A perspective on the fundamental quality of GPS radio occultation data
Authors: Wee T.-K. , Kuo Y.-H.
Published: September 2014

Abstract. Radio Occultation (RO) is a promising source of observation for weather and climate applications. However, the uncertainties in processing and retrieving RO data may weaken the overall confidence in the data and discourage their use. This study assesses the fundamental quality of RO data, by modeling the "raw" measurement, phase path, through a ray tracing method without the nuisance of retrieval errors. The comparison of phase measurements with the European Center for Medium-Range Weather Forecasts (ECMWF) data made in the observation space shows that the RO measurement is of sufficient accuracy to uncover regional-scale systematic errors in ECMWF's operational analysis and the 45 year reanalysis (ERA40), and to clearly depict the error growth of short-term ERA40 forecasts. In the southern hemispheric stratosphere, in particular, the RO measurement served as a robust reference against which both of the two analyses were significantly biased in opposite directions even though they were produced by the same center using virtually the same set of data. The measurement and ECMWF analyses showed a close agreement in the standard deviation. This confirms the high accuracy of the RO measurement and also indicates that the main problem of the ECMWF analyses lies in their systematic error.

Abstract. The ice content of mixed phase clouds, which contain both supercooled water and ice, affects both their lifetime and radiative properties. In many clouds, the formation of ice requires the presence of particles capable of nucleating ice. One of the most important features of ice nucleating particles (INPs) is that they are rare in comparison to cloud condensation nuclei. However, the fact that only a small fraction of aerosol particles can nucleate ice means that detection and quantification of INPs is challenging. This is particularly true at temperatures above about −20 °C since the population of particles capable of serving as INPs decreases dramatically with increasing temperature. In this paper, we describe an experimental technique in which droplets of microlitre volume containing ice nucleating material are cooled down at a controlled rate and their freezing temperatures recorded. The advantage of using large droplet volumes is that the surface area per droplet is vastly larger than in experiments focused on single aerosol particles or cloud-sized droplets. This increases the probability of observing the effect of less common, but important, high temperature INPs and therefore allows the quantification of their ice nucleation efficiency. The potential artefacts which could influence data from this experiment, and other similar experiments, are mitigated and discussed. Experimentally determined heterogeneous ice nucleation efficiencies for K-feldspar (microcline), kaolinite, chlorite, Snomax®, and silver iodide are presented.
Response of CH4 emissions to moss removal and N addition in boreal peatland of northeast China

Published: September 2014

Abstract. Boreal peatlands are an important natural source of atmospheric methane (CH4). Recently, boreal peatlands have been experiencing increased nitrogen (N) availability and decreased moss production. However, little is known about the interactive effect of moss and N availability on CH4 emissions in boreal peatlands. In this study, the effects of moss removal and N addition (6 g N m−2 yr−1) on CH4 emissions were examined during the growing seasons of 2011, 2012 and 2013 in a boreal peatland in the Great Hinggan Mountain of northeast China. Notably, the response of CH4 emissions to moss removal and N addition varied with experimental duration. Moss removal and N addition did not affect CH4 emissions in 2011 and 2012, but respectively reduced CH4 emissions by 50% and 66% in 2013. However, moss removal and N addition did not produce an interactive effect on CH4 emissions. Consequently, moss removal plus N addition had no effect on CH4 emissions in 2011 and 2012, but decreased CH4 emissions by 68% in 2013. These results suggest that the effects of moss removal and N enrichment on CH4 emissions are time-dependent in boreal peatlands, and also imply that increased N availability and decreased moss growth would independently inhibit CH4 emissions in the boreal peatlands of northeast China.
Interannual climate variability seen in the Pliocene Model Intercomparison Project
Authors: Brierley C. M.
Published: September 2014

Abstract. Following proxy observations of weakened temperature gradients along the Equator in the early Pliocene, there has been much speculation about Pliocene climate variability. A major advance for our knowledge about the later Pliocene has been the coordination of modelling efforts through the Pliocene Model Intercomparison Project (PlioMIP). Here the changes in interannual modes of sea surface temperature variability will be presented across PlioMIP. Previously model ensembles have shown little consensus in the response of the El Niño–Southern Oscillation (ENSO) to imposed forcings – either for the past or future. The PlioMIP ensemble, however, shows surprising agreement with eight models simulating reduced variability and only one model indicating no change. The Pliocene's robustly weaker ENSO also saw a shift to lower frequencies. Model ensembles focussed at a wide variety of forcing scenarios have not yet shown this level of coherency. Nonetheless the PlioMIP ensemble does not show a robust response of either ENSO flavour or sea surface temperature variability in the Tropical Indian and North Pacific Oceans. Existing suggestions of ENSO properties linked to changes in zonal temperature gradient, seasonal cycle and the elevation of the Andes Mountains are investigated, yet prove insufficient to explain the coherent response. The reason for this surprisingly coherent signal warrants further investigation.
Integration of Geographic Information System frameworks into domain discretisation and meshing processes for geophysical models
Authors: Candy A. S. , Avdis A. , Hill J. , Gorman G. J. , Piggott M. D.
Published: September 2014

