A RESISTÊNCIA É UM LUGAR SOLITÁRIO?: REFLEXÕES SOBRE AQUARIUS DE KLEBER MENDONÇA FILHO
No full textAquarius, filme de Kleber Mendonça Filho de 2016, narra à história de uma mulher que resiste. Assim, intransitivamente, Clara, a protagonista, mora há décadas em um edifício antigo de frente para a praia de Boa Viagem, no Recife. O prédio, que dá nome ao filme, está em processo de ser adquirido, apartamento por apartamento, por uma construtora que pretende derrubá-lo para construir um condomínio de luxo, mais moderno. No entanto, a empresa, representada pelo proprietário e seu neto, que foi estudar business nos Estados Unidos, encontra na figura de Clara um obstáculo: a mulher se recusa a vender o apartamento. Clara se nega a ceder às propostas, intimidações e ameaças da construtora. Ela resiste, mesmo que para isso acabe sendo taxada de louca, de velha chata, de barraqueira. Porque a resistência exige coragem, exposição, enfrentamento. Neste sentido, a proposta de análise Aquarius acaba por apontar para a reflexão do cotidiano, onde há pessoas resistindo diariamente, das mais diversas formas, muitas vezes sem serem notadas. Há várias Claras ao nosso redor. Nós as conhecemos, vivemos e trabalhamos com ela. Às vezes, somos nós. Os padrões impostos pela sociedade que vivemos, o mercado e os interesses de quem têm mais poder espera que as pessoas se conformem, sigam o que foi estabelecido, obedeçam. Nesse contexto, dizer “não” se transforma em um ato político.
Fusion of SMOS and Aquarius Level 3 SSS Maps by Spatial Optimization of the Error Matrix
No full textSMOS & Aquarius Science Workshop, 15-17 April 2013, Brest, FranceThe retrieval of Sea Surface Salinity (SSS) with SMOS and Aquarius missions is very challenging, due to the limited sensibility of brightness temperatures in L-band to SSS. However, salinity is one of the worst known Essential Climate Variables and its acquisition is crucial for the full understanding of the water cycle and utterly of Earth's climate system. Errors in SMOS and Aquarius acquisitions are of diverse origin: incorrect geophysical modeling, systematic antenna patterns, galactic noise, land-sea contamination, RFI sources, seasonal biases... In spite of all those problems the quality of SSS retrieval has increased steadily since the beginning of the missions. Having two independent missions working with two different technologies has been beneficial in improving the quality of the maps of SSS. For instance, intercomparison of SSS maps from the two missions is very useful for the characterization of errors and biases. The question is hence posed of how to produce SSS maps of the best quality by an appropriate combination of both missions. A simple point-wise average of SMOS and Aquarius maps leads to a small reduction of error, of order 2 on the variance (assuming that errors in SMOS and Aquarius are small). Point-wise average, however, is not capable to appropriately tackle with biases. In fact, point-wise averages only makes sense if errors are supposed to be spatially independent, and that the signals have no particular spatial structure. However, none of those two hypotheses are correct in general. As SSS maps are strongly spatially correlated, the correlation matrix can be used to reduce the noise level. This is the basis for the Optimal Interpolation (OI) method. The main drawback associate to OI is the necessity of having good prior estimates of the background term and of the spatial correlation matrices what, in turn, implies having large prior datasets of SSS maps - what we are lacking of, in fact. Taking profit of having two independent estimates of SSS, as SMOS and Aquarius, can only be profited if we include the mutual correlation matrix - also very demanding in data. Alternative ways to improve the quality of SSS maps are use singularity-based fusion methods, but in that case we need a third variable of high quality (not necessarily of the same type: high resolution SST is usually employed to this end). Having two independent variables such as the ones provided by SMOS and Aquarius allows for a different approach. If errors in SMOS and Aquarius were spatially decorrelated the optimal estimate of SSS would be the point-wise average of both variables, while the error on each of them will be given by half the difference of both SSS's, that we will call point-wise error estimate. However, the point-wise error estimate has significant two-point spatial correlations which decays like a power law with distance, what means that errors are correlated over significant distances. In this presentation, we will show a method for obtain a better estimate of SSS by jointly minimizing error correlation on SMOS and on Aquarius which improves point-wise averages and gives more spatially consistent maps. We will discuss the role of biases in the minimization and how this can be employed to enhance the intercomparisonPeer Reviewe

Inter-Comparison of SMOS and Aquarius Brightness Temperatures at L-Band over Selected Targets
No full textSMOS & Aquarius Science Workshop, 15-17 April 2013, Brest, FranceThe European Space Agency (ESA) launched the Soil Moisture and Ocean Salinity (SMOS) satellite on November 2, 2009, to globally monitoring surface soil moisture over the landmasses and salinity over the oceans. Its single payload is the first two-dimensional Microwave Imaging Radiometer with Aperture Synthesis (MIRAS), an instrument that provides multi-angular L-band measurements in the field of view (from 0† to 65°) and has full-polarimetric capabilities (measures H, V and HV polarizations). The next satellite devoted to global sea surface salinity monitoring is the Aquarius/SAC-D, which was launched on June 9, 2011, by a collaboration between the US National Aeronautics and Space Administration (NASA) and the Argentinian Comisión Nacional de Actividades Espaciales (CONAE). It includes three beam push-broom L-band real aperture radiometers and real aperture scatterometers, both full-polarimetric and feeded by the same reflector at three incidence angles (28.7°, 37.8° and 45.6° for the inner, the middle and the outer beams)Peer Reviewe
