Cirrus clouds observation in Santa Maria, Rio Grande do Sul during the experiment Chuva - Sul.

Cirrus clouds are an interesting point in the research of the atmosphere due their behavior and the effect on the earth radiation budget. They can affect the atmospheric radiation budget by reflecting the incoming solar radiation and absorbing the outgoing terrestrial radiation. Also, this cloud type is involved in the dehydration of the upper troposphere and lower stratosphere. So, it is interesting to increment the measurements of this type of clouds from the ground. During November and December 2012, through the CHUVA-SUL campaign, measurements with lidar in Santa Maria, Rio Grande do Sul were conducted. The system installed in Santa Maria site (29.8 °S; 53.7 °W, 100 m asl) was a single elastic-backscatter lidar using the wavelength of 532 nm. Some days with cirrus clouds lidar measurements were detected. Four days with presence of cirrus cloud are showed in the present study. These days, 7, 8, 19 and 28 November 2012, was selected due the persistence of cirrus clouds over many hours. The raw retrieval lidar signals and inverted backscatter coefficient profiles were analyzed for the selected days. Base and top height was obtained by analysis of raw signal and backscatter coefficient. Extinction coefficient profiles were obtained by the assumption of the lidar ratio. Cirrus cloud optical depth (COD) values were calculated, from the integration of the extinction coefficient between the base and top altitudes of the cirrus clouds.

A política fundiária do governo Olívio Dutra no Rio Grande do Sul - Brasil (1999-2002): diretrizes, dinâmica política e resultados atingidos

This paper has as objective to analyze the foundry work politics made by the Olívio Dutra's government in the state of Rio Grande do Sul-Brazil, being taken into account their guidelines, the dynamics of the political struggle promoted between the social leaders from the rural area and the achieved global results. This government's freshness is related to the fact of it was being sustained and supported by a coalition of left wing parties and by a group of social movements and also by syndical entities of the field, which was decisive in the presentation of an antagonistic program to the neoliberal politics on energy in a national extent. Hence this government became committed in adopting an own foundry work politics, being opposed to the program of market land reform extolled by Cardoso's government, in national wide. Therefore, the results presented along the article demonstrate that in spite of the assumed commitments and, in face of legal, institutional and economical limitations and also its existent politics, the space of the state governments' performance can only be thought about its complemental character on the federal government's actions.

Ocupaçâo, valorizaçâo e comércio de terras no norte do Rio Grande do Sul - séculos 19 e 20

This article focuses on some aspects of the agrarian history of Soledade, a town in the north of the state of Rio Grande do Sul, southern Brazil. Our aim is to understand how this area was in many ways affected by the Land Law of 1850, particularly in economic and social terms. Population growth, arrival of European immigrants and increasing privatization of the commons contributed for the increasing of land prices in the region during the second half of the 19 th century. Understanding this situation as a great opportunity to make money, some landowners, directly or through a colonization company, allotted and sold the land they had previously acquired through the Land Law of 1850
