Climate Research in Hawaii:
International Pacific Research Center
IPRC MissionIPRC MissionTo provide an international, state-of-the-art research environment to improve understanding of the nature and predictability of climate variability in the Asia-Pacific sector, including regional aspects of global environmental change
1995–1997: Plans for the IPRC were developed by scientists from Japan, the University of Hawaii, and an external group of climate scientists and administrators.
March, 1997: Japanese Prime Minister Hashimoto and US Vice-President Gore add the theme of global change research and prediction to the “Common Agenda for Cooperation in Global Perspective.” Japan and the US formally agree to establish the IPRC.
October, 1997: Japan initiates the Frontier Research System for Global Change (FRSGC).
October, 1997: IPRC is founded within the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaii at Manoa, as one of the 8 divisions of FRSGC.
IPRC BackgroundIPRC Background
Existing infrastructure
• Institutional support from JAMSTEC, NASA, and NOAA provides the funding necessary for long-term stability and planning.
• The University of Hawaii established 10 tenure-track faculty positions, jointly funded by the state of Hawaii and JAMSTEC. These positions are the scientific core of the IPRC.
• The APDRC is now able to deliver the model-based and satellite-based products to the broad user communities via web-based access.
Links with Asia
• The IPRC has strong links with JAMSTEC scientists and with the Japanese scientific community in general.
• The IPRC has established research collaborations with the Earth Simulator Center. We are part of a consortium to analyze output from AGCM and OGCM runs with unprecedented spatial resolution, and are involved in discussions with our Japanese colleagues on future numerical experimentation.
• IPRC researchers also have working relationships with scientists in China and Korea
IPRC Science ThemesIPRC Science Themes

Global impacts of volcanismRegional response to global climate forcingAnalysis of coupled models of global changePaleoclimate variability
The APDRC was established within the IPRC to be a climate data and web-based product serving facility. Our mission is to increase understanding of climate variability in the Asia-Pacific region by:
• developing the computational, data-management, and networking infrastructure necessary to make data resources readily accessible and usable by researchers and other users;
• undertaking data-intensive research activities that will both advance knowledge and lead to improvements in data collection and preparation.
Challenges for Distribution of Climate Data
● disparate data types– station data, gridded data, ocean data,
atmospheric data, levels, time-series, etc.● disparate data formats
– netcdf, grib, flat binary, etc. ● datasets can be large
– coupled model out, long integrations, high resolution (time/space), etc.
● users needs are widely varying
Data Transport
● ftp (limited)● direct binary access NFS (internal)● OPeNDAP
On-line Browse
● LAS (gridded data)● EPIC (station data)

THREDDS functions that matter to APDRC
• An integrated server provides OpenDAP access to any datasets that can be read through the Netcdf-Java library.
• The Netcdf-Java library reads NetCDF, OpenDAP, and HDF5 datasets, as well as other binary formats such as GRIB and NEXRAD into a "Common Data Model" (CDM).
• An integrated server provides data access through the OpenGIS Consortium (OGC) Web Coverage Service (WCS) protocol for any "gridded" dataset whose coordinate system information is complete. Users can add missing information to a dataset where needed, in order to make this work.

GODAE
As the international community participates in the demonstration phase of GODAE,
(2003-2005)there is an overarching need for rapid delivery of
data products from satellites and models to the broad user community including regional
operational entities.