Abstract. Computational simulations of physical phenomena rely on an accurate discretisation of the model domain. Numerical models have increased in sophistication to a level where it is possible to support terrain-following boundaries that conform accurately to real physical interfaces, and resolve a multiscale of spatial resolutions. Whilst simulation codes are maturing in this area, pre-processing tools have not developed significantly enough to competently initialise these problems in a rigorous, efficient and recomputable manner. In the relatively disjoint field of Geographic Information Systems (GIS) however, techniques and tools for mapping and analysis of geographical data have matured significantly. If data provenance and recomputability are to be achieved, the manipulation and agglomeration of data in the pre-processing of numerical simulation initialisation data for geophysical models should be integrated into GIS. A new approach to the discretisation of geophysical domains is presented, and introduced with a verified implementation. This brings together the technologies of geospatial analysis, meshing and numerical simulation models. This platform enables us to combine and build up features, quickly drafting and updating mesh descriptions with the rigour that established GIS tools provide. This, combined with the systematic workflow, supports a strong provenance for model initialisation and encourages the convergence of standards.
Developing a nutrient pollution model to assist policy makers by using a meso-scale Minimum Information Requirement (MIR) approach
Authors: Adams R. , Quinn P. F. , Bowes M. J.
Published: September 2014

Abstract. A model for simulating runoff pathways and water quality fluxes has been developed using the Minimum Information (MIR) approach. The model, the Catchment Runoff Attenuation Tool (CRAFT) is applicable to meso-scale catchments which focusses primarily on hydrological pathways that mobilise nutrients. Hence CRAFT can be used investigate the impact of management intervention strategies designed to reduce the loads of nutrients into receiving watercourses. The model can help policy makers, for example in Europe, meet water quality targets and consider methods to obtain "good" ecological status. A case study of the 414 km2 Frome catchment, Dorset UK, has been described here as an application of the CRAFT model. The model was primarily calibrated on ten years of weekly data to reproduce the observed flows and nutrient (nitrate nitrogen – N – and phosphorus – P) concentrations. Also data from two years of sub-daily high resolution monitoring at the same site were also analysed. These data highlighted some additional signals in the nutrient flux, particularly of soluble reactive phosphorus, which were not observable in the weekly data. This analysis has prompted the choice of using a daily timestep for this meso-scale modelling study as the minimum information requirement. A management intervention scenario was also run to show how the model can support catchment managers to investigate how reducing the concentrations of N and P in the various flow pathways. This scale appropriate modelling tool can help policy makers consider a range of strategies to to meet the European Union (EU) water quality targets for this type of catchment.
Climate and hydrological variability: the catchment filtering role
Authors: Andrés-Doménech I. , García-Bartual R. , Montanari A. , Marco J. B.
Published: September 2014

Abstract. Measuring the impact of climate change on flood frequency is a complex and controversial task. Identifying hydrological changes is difficult given the factors, other than climate variability, which lead to significant variations in runoff series. The catchment filtering role is often overlooked and in fact, this may hinder the correct identification of climate variability signatures on hydrological processes. Does climate variability necessarily imply hydrological variability? The research herein presented aims to analytically derive the flood frequency distribution basing on realistic hypotheses about the rainfall process and the rainfall–runoff transformation. The peak flow probability distribution is analytically derived to quantify the filtering effect operated by the rainfall–runoff process on climate change. A sensitivity analysis is performed according to typical semi-arid Mediterranean climatic and hydrological conditions, assuming a simple but common scheme for the rainfall–runoff transformation in small-size ungauged catchments, i.e. the CN-SCS model. Variability in peak flows and its statistical significance are analysed when changes in the climatic input are introduced. Results show that in regard to changes in the annual number of rainfall events, the catchment filtering role is particularly significant when the event rainfall volume distribution is not strongly skewed. Results largely depend on the return period: for large return periods, peak flow variability is significantly impacted by the climatic input, while for lower return periods, infiltration processes smooth out the effects of climate change.
Estimating time delays for constructing dynamical networks
Authors: Martin E. A. , Davidsen J.
Published: September 2014

