Upscaling Of Land Surface Parameters Through Inverse Svat Modeling

by , Upscaling Of Land Surface Parameters Through Inverse Svat Modeling Book available in PDF, EPUB, Mobi Format. Download Upscaling Of Land Surface Parameters Through Inverse Svat Modeling books, The accurate representation of subgrid scale effects in climate models has been an issue of great controversy. In attempt to resolve this controversy, a model-independent technique was developed in this study to upscale land surface parameters through inverse-SVAT modeling. Upscaling laws are derived, that map the distributed land surface parameters of a heterogeneous land surface to their corresponding effective parameter. Simpler averaging methods of comparable performance are derived from the inverse modeling results, which drastically reduce the computational effort. The proposed method shows better performance than most well known methods. More importantly, the method is applicable in many fields.

Self Organized Surface Patterns Originating From Femtosecond Laser Induced Instability

by Olga Varlamova, Self Organized Surface Patterns Originating From Femtosecond Laser Induced Instability Book available in PDF, EPUB, Mobi Format. Download Self Organized Surface Patterns Originating From Femtosecond Laser Induced Instability books, Zusammenfassung/English The phenomenon of laser-induced periodic surface structures (LIPSS), or ripples, generated by femtosecond laser pulses on various solid targets is considered in this dissertation. The experimental observations and an astounding similarity of the structures to other patterns originating from instabilities led to the idea to attribute the femtosecond laser nanostructuring to a self-organized pattern formation from laser-induced surface instability. The main aim of the work is a better understanding of the fundamental processes of laser-matter interaction resulting in pattern formation by femtosecond laser ablation. The problem is of great interest both in fundamental and applied science. The knowledge of the underlying physical mechanisms will provide the opportunity to control surface nanostructuring, which has a big application potential in many modern technologies. Zusammenfassung/Deutsch Diese Dissertation beschäftigt sich mit dem Phänomen der Laser-Induzierten Periodischen Oberflächenstrukturen (LIPSS, Ripples), erzeugt bei der Ablation durch ultrakurze Lichtimpulsen an unterschiedlichen Targetmaterialien. Die experimentelle Beobachtungen und eine erstaunliche Ähnlichkeit der Strukturen zu anderen Mustern, die aus Instabilitäten entstehen, haben zur Idee geführt, die Entwicklung der Nanostrukturen im Rahmen einer Oberflächenselbstorganisation aus einer laserinduzierten Instabilität zu erklären. Das wesentliche Ziel der Arbeit bestand darin, die fundamentale Physik der Oberflächenstrukturierung bei der Femtosekundenlaserablation besser zu verstehen. Die Kenntnis der physikalischen Mechanismen hilft, die Nanostrukturierung von Oberflächen zu kontrollieren, die ein großes Anwendungspotenzial in vielen modernen Technologien bietet. https://www.researchgate.net/profile/Olga_Varlamova/

Sensitivity Tests Of A Surface Layer Windflow Model To Effects Of Stability And Vegetation

by John M. Lanicci, Sensitivity Tests Of A Surface Layer Windflow Model To Effects Of Stability And Vegetation Book available in PDF, EPUB, Mobi Format. Download Sensitivity Tests Of A Surface Layer Windflow Model To Effects Of Stability And Vegetation books, This study examines the sensitivity of surface-layer windflow over gently rolling terrain to different stability conditions, both with and without the effects of vegetation used to modify terrain heights and determine surface roughness. The numerical model used produces simulations of surface-layer windflow by using Gauss's Principle of Least Constraints to allow an initially uniform windfield to adjust to topography and buoyancy forces while conserving mass. The model experiments used simulated meteorological data (at only one observation point) and detailed terrain and vagetation data (on a 51-by-51 grid with 100 m spacing) for an area covering 5 by 5 km over the Fort Polk Military Reservation in Louisiana. Results show that the model simulates topographically induced flows such as cold air drainage and upslope flow, despite the simple physics employed. We also show that the presence to tall vegetation over the area (mainly coniferous and deciduous trees) alters the flow patterns under various stability conditions. These effects are shown to be caused primarily by changes in the area of chemical transport and diffusion, because they mean that even gently rolling terrain influences the surface windflow, and that tall vegetation has a considerable influence as well.
