CEOP AEGIS

Hydrology and Climatology of South and

East Asia

EU GEO project

Li Jia – WUR Alterra NL

Jerome Colin – Univ. Strasbourg F

18 beneficiaries from 8 european and asian countries

An international cooperation project between Europe and Asia to improve knowledge on hydrology and meteorology of the Tibetan Plateau and its role in climate, monsoon and extreme meteorological events To construct out of existing ground measurements and

current / future satellites an observing system to determine and monitor the water yield of the Plateau, i.e. how much water is finally going into the seven major rivers of SE Asia

To monitor the evolution of snow, vegetation cover, surface wetness and surface fluxes and analyze the linkage with convective activity, (extreme) precipitation events and the Asian Monsoon.

ID-03 Science and Technology in GEOSS

Activities:

1.1 Develop a framework for the transition of relevant research infrastructures to

sustained operation

1.2 Encourage the incorporation of new technology in observing systems

1.3 Assess the requirement for continuity and long-term monitoring by Earth

observation systems of essential data from GEOSS components.

1.4 Support state-of-the-art technology in the GEOSS Common Infrastructure (GCI)

and observation infrastructures

Data system operational at Institute Tibetan Plateau Research,

Beijing

New algorithms developed and applied for several hydrological

observations

Most hydrological data sets 2008 – 2010 produced and available

on data system

Distributed hydrological model Plateau and headwaters main

rivers S and E Asia developed, evaluation in progress

Trans-boundary water transfers downstream of Plateau evaluated

(Bangladesh, India, Pakistan..)

125 team Members

79 MSc and 93 PhD students active in the framework of the project

CEOP-AEGIS

Achievements

Stakeholders Meetings and training sessions in China, India and

Nepal

Consolidation / full fruition of results requires a follow-up phase of

at least 3 years

Dual fruition:

Transfer of knowledge and methods to other parts of the world

Demonstration case-studies to include complete river basins

around the Qinghai – Tibet Plateau

CEOP-AEGIS

Suggested priorities

Basic data to monitor fresh water resources world-wide: increasingly scarce,

hard to access data on river flows

Hydrological data products + integration by large area hydrological models

Expand current data base of water level in lakes and rivers merging all laser

and radar altimeter data

Integrate water quantity and water quality information for a few exemplary

large transnational watersheds to document benefits of shared hydrologic

information
