We report the discovery of new phase of carbon (referred to as Q-carbon) and address fundamental issues related to direct conversion of carbon into diamond at ambient temperatures and pressures in air...
ESTIMATION OF CARBON STOCKS IN NEW ZEALAND PLANTED FORESTS USING AIRBORNE SCANNING LIDAR
Kyoto Protocol forest inventory sampling carbon models
2015/11/10
To meet obligations under Article 3.3 of the Kyoto Protocol, New Zealand is required to estimate, in an unbiased manner, forest carbon stock change, over the Protocol’s first commitment period (2008-2...
SEASONAL COMPARISON OF CARBON FLUX ESTIMATES FROM C-TESSEL MODEL AND MODERATE RESOLUTION IMAGING SPECTRORADIOMETER (MODIS) OVER SEVERAL BIOMES
vegetation the atmosphere
2015/9/8
Carbon dioxide exchange between vegetation and the atmosphere is determined by absorption
of solar radiation by plant leaves and by turbulent transfer in the surface layer. This led to two
different...
ASSIMILATING REFLECTANCE DATA INTO A ECOSYSTEM MODEL TO IMPROVE ESTIMATES OF TERRESTRIAL CARBON FLUX
Ensemble Kalman filter MODIS GORT
2015/9/8
Ecosystem models are valuable tools for understanding the growth of vegetation, its response to climatic change and its role in the
cycling of greenhouse gasses. Data Assimilation (DA) of synoptic co...
Individual transistors made from carbon nanotubes are faster and more energy efficient than those made from other materials. Going from a single transistor to an integrated circuit full of transistors...
Remotely sensed soil moisture effects on carbon sequestration spatial patterns
Carbon sequestration soil moisture optical and thermal and radar remote sensing
