Seyed Hamed Alemohammad et al.
A new global estimate of surface turbulent fluxes, latent heat flux (LE) and sensible heat flux (H), and gross primary production (GPP) is developed using a machine learning approach informed by novel remotely sensed Solar-Induced Fluoresce...
Effects of different N sources on riverine DIN export and retention in a subtropical high-standing island, Taiwan [0.03%]
氮素来源对台湾亚热带高山岛河流带溶解性无机氮输移的影响

The methane (CH4) and nitrous oxide (N2O) exchange of a temperate mountain grassland near Neustift, Austria, was measured during 2010-2012 over a time period of 22 months using the eddy covariance method. Exchange rates of both compounds at...
Development of a regional-scale pollen emission and transport modeling framework for investigating the impact of climate change on allergic airway disease [0.03%]
用于研究气候变化对过敏性呼吸道疾病影响的区域尺度花粉排放和传输模拟框架的研发工作

Rui Zhang et al.
Exposure to bioaerosol allergens such as pollen can cause exacerbations of allergenic airway disease (AAD) in sensitive populations, and thus cause serious public health problems. Assessing these health impacts by linking the airborne polle...
Leaf area controls on energy partitioning of a temperate mountain grassland [0.03%]

Grasslands comprise natural tropical savannah over managed temperate fields to tundra and cover one quarter of the Earth's land surface. Plant growth, maintenance and decay result in volatile organic compound (VOCs) emissions to the atmosph...
Estimating carbon dioxide fluxes from temperate mountain grasslands using broad-band vegetation indices [0.03%]
采用宽带植被指数估算温带草原碳 dioxide 通量
G Wohlfahrt,S Pilloni,L Hörtnagl et al.
G Wohlfahrt et al.
The broad-band normalised difference vegetation index (NDVI) and the simple ratio (SR) were calculated from measurements of reflectance of photosynthetically active and short-wave radiation at two temperate mountain grasslands in Austria an...
Land use affects the net ecosystem CO(2) exchange and its components in mountain grasslands [0.03%]
土地利用影响山地草甸生态系统二氧化碳交换及其组分
M Schmitt,M Bahn,G Wohlfahrt et al.
M Schmitt et al.
Changes in land use and management have been strongly affecting mountain grassland, however, their effects on the net ecosystem exchange of CO(2) (NEE) and its components have not yet been well documented. We analysed chamber-based estimate...
