Advancing Earth Surface Representation via Enhanced Use of Earth Observations in Monitoring and Forecasting Applications
The representation of the Earth's surface in global monitoring and forecasting applications is moving towards capturing more of the relevant processes, while maintaining elevated computational efficiency and therefore a moderate complexity. These schemes are developed and continuously improved thanks to well instrumented field-sites that can observe coupled processes occurring at the surface–atmosphere interface (e.g., forest, grassland, cropland areas and diverse climate zones). Approaching global kilometer-scale resolutions, in situ observations alone cannot fulfil the modelling needs, and the use of satellite observation becomes essential to guide modelling innovation and to calibrate and validate new parameterization schemes that can support data assimilation applications. In this book, we review some of the recent contributions, highlighting how satellite data are used to inform Earth surface model development (vegetation state and seasonality, soil moisture conditions, surface temperature and turbulent fluxes, land-use change detection, agricultural indicators and irrigation) when moving towards global km-scale resolutions.
Next Generation Earth System Prediction
As the nation's economic activities, security concerns, and stewardship of natural resources become increasingly complex and globally interrelated, they become ever more sensitive to adverse impacts from weather, climate, and other natural phenomena. For several decades, forecasts with lead times of a few days for weather and other environmental phenomena have yielded valuable information to improve decision-making across all sectors of society. Developing the capability to forecast environmental conditions and disruptive events several weeks and months in advance could dramatically increase the value and benefit of environmental predictions, saving lives, protecting property, increasing eco...
Il tatuaggio insanguinato
Non sempre la normalità e il benessere sono sinonimo di tranquillità. Può capitare, infatti, che il fato nasconda dietro l'angolo un imprevisto, quell'imponderabile situazione che, energicamente, cambia all'improvviso lo status quo. Tutto questo è capitato in una tranquilla città marchigiana e pugliese, tanto distanti tra loro ma accomunate da terribili fatti di sangue che, come un incubo, finiranno per spazzare la tranquillità dei loro abitanti, sino a quel momento abituati a trascorrere le giornate immersi nel lavoro e lontano da ogni forma di violenza. Il velo della morte incombente, però, ridimensionerà ogni cosa. Per un commissario di Polizia e un giornalista di cronaca nera nulla sarebbe stato come prima...
The Earth's Hydrological Cycle
This book gives a comprehensive presentation of our present understanding of the Earth's Hydrological cycle and the problems, consequences and impacts that go with this topic. Water is a central component in the Earth's system. It is indispensable for life on Earth in its present form and influences virtually every aspect of our planet's life support system. On relatively short time scales, atmospheric water vapor interacts with the atmospheric circulation and is crucial in forming the Earth's climate zones. Water vapor is the most powerful of the greenhouse gases and serves to enhance the tropospheric temperature. The dominant part of available water on Earth resides in the oceans. Parts ar...
Sub-seasonal to Seasonal Prediction
The Gap Between Weather and Climate Forecasting: Sub-seasonal to Seasonal Prediction is an ideal reference for researchers and practitioners across the range of disciplines involved in the science, modeling, forecasting and application of this new frontier in sub-seasonal to seasonal (S2S) prediction. It provides an accessible, yet rigorous, introduction to the scientific principles and sources of predictability through the unique challenges of numerical simulation and forecasting with state-of-science modeling codes and supercomputers. Additional coverage includes the prospects for developing applications to trigger early action decisions to lessen weather catastrophes, minimize costly dama...
New Approaches to Hydrological Prediction in Data-sparse Regions
When data are scarce, hydrological predictions become unreliable, mainly due to the inability to specify model components and parameter values that consistently represent the dominant hydrological processes in a particular basin, and also due to the lack of high quality model forcing. This is a problem in developed and developing countries, and the focus of much research worldwide. This proceedings volume, from a symposium of the same name heldin Hyderabad, India, September 2009, contains 40 papers from over 20 countries. They reflect differing aspects of, and approaches to, the problem and are grouped accordingly: Hydrological modelling in poorly gauged and ungauged basins Hydrometeorology and climate change assessment Remote sensing applications in hydrology Characterizing rainfall variability & its impacts on hydrological modelling
La libertà ritrovata
Nella tradizione biblica, l’ulivo portato a Noè sull’Arca dalla colomba è il segno che, finalmente, è cessato il diluvio. Un segno di speranza, dunque. Raffigurato nella sua sinuosa maestosità sulla copertina di questo libro diventa ancora di più simulacro di Vita e di fiducia, a imperitura memoria di come sia necessario tutelare questi monumentali arbusti secolari e salvaguardare il territorio che li ospita dalle aggressioni antropiche, di una criminalità sempre più agguerrita pronta a violentarlo e sfregiarlo pur di realizzare loschi profitti. E proprio all’ombra di uno di questi monumenti vegetali, contorti e rinvigoriti dallo scorrere ineluttabile del tempo, la prolifica fan...
