CEOS Water Portal CEOS Water Portal Status Update p Satoko Horiyama MIURA / Atsushi KAWAI JAXA/Mission Operations System Office
Introduction Introduction CEOS Water Portal is ; CEOS Water Portal is ; A web based portal system evolved from ”Distributed Data Integration System Prototype for CEOP” D t I t ti S t P t t f CEOP” To provide access to a whole variety of hydrological data and water relevant data scattered over the world To retrieve data from distributed data centers on ‐ the ‐ fly (by OPeNDAP etc.) and let users download and see rendered image/plot The Portal is NOT a system for data distribution. The Portal is aimed to become a system that enables data The Portal is aimed to become a system that enables data integration. 1
Concept Concept Data Integration g Multiple types of data are available such as; In ‐ situ data Satellite data Model output data The portal provides multiple functionalities and services Th t l id lti l f ti liti d i to perform data integration. Portal System Concept Provide users “Easy to Access” service. Provide users Easy to Access service. Users include; Scientists in hydrological domain y g Non ‐ researchers or operational users who are dealing with 2 those data in their work
Main Features of the Portal Main Features of the Portal Data Integration (1) Data Archive Centers in remote locations are connected (in-situ, satellite, and model using standard data access protocol (OPeNDAP) output) (2) Single user interface - Spatial Data Integration - Temporal Data Integration - Temporal Data Integration - Consistent data variable names Functions to facilitate Easy (1) Different types of search features : Category and Map Access (2) Select data by (2) Select data by - time range (start time / stop time) - CEOP Reference Site, Station name - height or depth - variable name (3) View data (gif image) (4) Compare MOLTS data and In-situ Data in a single chart (5) Download data (NetCDF ascii Grib (only Model output)) (5) Download data (NetCDF, ascii, Grib (only Model output)) Function to encourage (1) Users can register/upload their research results obtained by using communication among portal’s data, which then becomes available for other users to users (under development) reference at their data search on the portal. 3

Future Plan Future Plan Contribution to GEO Work plan (2009 ‐ 2011) Task WA ‐ 08 ‐ 01 (already offered to k l ( ) k ( l d ff d CEO) Work plan (2012 ‐ 2015 Version0 Under Technical Review) Work plan (2012 ‐ 2015, Version0, Under Technical Review) Task DS ‐ 05 New Data vs New Functions We are open to new data center collaboration (within budget !). The balance to be considered, based on the coordination Th b l b id d b d h di i with data center collaboration “candidates”. Adding the new function for more integrating the data Adding the new function for more integrating the data and encouraging the communication among the users. Collaboration with other “portal(s)”.
