Comparing surface-soil moisture from the SMOS mission and the ORCHIDEE land-surface model over the Iberian Peninsula

The aim of this study is to compare the surface soil moisture (SSM) retrieved from ESA's Soil Moisture and Ocean Salinity mission (SMOS) with the output of the ORCHIDEE (ORganising Carbon and Hydrology In Dynamic EcosystEm) land surface model forced with two distinct atmospheric data sets for the period 2010 to 2012. The comparison methodology is first established over the REMEDHUS (Red de Estaciones de MEDición de la Humedad def Suelo) soil moisture measurement network, a 30 by 40. km catchment located in the central part of the Duero basin, then extended to the whole Iberian Peninsula (IP). The temporal correlation between the in-situ, remotely sensed and modelled SSM are satisfactory (r. >. 0.8). The correlation between remotely sensed and modelled SSM also holds when computed over the IP. Still, by using spectral analysis techniques, important disagreements in the effective inertia of the corresponding moisture reservoir are found. This is reflected in the spatial correlation over the IP between SMOS and ORCHIDEE SSM estimates, which is poor (¿. ~. 0.3). A single value decomposition (SVD) analysis of rainfall and SSM shows that the co-varying patterns of these variables are in reasonable agreement between both products. Moreover the first three SVD soil moisture patterns explain over 80% of the SSM variance simulated by the model while the explained fraction is only 52% of the remotely sensed values. These results suggest that the rainfall-driven soil moisture variability may not account for the poor spatial correlation between SMOS and ORCHIDEE products.Peer ReviewedPostprint (published version

Nested Rules in Defeasible Logic

Defeasible Logic is a rule-based non-monotonic logic with tractable reasoning services. In this paper we extend Defeasible Logic with nested rules. We consider a new Defeasible Logic, called DL^ns, where we allow one level of nested rules. A nested rule is a rule where the antecedent or the consequent of the rule are rules themselves. The inference conditions for DL^ns are based on reflection on the inference structures (rules) of the particular theory at hand. Accordingly DL^ns can be considered an amalgamated reflective system with implicit reflection mechanism. Finally we outline some possible applications of the logic

Extracción agrícola de bases en el norte de la provincia de Buenos Aires, Argentina : costo de su remediación e implicancias económicas

El lavado de nutrientes edáficos básicos, su extracción agropecuaria, la fertilización y la deposición de compuestos de N, S e H presentes en la atmósfera, entre otros, causan acidificación edáfica. La escasez y el desbalance nutricional ocasionado limita la producción vegetal. Este fenómeno se advirtió recientemente en la Región Pampeana Argentina, donde la reposición de Ca2+, Mg2+ y K+ ha sido limitada en el pasado. El objetivo del trabajo fue evaluar la extracción de bases causada por la agricultura en el norte de la provincia de Buenos Aires (1.684.753 ha) durante el período 1970-2003, cuantificar económicamente su remediación y analizar sus implicancias económicas. La extracción de K+, Ca2+ y Mg2+ fue estimada en 682.692, 88.443 y 155.479 Mg totales para la región, respectivamente, en el período considerado. El costo de la reposición para suelos cultivados con soja, maíz, trigo y girasol es de 414.000.000; 127.300.000; 86.200.000 y 16.000.000, representando 6,6%, 3,4%, 4,0% y 2,9% del ingreso debido a su producción. El análisis socioeconómico regional señala condiciones actuales de agravamiento de los factores predisponentes a la problemática edáfica, la potencialidad de perjuicios económicos para la región y el país, y marca la necesidad de estrategias de gestión que favorezcan la reposición de estos elementos.The leaching of basic edaphic nutrients, its farming extraction, fertilization and the N, S and H compounds deposition from the atmosphere, among others, cause edaphic acidification. The shortage and provoked nutritional unbalance limit the vegetal production. This phenomenon has recently been noticed in the Pampeana Region of Argentina, where the replacement of Ca2+, Mg2+ and K+ was limited in the past. The objective of this work has been to evaluate the extraction of bases caused by agriculture in the north of the province of Buenos Aires (1,684,753 ha) within the mentioned region (1970-2003), to quantify economically its remediation and to analyze its socioeconomic implications.Principio del formulario The extraction of K+, Ca2+ and Mg2+ has been estimated in 682,692; 88,443 and 155,479 Mg for the total region, respectively, and the considered period. Replacement costs are 414.000.000; 127.300.000; 86.200.000 and 16.000.000 for fields cultivated with soybean, maize, sunflower and wheat, representing 6.6%, 3.4%, 4.0% y 2.9% of the income derived from its production. The regional socioeconomic analysis indicates present conditions worsening of the predisposing factors to the edaphic problematic situation, the potentiality of economic damages for the region and the country, and it marks the necessity of management strategies that favor the replacement of these elements

SYNSEDIMENTARY TECTONICS AND SEDIMENTATION IN THE TERTIARY PIEDMONT BASIN, NORTHWESTERN ITALY

The Late Oligocene/Early Miocene tectonic and sedimentary evolution of the eastern sector of the Langhe Sub-Basin (Teriary Piedmont Basin) is proposed and discussed. The area is located between the villages of Roccaverano and Mombaldone, along the western side of the Bormida di Spigno River Valley (see attached geologic map). Synsedimentary tectonics strongly influenced the geologic evolution of the region during the time span examined, being particularly evident at three specific "times" that were chosen as models. During "Time 1" (Late Oligocene) gentle anticlines, aligned WNW-ESE and NW-SE, started to form, affecting only hemipelagic mudstones and creating structural highs that controlled the areal distribution of both turbidites (i.e.T. Ovrano High) and a thick pelitic slump sheet (i.e.M. Pisone High). During "Time 2"(Aquitanian) the C. Mazzurini Half-Graben developed, separated by W-E and WNW-ESE growth faults from the M. Ovrano High to the north and gradually connecting, through a gently sloping ramp, with the Rocchetta High to the south. Turbidity currents and debris flows were channeled into the half-graben, while hemipelagic limestones were deposited onto the adjacent higher areas. During "Time 3" (Early Burdigalian) the depocenter of the depression shifted southward, while the half-graben evolved into a wide trough (Piantivello Trough) characterized by turbidites. Subsequently, the strongly irregular topography was progressively leveled to the quite homogeneous landscape on which the Cortemilia Formation (Late Burdigalian) was deposited.
