Particles of soot from forest fires are transported by the wind, reaching distant locations and being deposited on the soil through precipitation, which clears the atmosphere, taking suspended particulate matter into its drops. The general circulation over South America indicates the possibility of soot from forest fires in the Amazon and Pantanal to be transported to southern Brazil. The event called “black rain” was observed in the period from 11 to 13 September 2020 at São Francisco de Assis City, in Rio Grande do Sul State (RS), and so this work aims to analyze if there were any anomalies of the flow that favored the occurrence of this event, given that there was a large number of fires in this period. Through ERA5 reanalysis data and GOES-16 satellite images, it was observed that on the three days under study low-level flow to the south of Brazil was more intense than normal, with the Low Level Jet occurrences, and on days 12 and 13 such flow to the south was also observed at 500 hPa. The precipitation was due to the instability of an extended trough from the Northwestern Argentinean Low. Thus, it is believed that there was a contribution from circulation at low and mid levels in the occurrence of black rain over RS.

Devido sua grande importância, o Pantanal é objeto de estudos de trabalhos que visam conhecer e proteger sua biodiversidade. Como instrumento indispensável, o Sensoriamento Remoto surge como uma ferramenta ideal para o mapeamento, identificação de queimadas, desmatamento e estudos climáticos. Dentre as variáveis estimadas pelos sensores orbitais, a temperatura da superfície é a menos explorada. Estudos que são conduzidos para validação da temperatura da superfície por meio de sensores orbitais e de estações meteorológicas no bioma Pantanal são escassos. Diante disso, este trabalho visou analisar a dinâmica da temperatura da superfície em uma unidade de conservação no norte do Pantanal a partir de imagens adquiridas do satélite Landsat 8. O estudo foi realizado em uma torre micrometeorológica, localizada entre os municípios de Cuiabá e Santo Antônio de Leverger - MT, situada na encosta de uma unidade de conservação, denominada Monumento Natural Morro de Santo Antônio. Para validação da temperatura da superfície, foram adquiridas imagens do satélite Landsat 8 fornecidos pela USGS. Resultados encontrados nesse trabalho demonstraram o uso das bandas termais do Landsat 8 no norte do Pantanal mato-grossense na discriminação de diferentes alvos na superfície. A análise parcial de cada banda do sensor TIRS demonstrou valores mais elevados na banda 10. A análise estatística dos dados indica que as maiores correlações da temperatura medida na torre meteorológica foram constatadas com a média das bandas termais do satélite Landsat 8. A análise de variância demonstrou que houve diferença significativa entre as médias das temperaturas medida e estimada.Palavras-chaves: banda termal, sensor orbital, Pantanal. Surface temperature evaluation in the Pantanal Mato Grosso by Remote Sensing A B S T R A C TDue to its great importance, the Pantanal is the object of studies that aim to know and protect its biodiversity. As an indispensable tool, Remote Sensing emerges as an ideal tool for the mapping, identification of fires, deforestation and climatic studies. Among the variables estimated by the orbital sensors, the surface temperature is the least explored. Studies that are conducted for surface temperature validation by orbital sensors and meteorological stations in the Pantanal biome are scarce. The study was carried out in a micrometeorological tower, located between the municipalities of Cuiabá and Santo Antônio, located on the slope of a conservation unit, called Natural Monument Morro de Santo Antônio. To validate the surface temperature, images of the Landsat 8 satellite provided by the USGS were acquired. Results obtained in this work demonstrated the use of the Landsat 8 thermal bands in the northern Pantanal of Mato Grosso in the discrimination of different surface targets. The partial analysis of each TIRS sensor band showed higher values in the 10 band. Statistical analysis of the data indicates that the highest correlations of the temperature measured in the meteorological tower were verified with the average of the thermal bands of the satellite Landsat 8. The analysis of variance showed that there was a significant difference between the measured and estimated temperatures.Keywords: thermal band, orbital sensor, Pantanal.

“…To contemplate the variations in the time-space plan of the Pantanal, studies on the dynamics of land use change and occupation are of great importance (Leite and Brito, 2012;Miranda et al, 2018). The monitoring of the dynamics of the biophysical parameters of the terrestrial surface allows to diagnose natural and anthropic alterations in the landscape of an ecosystem (Cunha et al, 2012).…”

Among other biomes found in the Brazilian territory, the Pantanal has been characterized by the smallest percentage of protected areas in the country (4%, belonging to the states of Mato Grosso and Mato Grosso do Sul), behind only the Pampa biomes (3.5%) and (1.5%), where the Amazon biome corresponds to 26.2%, Cerrado to 7.9%, Atlantic Forest to 7.8% and Caatinga to 7.3% (Gurgel et al., 2009, Vigano et al., 2018). Floodplain areas are among the most fragile and sensitive ecosystems on the planet, and the Mato Grosso Pantanal is one of the greatest examples, with wide hydrological complexity, generating in scientists the need to know better the dynamics of hydrological cycles and their influence on local vegetation (Novais et al., 2018).
