A Climate Data Portal
Overview

Objective:


Unified, networked access to geographically distributed data from
Observing Systems and Historical Data Archives (focus on in situ data)
Method:

Integrate several new, modern and proven, off-the-shelf network-based
applications and technology developments


Sophisticated Java tools



Open Source Java, CORBA, LDAP, XML
Free and low maintenance
Extensible




From a desktop Java application or the web
Modern, scalable off-the-shelf components


for subsetting large, irregular, in situ data collections
Data fusion and data download


to distributed observational datasets
Scalable
Extensible to satellite, gridded products, model results
Poised to utilize new networking technology (e.g.,network Quality
of Service, Collaboration)
Significant technology spin-offs already realized
