Glaciers_cci is contributing to the efforts of creating a globally complete glacier inventory as requested in action T2.1 by GCOS (2006). This includes data creation (glacier outlines) in selected and key regions as well as establishing a more consistent framework for glacier identification to improve the consistency among the available datasets. The project is also deriving elevation changes and velocity fields from remote sensing data to complement the information on global glacier changes obtained in the field.

The cryosphere in high elevation regions is a very sensitive indicator of climate change and meltwater from the cryosphere is a significant fraction of fresh water resources in many parts of the world, particularly in China and in the countries receiving waters from the Tibetan Plateau. Cryosphere and hydrology questions should be linked towards better science on the terrestrial water cycle across a range of spatial and temporal scales. This leads to the need of connecting regional and global analyses of water resources. Fully integrated use of satellite, ground observations and hydrological distributed models is necessary to support water resources management and to clarify the roles of the interactions between the land surface and the atmosphere over the Tibetan Plateau in the Asian monsoon system.
This project is part of an integrated response to the Dragon 4 Theme “Hydrology & Cryosphere” with the projects "Multi – source hydrological data products to monitor High Asian River Basins and regional water security” (MUSYCADHARB led X. Li and M. Menenti) and “Earth Observations tools for Water resource and quality monitoring in Yangtze wetlands" (EOWAQYWET, Y. Wang and H. Yesou).
Within this subproject will generate an (rock)glacier inventory and assess both area and volume changes for benchmark regions in High Mountain Asia (HMA) taking advantage of the synergies of European and Chinese optical and microwave space-borne observation systems.
Similar advantage will be taken
- to investigate the flow velocity of (rock)glaciers and their changes over time,
- to map snow cover and their evolution,
- to map permafrost and its evolution and assess the possibilities to map and monitor the active layer.
- We will assess temporal and regional trends of glacier elevation changes of entire HMA by altimetry missions.
- The generated data will be instrumental for forcing, calibration, validation and data assimilation in basin scale glacio-hydrological models.
