PRAISE: a new research groupPRAISE
Progressive Research on Atmosphere-Biosphere-Hydrosphere and their Interaction in Semi-Arid Northeast Asia (tentative)
Targeted area: Eastern MongoliaScientific foci
Land-atm. interactionInterannual & interseasonal variability of rainfall
Coordination & Cooperationwith Inst. Met. & Hydro., Mongoliawork as NE Asia regional group of MAHASRIwith CEOP, as a ref. sites and as semi-arid groupwith Asia flux (as a registered sites)with MAIRS arid/semi-arid groupwith UNESCO-IHP groundwater program.

Background: Vegetation (USGS-GLCC)
Contour: Precipitation (CMAP,1979-2006, mm/year)
Gobi & Desert
Taiga Forest
Grassland
Intensive Obs. Regionmainly steppe grassland and taiga forest
Strong N-S gradient of precipitation and vegetation.
=> strong temporal variability of the land cover.

25year annual mean recycling ration at 105 km2 (Dirmeyer & Brubaker, 2007)
Annual Mean Recycling Ratio
Fairly larger recycling ratio

Contribution to AMY 08
Observations & Data2 full surface flux sites (grassland, forest) in eastern Mongolia:
as CEOP2-reference sites & AsiaFlux sites
4 AWSs (rain, temp., wind speed, soil, etc.)
Research TargetsLand-atmosphere interaction:
especially, its biospheric and soil-moisture aspects.atmosphere -> biosphere: intercomparison with other AsiaFlux sites all over Asia.biosphere (esp. dyn. vegetation) <-> atmosphere: using LSMs
Interannual variability of precipitation and the monsoon.