Abstract. Dynamical networks – networks inferred from multivariate time series – have been widely applied to climate data and beyond, resulting in new insights into the underlying dynamics. However, these inferred networks can suffer from biases that need to be accounted for to properly interpret the results. Here, we report on a previously unrecognized bias in the estimate of time delays between nodes in dynamical networks inferred from cross-correlations, a method often used. This bias results in the maximum correlation occurring disproportionately often at large time lags. This is of particular concern in dynamical networks where the large number of possible links necessitates finding the correct time lag in an automated way. We show that this bias can arise due to the similarity of the estimator to a random walk, and are able to map them to each other explicitly for some cases. For the random walk there is an analytical solution for the bias that is closely related to the famous Lévy arcsine distribution, which provides an upper bound in many other cases. Finally, we show that estimating the cross-correlation in frequency space effectively eliminates this bias. Reanalysing large lag links (from a climate network) with this method results in a distribution peaked near zero instead, as well as additional peaks at the originally assigned lag. Links that are reassigned smaller time lags tend to have a smaller distance between them, which indicates that the new time delays are physically reasonable.
Using empirical orthogonal functions derived from remote sensing reflectance for the prediction of concentrations of phytoplankton pigments

Published: September 2014

Abstract. The composition and abundance of algal pigments provide information on characteristics of a phytoplankton community in respect to its photoacclimation, overall biomass, and taxonomic composition. Particularly, these pigments play a major role in photoprotection and in the light-driven part of photosynthesis. Most phytoplankton pigments can be measured by High Performance Liquid Chromatography (HPLC) techniques to filtered water samples. This method, like others when water samples have to be analysed in the laboratory, is time consuming and therefore only a limited number of data points can be obtained. In order to receive information on phytoplankton pigment composition with a higher temporal and spatial resolution, we have developed a method to assess pigment concentrations from continuous optical measurements. The method applies an Empirical Orthogonal Function (EOF) analysis to remote sensing reflectance data derived from ship-based hyper-spectral underwater radiometric and from multispectral satellite data (using the MERIS Polymer product developed by Steinmetz et al., 2011) measured in the Eastern Tropical Atlantic. Subsequently we developed statistically linear models with measured (collocated) pigment concentrations as the response variable and EOF loadings as predictor variables. The model results, show that surface concentrations of a suite of pigments and pigment groups can be well predicted from the ship-based reflectance measurements, even when only a multi-spectral resolution is chosen (i.e. eight bands similar to those used by MERIS). Based on the MERIS reflectance data, concentrations of total and monovinyl chlorophyll a and the groups of photoprotective and photosynthetic carotenoids can be predicted with high quality. The fitted statistical model constructed on the satellite reflectance data as input was applied to one month of MERIS Polymer data to predict the concentration of those pigment groups for the whole Eastern Tropical Atlantic area. Bootstrapping explorations of cross-validation error indicate that the method can produce reliable predictions with relatively small data sets (e.g., < 50 collocated values of reflectance and pigment concentration). The method allows for the derivation of time series from continuous reflectance data of various pigment groups at various regions, which can be used to study variability and change of phytoplankton composition and photo-physiology.

Pricing American bond options using a cubic spline collocation method
Authors: El hajaji Abdelmajid , Hilal Khalid , Serghini Abdelhafid , Mermri El bekkey
Published: September 2014

In this paper, American options on a discount bond are priced under the Cox-Ingrosll-Ross (CIR) model. The linear complementarity problem of the option value is solved numerically by a penalty method. The problem is transformed into a nonlinear partial differential equation (PDE) by adding a power penalty term. The solution of the penalized problem converges to the one of the original problem. To numerically solve this nonlinear PDE, we use the horizontal method of lines to discretize the temporal variable and the spatial variable by means of trapezoidal method and a cubic spline collocation method, respectively. We show that this full discretization scheme is second order convergent, and hence the convergence of the numerical solution to the viscosity solution of the continuous problem is guaranteed. Numerical results are presented and compared with other collocation methods given in the literature.

Authors: Mohammadyari Reza , Rahimi-Esbo Mazaher , Khalili Asboei Alireza
Published: September 2014

In this article magneto hydrodynamics (MHD) boundary layer flow of compressible fluid in a channel with porous walls is researched. In this study it is shown that the nonlinear Navier-Stokes equations can be reduced to an ordinary differential equation, using the similarity transformations and boundary layer approximations. Analytical solution of the developed nonlinear equation is carried out by the Differential Transformation Method (DTM). In addition to applying DTM into the obtained equation, the result of the mentioned method is compared with a type of numerical analysis as Boundary Value Problem method (BVP) and a good agreement is seen. The effects of the Reynolds number and Hartman number are investigated.

É estudado o substrato natural dos estágios larvais de similídeos no Rio Marumbi (Morretes, Paraná, Brasil). É formado por plantas marginais e submersas. Fios plásticos amarelos e verdes foram usados como substratos artificiais e foi mostrado que os fios amarelos são os preferidos pelas larvas. A fauna associada aos imaturos é constituída de artrápodos e peixes. Larvas de Athericidae foram encontrada em matéria em decomposição. Abstract The natural substratum of the black flies larval stages on Marurnbi River (Morreres, Paraná, Brasil) were exaniined. lt was found to be constituted by marginal and submerged plants only. Yellow and green plastic threads as artificial substratum were used and showed that immatures prefer the yellow ones. The associated fauna to immatures was found to be constituted by arthropods and fishes. Athericidae larvae were found in decomposed organic material; this is the first citation of this farnily in Brazil.

