  2. LONG-TERM GUIDING GOAL To understand and model the influence of continental hydroclimate processes on the predictability of global atmospheric circulation and changes in water resources, with a particular focus on the heat source and sink regions that drive and modify the climate system and anomalies. • Integrated global dataset: • in-situ observation (35 reference sites) • satellite products • model output c Coordinated in time and space; Consistent format compatible with ISO standards; Good accessibility

  8. Possible Steps for Expanding the CEOP System to Accommodate Cryosphere Data and Products • To include into the CEOP database observations from existing reference sites/basins in cold regions (Arctic/Antarctic) • To include further cryosphere satellite products into the CEOP database • To include cryosphere-related model output into the CEOP database; identify further variables (if any) that need to be stored • To accommodate “special-format” cryosphere data and products (glaciers, permafrost, sea ice…) – need to discuss with the data management group the format and the way how to include these types of data  workshop

  9. CEOP-CliC Collaboration • CEOP Phase 2 – Cold region study:To diagnose, simulate and predict water and energy fluxes and reservoirs in cold regions on diurnal to annual temporal scales as well as apply these predictions for water resource applications based on the enhanced observations and the tools and techniques already established by CliC and CEOP. • CEOP-CliC proposal for IPY: • Convergence of Observation and Data Integration (Reference site/basin network in cryosphere; Integrated satellite products in cold region) • Long-term Variation of Snow Distribution in the Northern High Latitude Region and Its Impacts on Atmospheric Circulation (Seasonal and Inter-annual Variation of Land Hydrological Conditions – using satellite products validated by in-situ observations) • Water and Energy Budgets (WEBs) (Whatcomponents of the water and energy cycles in northern latitudes can be observed, and how well they can be simulated;Impactsof the WEB variation on the atmospheric circulation;Intercomparison among the large river basins facing to Arctic Sea) • High Mountain Hydrology Including Glacier (From process study to application to water resources management)

  10. 1. Convergence of Observation and Data Integration • Targets: • ・Reference site/basin network in cryosphere • ・Integrated satellite products in cold region • Strategy: • (1) Sophistically integrated in-situ observation (super site/basin) including isotope, streamflow: new site involvement through focusing location, number, standard. • (2) Common metadata and data policy (Interoperability) (ISO19115; Link CEOP Data to DISC; Shared Archives, Buoys, field project data, Satellite data/products) • (3) Data quality check (CEOP standards; Solid precipitation questionnaire for reference sites) • (4) Integrated satellite products validated by in-situ data: snow, snowfall, soil moisture, canopy snow, (vegetation) • (5) Precipitation data applying various methods

  15. CEOP Reference Sites Data Release Guidelines CEOP Reference Site Data Categories: Standard Data (Category 1):Common or low exploitation value, measurement technology common, generally well understood. Enhanced or Experimental Data (Category 2):High exploitation value, measurement technology sophisticated and/or of experimental nature, contact to PIs highly recommended. Data providers decide on category division of their data !
