Space-time calibration of wind speed forecasts from regional climate models

Numerical weather predictions (NWP) are systematically subject to errors due to the deterministic solutions used by numerical models to simulate the atmosphere. Statistical postprocessing techniques are widely used nowadays for NWP calibration. However, time-varying bias is usually not accommodated by such models. Its calibration performance is also sensitive to the temporal window used for training. This paper proposes space-time models that extend the main statistical postprocessing approaches to calibrate NWP model outputs. Trans-Gaussian random fields are considered to account for meteorological variables with asymmetric behavior. Data augmentation is used to account for censuring in the response variable. The benefits of the proposed extensions are illustrated through the calibration of hourly 10 m wind speed forecasts in Southeastern Brazil coming from the Eta model.Comment: 43 pages, 13 figure

Risk assessment of water contamination by agrochemical in watershed.

Intensive agricultural systems are based on the heavy use of pesticides and fertilizers. This fact offer a high contamination risk of the natural resources, even when adequate technical of storage, application and disposal are used. Brasil used in 1993 61,845t of active ingredients of pesticides (insecticide, fungicide and herbicide) and 11,424,635 t of fertilizers (phosphorus, nitrogen and potassium), being the application rates variable as a function of region and crop plants. The use was very high, for example, in corn, cotton, orange, potato, soybean, sugar-cane and tomato in the east region of Rio Parana basin. The risk of agrochemical contamination of the natural resource varies according to the environment and product properties, therefore it is necessary to improve the knowledge about environment/product relation in order to permit a space-temporal management on application of these products, to reduce the risks. In our country, because its large surface area (8,500,000 km2) the data of environmental properties are poorly detailed and are not continuous in time and space. We have access to good information about properties of the used products, but few information is available about the quantity, the site and the method of their application. This work was done with all these things in mind and with the objective of the establishment of a method which permits a first approximation to identify areas with high risk of water contamination by agrochemical. We decided only use data which are available to everyone, in order to facilitate the method acceptance. The basic idea was that the water is the main agrochemical transport medium after its application in the crop field, and the environmental properties involved in the water moving (here considerated only in liquid state) are soil type, terrain slope and precipitation rate. An algorithm was built, based upon logical relationship matrixes, which permits to establish the water runoff and infiltration potential by crossing information of soil and terrain slope. This crossing was done by geographic information of soil and terrain slope. This crossing was done by geographic information system IDRISI, using like example the data of the Corrego Espraiado watershed, Ribeirao Preto county, Sao Paulo, Brasil. Maps were generated with the localization of the areas with high, medium and low water runoff and infiltration (one is opposite of the other) potentials. The areas were quantified, resulting that from the total 4,463ha of the watershed, 1,779ha had high (low) runoff (infiltration) potential. Maps which permits the identification of the areas which have greater risk of water contamination in the watershed has been generated. These maps can be made on monthly, seasonal (dry, normal and rainy seasons) or annual basis, for the main products used in any other watershed that has similar data availability

Análise estatística multivariada aplicada em amostras de água subterrânea da região do Cariri, sul do Estado do Ceará

In the area constituted by the municipalities of Barbalha, Crato and Juazeiro do Norte, south of Ceará State, groundwater resources are the only source of public and private water supply, and overexploitation is already evident in the intermittency of the old perennial drainage network, now perpetuated by sewage launches. The chemical evolution of groundwater was studied by identifying of similarities between physicochemical variables, discriminating the most significant ones, through the methodology of multivariate statistical analysis to explain possible processes responsible for water quality in the area. The factorial analysis identified three components responsible for approximately 85% of the total variance; the first one as an indicator of the dissolution of the minerals present in the Rio da Batateira and Santana formations; the second and third factors as indicators of a possible mixture between the natural waters of the aquifer with polluted waters. Multivariate cluster analysis by component showed four groups in factor 1 and two groups in factors 2 and 3, identified by samples with different concentration ranges. In the discriminant analysis, the most significant variables in the processes responsible for the hydrochemical evolution of the area were Mg2+ and K+ , being able to be related to ion exchange processes and weathering of feldspars.Na área constituída por parte dos municípios de Barbalha, Crato e Juazeiro do Norte, sul do Estado do Ceará, os recursos hídricos subterrâneos são a única fonte de abastecimento público e privado e a superexplotação já é evidenciada na intermitência da antiga rede de drenagem perene, hoje perenizada por lançamentos de esgotos. A evolução química das águas subterrâneas foi estudada identificando similaridades entre variáveis físico-químicas, discriminando as mais significativas, através da metodologia da análise estatística multivariada para explicar possíveis processos responsáveis pela qualidade das águas na área. A análise fatorial identificou três componentes responsáveis por aproximadamente 85% da variância total; o primeiro como indicador da dissolução dos minerais presentes na Formação Rio da Batateira e Formação Santana; o segundo e o terceiro fatores como indicadores de uma possível mistura entre as águas naturais do aquífero com águas poluídas. A análise de agrupamento multivariada por componente, apresentou quatro grupos no fator 1 e dois grupos nos fatores 2 e 3, identificados por amostras com diferentes faixas de concentrações. Na análise discriminante, as variáveis mais significativas nos processos responsáveis pela evolução hidroquímica da área foram o Mg2+ e K+ , podendo estar relacionados a processos de troca iônica e intemperismo de feldspatos

A comparison between time of exposure, number of pitfall traps and the sampling cost to capture ground-dwelling poneromorph ants (Hymenoptera: Formicidae)

Using effective survey protocols to address the effects of environmental change are key to saving time, resources and costs. Although exhaustive sampling in any location has been shown as impractical, biodiversity sampling projects must capture sufficient information to show how species assemblages change with the environmental variables. This study investigated time of exposure in the field and the number of pitfall traps that efficiently sampled poneromorph ants in 30 250 m long plots across an area of 25 km2 of tropical rain forest in Brazil. The treatments used for the surveys included two days and 300 traps, 14 days and 300 traps, 14 days and 750 traps, and were considered the minimum, intermediate and maximum sampling efforts, respectively. We characterized each assemblage of ants in relation to a gradient of soil texture, terrain slope and leaf and branch litter volume, and then tested whether the ecological relationships observed with the maximum effort were comparable to data on intermediate and minimum sampling efforts. We also estimated the cost-effectiveness of using the protocols in survey programs. The assemblage of species sampled during 14 days was similar to the assemblage captured during two days, indicating that the number of days influenced the assemblage similarity more than the number of sampling traps. All ecological patterns detected with the maximum effort were also captured with lesser sampling efforts. Overall, both the intermediate and minimum sampling efforts represented savings around 2640% of total project costs and 4345% of time to process the samples. We recommend that two days of trapping time combined with 300 pitfall traps is a highly effective shortcut for monitoring assessment, which can be applied to large-scale biodiversity surveys in tropical forests. © 2018 Universidade Estadual de Feira de Santana.
