Status of JAXA system
1. Introduction1.1 What is “JAXA Distributed Data Integration System” ?
10
1) Originally developed for CEOP project (CEOP : Coordinated Energy and Water Cycle Observations Project http://www.ceop.net/)
2) The system (aka WTF-CEOP system, http://jaxa.ceos.org/wtf_ceop/) is developed aiming to integrate various CEOP data stored in “distributed” data centers, where such system architectures as examined in CEOS/WGISS is applied.
1.2 Feature of CEOP Data and Distribution of CEOP Reference Sites
11Phase II period (2007-2011) : 52 CEOP Reference Sites
Phase I period (2002-2004) : 35 CEOP Reference Sites
[Data Type] - In-situ data, - Satellite data, - Model output
(1) Major Feature of CEOP Data
(2) Global Distribution of CEOP Reference Sites
[Location] - CEOP Reference Sites
[Period] - Phase I : 2002 - 2004, - Phase II : 2007 - 2011

1.4 System Summary of JAXA Distributed Data Integration SystemData Integration (in-situ, satellite, and model output)
(1) CEOP Archive Centers in remote locations are connected using standard data access protocol : --OPeNDAP(2) Single user interface - Spatial Data Integration - Temporal Data Integration - Consistent data variable names
Functions to facilitate Easy Access
(1) Select Data by - time range (start time / stop time) - CEOP Reference Site, Station name - height or depth - variable name(2) View data (plot and view values on the screen) (3) Compare Model output data and In-situ Data in a single chart(4) Download data (NetCDF, ascii)

2. Status and User Requests
14
(2) Users Requests• Enhancement of current data services is requested from users towards
comprehensive hydrological data service for water community.
(1) Status
• We would like to enhance both Data and Services of the JAXA Distributed Data Integration System as a portal for water community.
• The system has been operational for five years. • CEOP phase I data (2004-2004) can be accessed via the system.• CEOP phase II data (2007- ) will be incorporated in this year.
- Precipitation- Run off/River discharge- Groundwater- Flux
Requested Hydrological Data: GTN-H data
3.1 Various Hydrological Data
15< Station Map of GRDC/GTN-R >
< GPCC Monthly Precipitation Data >
< IGRAC Groundwater Map >
3.2 Requested Data from Users
16
Primary target data in this current first phase.
• Very important and essential, but missing in the current system.
One of Requested Data for Hydrological Application = River Basin Data
Requested data are sumarized

5. User Service Concept of the New System5.1 User Service Concept
In order to achieve quick and smooth “find and view” of various hydrological data, some key points were identified and reflected into the User Interface plan.
• GUI Plan for users to Select and Access Easily
- Data Type (Grid, Location Time Series)- Hydrological Variables (Precipitation, river discharge, groundwater, flux ..)- Time Range, Observation Interval- Space Range - Format
• Portal are to be capable of handling various datasets and adding more datasets flexibly afterward.<Various Datasets>
22
5. User Service Concept of the New System(Cont’)• GUI Plan and identified Key Points
GUI Plan Key Points
(A) Dataset Selection Page -Available Dataset is easy to select, by Water Cycle categories and/or by map.
(B) Dataset Information Page - Dataset information is given to understand dataset.
(C)
Data Parameter Selection Page -
Dataset parameters (hydrological variables, period, area, etc) are clearly given to identify data granule easily.
- Within several simple steps, selection can be made.
(D) Data View Page - Data can be viewed in Web Map and Graph.
- River Basin information is available in the map and data selection.
- Easy to access another related data sequentially.

5. User Service Concept of the Water CoP Portal (Cont’)5.2 User Interface and Use Case Example
Select/Zoom in to certain region/river basin
(3) Select dataset, select parameter, then view/obtain each data
(e.g. using station maps of CEOP, AWCI, GRDC, and so on)
(e.g. referencing GRDC Basins GIS Data)
(e.g. using GPCC data)
(2) View available images and In-situ stations’ location
• Detail of services is under examination from the viewpoint that how they will be realized in GUI.
Sample Use Case and GUI under development “See precipitation image first, next, select river basin, then view multiple hydrological variable data plots in that basin to think about water flow.“
(1) View precipitation image
… Following slides show parts of GUI.

5.2 Use Case Example
Select/Zoom in certain region (or river basin) in the Web Map.
(1) View precipitation image, at the “(A) Dataset Selection Page”
View image in the Web Map.

5.2 Use Case Example (Cont’)(2)View available images and In-situ stations’ location, “(A) Dataset Selection Page”
(e.g. using GRDC Basins GIS Data, station location info of CEOP, GRDC, and so on)
Available datasets and their location info come up in the Web Map and Menu. Station info appears which may has
a link to a profile of that station.
