全球数以百万计的人依靠湖泊提供多种多样的生态系统服务,人类也使用湖泊作为食物来源和多种经济活动,并且许多生物类群也依赖湖泊生存。然而,尽管湖泊的重要性,我们仍然缺乏人类活动对全球湖泊影响的评估。近日,我院克里斯托(Christos Mammides)副教授在环境科学顶尖期刊《Global Environmental Change》上发表题为:“A global assessment of the ...
INTEGRATION OF SATELLITE, GLOBAL REANALYSIS DATA AND MACROSCALE HYDROLOGICAL MODEL FOR DROUGHT ASSESSMENT IN SUB-TROPICAL REGION OF INDIA
VIC Soil Moisture Agricultural drought SMDI CCI
2018/5/15
Change in soil moisture regime is highly relevant for agricultural drought, which can be best analyzed in terms of Soil Moisture Deficit Index (SMDI). A macroscale hydrological model Variable Infiltra...
Global land-surface evaporation estimated from satellite-based observations
Global land-surface satellite-based observations evaporation estimated
2011/3/14
This paper outlines a new strategy to derive evaporation from satellite observations. The approach uses a variety of satellite-sensor products to estimate daily evaporation at a global scale and 0.25 ...
Groundwater use for irrigation – a global inventory
Groundwater irrigation global inventory
2010/12/22
Irrigation is the most important water use sector accounting for about 70% of the global freshwater withdrawals and 90% of consumptive water uses. While the extent of irrigation and related water uses...