Método para análise quantitativa de algas e outros itens microscópicos de alimentação de peixes
Authors: Aranha José Marcelo
Published: September 2014

Breve revisão crítica sobre os principais métodos de análise do conteúdo estomacal em peixes é o problema de sua ulilização em estudo quantitativo em peixes que ingerem itens microscópicos como algas. 0 método proposto é simples. não exige equipamentos dispendiosos e consiste basicamente na contagem de 15 campos de microscópio óptico sorteados dentre 90 campos definidos aleatóriamente também por sorteio. o número de campos para a contagem depende da varicdade de itens ingeridos pelo peixe, mas, quando testado, o número de 15 campos mostrouse adequado para a análise da diéta de três Poecilidae (Phalloceros caudimaculatus, Poecilia vivipara, Phallotycus januarius) e um Jenynsiidae (Jenyncia lineata). A importância numérica relativa de cada item deve ser expressa em percentagem do total de ítens contados. Estes resultados associados aos da freqüência de ocorrência permitirão a definição mais precisa da alimentação do peixe estudado. Abstract A short critical reiew of the principal methods of analysis of stomach contents is presented herein and the problems of their utilization in quantitative studies with fishes which feed microscopical itens (for exemple algae) is discussed. This method is simple and do not require expensive equipaments. It consists of couninig small food itens in fifteen optical microscopic fields alloted among ninety alcatorilv determined fields. The number of the fields counted depends on the variety of food itens that the fish eats. However tests performed on three Poeciltidae ((Phalloceros caudimaculatus , Poecilia vivipara, Phallotycus januarius) ) and a Jenynsiidae (Jenyncia lineata) indicate that 15 is an appropriat number. The numerical retative importance of each item will be expressed in percentage of the total of itens counted. This result associated with those of the occurrence frequency, will confer a greater precision on studies of feeding habits of the fish.

Strategies for habitat use among species of hunting spiders (Araneomorphae, Dionycha) in natural and artificial biotopes from southeastern Brazil
Authors: Rinaldi Isabela M. P.
Published: September 2014

Foram estudadas 247 espécies de aranhas (Araneomorphae, Dionycha) dos estratos arbustivo e arbóreo de seis ecossistemas na região de Botucatu, São Paulo, Brasil, e sua coexistência foi analisada por meio de uma matriz de comunidade. Espécies relativamente abundantes são predominantemente generalistas, independente de seu ambiente; espécies representadas apenas por poucos individuos foram numerosas, e consideradas como membros marginais das comunidades. 0 coeficiente rnédio de interação comunitária foi estimado para cada espécie, assim como a covariação para as espécies mais abundantes em cada ecossistema. Há evidéncia de que a distribuição agregada de plantas favorece as espécies mais especializadas. Abstract Two hundred and forty seven species of dionychan spiders from the shrub and tree layers of six habitats in the region of Botucatu, State of São Paulo, Brazil, were studied, and their strategies for Coexistence were determined through construction of a community matrix. Spiders with relatively greater abundance behaved largely as generalists, independent of their environment, species represented by only a few individuals were numerous, and were considered to be marginal members of the communities. Estimates of the average community interaction coefficient for each species, and of covariation of the more abundant species in each ecosystem, indicate that the spiders avoid competition by spatial partioning, or by adopting differential strategies for habitat use, or because they belong to different guilds. In relation to the aggregate distribution of plants, species tend to specialization, and thus alter their strategy to follow the availability of resources in the environment. These results, together with accumulated knowledge of the ecology of spiders, lead to observations on the subgroup as agent of stabilization in insect populations. Résumé Un programme de prospection des araignées a été realisé dans la region de Botucatu (São Paulo, Brésil). Les strates arbustifs et arboricoles de six écosystèmes on été echantillonnés et 247 espèces dáraignées (Araneomorphae, Dionycha) ont été recueillies. Leur coexistence a été analyseé par one matrice de communauté. Les espèces relativament abundantes sont dans la grande majorité des especes généralistes, quelque que soit leur habitat. Beaucoup despèces avaient peu d'individus et peuvent être considdrées comme espêces marginales. Le coefficient moyen d'interaction de communauté a été estimé pour chaque espèce, aussi bien que la covariation pour les espéces les plus abondantes dans chaque ecosystéme. Nous avons aperçu que la distribution agrégeé des plantes rend evident la presence des espèces les plus specialiseés.
