language to link together separate software
subsystems and packages thus forming an integrated environment for solving
model diagnosis problems. The power of the system comes from Python and its
ability to seamlessly interconnect software. Python provides a general purpose
and full-featured scripting language with a variety of user interfaces
including command-line interaction, stand-alone scripts (applications) and
graphical user interfaces (GUI). The CDAT subsystems, implemented as modules,
provide access to and management of gridded data (Climate Data Management
System or CDMS); large-array numerical operations (Numerical Python); and
visualization (Visualization and Control System or VCS).

One of the most difficult challenges facing climate researchers today is the
cataloging and analysis of massive amounts of multi-dimensional global
atmospheric and oceanic model data. To reduce the labor intensive and
time-consuming process of data management, retrieval, and analysis, PCMDI and
other DOE sites have come together to develop intelligent filing system and
data management software for the linking of storage devices located throughout
the United States and the international climate research community. This
effort, headed by PCMDI, NCAR, and ANL will allow users anywhere to remotely
access this distributed multi-petabyte archive and perform analysis. PCMDI's
CDAT is an innovative system that supports exploration and visualization of
climate scientific data sets. As an "open system", the software sub-systems
(i.e., modules) are independent and freely available to the global climate
community. CDAT is easily extended to include new modules and as a result of
its flexibility, PCMDI has integrated other popular software components, such
as: the popular Live Access Server (LAS) and the Distributed Oceanographic Data
System (DODS). Together with ANL's Globus middleware software, CDAT's focus is
to allow climate researchers the ability to access and analyze
multi-dimensional distributed climate data sets.
