Land Surface Temperature continuous time series from SSM/I passive microwave radiometers, over northern latitudes (Latitudes > 45°N), during summer snow free period (2000-2011), with links to NetCDF files

Remote sensing instruments are key players to map land surface temperature (LST) at large temporal and spatial scales. In this paper, we present how we combine passive microwave and thermal infrared data to estimate LST during summer snow-free periods over northern high latitudes. The methodology is based on the SSM/I-SSMIS 37 GHz measurements at both vertical and horizontal polarizations on a 25 km × 25 km grid size. LST is retrieved from brightness temperatures introducing an empirical linear relationship between emissivities at both polarizations as described in Royer and Poirier (2010). This relationship is calibrated at pixel scale, using cloud-free independent LST data from MODIS instruments. The SSM/I-SSMIS and MODIS data are synchronized by fitting a diurnal cycle model built on skin temperature reanalysis provided by the European Centre for Medium-Range Weather Forecasts (ECMWF). The resulting temperature dataset is provided at 25 km scale and at an hourly time step during the ten-year analysis period (2000-2011). This new product was locally evaluated at five experimental sites of the EU-PAGE21 project against air temperature measurements and meteorological model reanalysis, and compared to the MODIS LST product at both local and circumpolar scale. The results giving a mean RMSE of the order of 2.2 K demonstrate the usefulness of the microwave product, which is unaffected by clouds as opposed to thermal infrared products and offers a better resolution compared to model reanalysis.

Environmental context of all samples from the Tara Oceans Expedition (2009-2013), about mesoscale features

The Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set provides environmental context to all samples from the Tara Oceans Expedition (2009-2013), about mesoscale features related to the sampling date, time and location. Includes calculated averages of mesaurements made concurrently at the sampling location and depth, and calculated averages from climatologies (AMODIS, VGPM) and satellite products.

The business management strategy of Iran's large apparel firms : overview of results from a questionnaire survey and interviews 2009-2011

This paper is an overview of the results from a questionnaire survey and subsequent supplementary interviews of Iran's large apparel firms conducted by the author in 2009-2011. Most of the large apparel firms in Iran are based in Tehran and have been in business for some twenty years. They have a solid business with regular customers, but in general have hesitated to expand the size of their firms. Following the relaxation of restrictions on the procurement of raw materials that existed in the 1990s, the results of survey and interviews show that the firms have developed new channels of procurement although they depend to a considerable degree on imported raw materials and machinery. They have managed to maintain their level of output even with the rapid increase in imports since 2000, although the number of firms has decreased. Low-priced Chinese products have basically not been their rivals; instead, the inflow of foreign name-brand products have hit them heavily.

TRANSPARÊNCIA PÚBLICA E PARLAMENTO ELETRÔNICO: A reforma do Poder Judiciário no portal do Senado Federal 2000-2004

A Constituição de 1988 e leis subsequentes determinam que o Estado preste informações aos cidadãos e favoreça a sua participação nas questões públicas trata-se do princípio legal da Transparência Administrativa, que compreende os seguintes subprincípios: (1) Informação; (2) Motivação e, o mais importante, (3) Participação e interatividade cidadãs. O alto investimento na Comunicação Estatal e os avanços tecnológicos, por si sós, não garantem a prática da transparência pública ou da democratização da informação. Sob uma perspectiva multidisciplinar, esta pesquisa discutiu o princípio legal de Transparência Administrativa, comparativamente à Teoria da Comunicação, com o objetivo de propor um conceito de Comunicação Estatal que, de fato, corresponda aos ideais e à ética necessários à Comunicação Pública. Para o desenvolvimento deste estudo foi investigada a relação da comunicação com o grau de transparência alcançado no portal do Senado Federal. O estudo analisou a tramitação da reforma do Poder Judiciário no período de 2000 a 2004, tendo em vista os três subprincípios legais da Transparência Pública. A análise contemplou, no portal do Senado, o trabalho jornalístico e a disponibilização on-line de textos digitais referentes a documentos originais, tais como atas públicas e notas taquigráficas. A metodologia, de enfoques quantitativo e qualitativo, teve como instrumento principal a Nova Retórica, para análise de matérias jornalísticas e textos documentais. Para averiguação da interatividade conceito que fundamenta o ideal de justiça , foram estabelecidos critérios analíticos a partir da intersecção entre os conceitos de transparência e E-parliaments. Constatou-se que o portal do Senado, no referente à reforma da Justiça, alcançou graus de transparência, atendendo mais aos subprincípios da informação e da motivação em detrimento aos da participação e interatividade cidadãs.(AU)
