RAISE (Rangelands Atmosphere-Hydrosphere-Biosphere Interaction Study Experiment in Northeastern Asia)
Period: 2001/12-2006/11 (Obs. 2002-: IOP 2003)
Objectives: Better understandings of the interaction between hyd
rosphere, atmosphere in the targeted region, and biosphere and human impact on it.
Target Area: upper Kherlen river basin
“snap-shot” view of hydrologic, ecological and atmospheric system of the region
MAHASRI NE Asia activity planResearch targets :
“Interannual variability” of hydroclimatorolgy with longer-time series of broader region
Background: Large Precipitation Variability – time & space

Diurnal variation in conjuction with rainfall processinter-annual variations, intra-annual variations in conjunction with the monsoon variability
Soil moisture and vegetation control of Landsurface processes
vegetation variability, soil-moisture dynamics and their control on the landsurface processesthe response of larch forest to the external forcing

Infiltration
Inter- and intra-annual variation of precipitation
Soil moisture and vegetation control on land surface processes
Redistribution, infiltration, river discharge and grandwater flow in semi-arid region
Vegetation
Sattelite monitoring of vegetation and soil moisture
Landsurface feedbacksResearch flow
Observation plans 1Kherlen river basin:
monitoring continued the 2 tower sites (CEOP2 reference sites, 2007-2010)
Forest site Grassland site (KBU)
Observation plans 2ULB region (in cooperation with IORGC):
Radar data (near ULB airport), rain gauge mesonet (will be setup)
groundwater monitoring (in cooperation with UNESCO-IHP)
Satellite monitoring of vegetation and soil moisture
validation with the surface obs.
Some data will be open to the public through CEOP 2 data archive.
