Revista Brasileira De Geografia Fisica, 2025
A Caatinga é um bioma altamente suscetível à degradação, um processo que pode levar à desertificação. Portanto, entender a dinâmica de áreas desse bioma que passaram por degradação, resultando em perda de produtividade, mas que conseguiram se recuperar, é de extrema importância. Assim, o objetivo deste estudo foi analisar os padrões sazonais e anuais dos componentes do balanço de energia e das trocas de CO2 em uma Caatinga regenerada na Paraíba, ao longo dos anos de 2014 e 2016. Ambos os anos apresentaram valores mais elevados de H no período seco. Por outro lado, o LE variou de 60 a 10 W/m² em 2014 e de 40 a 60 W/m² em 2016, com os maiores valores observados durante os períodos de maior precipitação, devido à maior disponibilidade de água. Foi observado que a dinâmica da produtividade primária líquida (GPP), respiração do ecossistema (Reco) e troca líquida de CO2 no ecossistema (NEE) variaram dependendo da magnitude e distribuição das chuvas e, como consequência, da variabilidade da cobertura vegetal. O NEE acumulado anual não apresentou diferença significativa (p > 0,01) entre os anos de 2014 (-1.476 g C m-²) e 2016 (-1.436 g C m-²). A Caatinga atuou como um sumidouro de carbono atmosférico nos anos de 2014 e 2016 e a dinâmica do balanço de carbono está associada à sazonalidade das chuvas.

Assessment of irrigation in arid and semiarid regions is imperative to ensure the sustainable use of limited water resources and guarantee food production. Therefore, this study aimed to assess actual evapotranspiration – ETa derived from the Surface Energy Balance Algorithm for Land – SEBAL model with and without satellite image fusion as input of a soil water balance in a pilot area of sugarcane in the semiarid region of Brazil. A fusion of Landsat sensors’ and Moderate Resolution Imaging Spectroradiometer – MODIS’ images was completed through a Spatial and Temporal Adaptive Reflectance Fusion Model – STARFM script developed using cloud computing, and its performance in estimating key variables for the radiation balance was evaluated. ETa and irrigation were daily estimated between June, 2015 and May, 2016 by combining STARFM with SEBAL and evaluated according to the Bowen ratio technique and irrigation data. In addition, one-minute surface meteorological elements at the satellite overpass times were used. STARFM performed well with RMSE of 17.00 W m−2, 2.28 K, 0.07, and 0.01 for Rn, Ts, NDVI, and albedo, respectively. The metrics employed to evaluate ETa estimates indicated that the SEBAL+STARFM has low mean errors (PBIAS = −2.75% and RMSE = 0.97 mm d−1 and 16.66 mm month−1) and high coefficient of determination (0.87 for daily ETa–ET24, and 0.91 for monthly ETa), in comparison with SEBAL using Landsat-only images (PBIAS = −5.25%, RMSE = 0.97 mm d−1 and 17.66 mm month−1, r² = 0.92). Adding fused images resulted in a better fit of the estimated cumulative ET24 curve to the measured ET24. The water balance indicated that the cultivated cane suffered water stress, which was better represented by estimates using the ET24 curve with the addition of fused images than Landsat images alone. Although this increase in temporal resolution of the estimated ET24 data indicated a greater water consumption, it informs a quantity that would be sufficient to meet the water demand of the crops.

Remote Sensing, 2022
The Caatinga is the largest nucleus of Seasonally Dry Tropical Forests (SDTF) in the Neotropics. The leafing patterns of SDTF vegetation are adapted to the current environmental and climate variability, but the impacts of climate change tend to alter plants’ phenology. Thus, it is necessary to characterise phenological parameters and evaluate the relationship between vegetation and environmental drivers. From this information, it is possible to identify the dominant forces in the environment that trigger the phenological dynamics of the Caatinga. In this way, remote sensing represents an essential tool to investigate the phenology of vegetation, particularly as it has a long series of vegetation monitoring and allows relationships with different environmental drivers. This study has two objectives: (i) estimate phenological parameters using an Enhanced Vegetation Index (EVI) time-series over 20 years, and (ii) characterise the relationship between phenologic dynamics and environmental drivers. TIMESAT software was used to determine four phenological parameters: Start Of Season (SOS), End Of Season (EOS), Length Of Season (LOS), and Amplitude (AMPL). Boxplots, Pearson’s, and partial correlation coefficients defined relationships between phenologic dynamics and environmental drivers. The non-parametric test of Fligner–Killeen was used to test the interannual variability in SOS and EOS. Our results show that the seasonality of vegetation growth in the Caatinga was different in the three experimental sites. The SOS was the parameter that presented the greatest variability in the days of the year (DOY), reaching a variation of 117 days. The sites with the highest SOS variability are the same ones that showed the lowest EOS variation. In addition, the values of LOS and AMPL are directly linked to the annual distribution of rainfall, and the longer the rainy season, the greater their values are. The variability of the natural cycles of the environmental drivers that regulate the ecosystem’s phenology and the influence on the Caatinga’s natural dynamics indicated a greater sensitivity of the phenologic dynamics to water availability, with precipitation being the limiting factor of the phenologic dynamics. Highlights: The EVI time series was efficient in estimating phenological parameters. The high variability of the start of season (SOS) occurred in sites with low variability of end of the season (EOS) and vice versa. The precipitation and water deficit presented a higher correlation coefficient with phenological dynamics. Length of Season (LOS) and amplitude (AMPL) are directly linked to the annual distribution of rainfall.

Essa mudança é uma das responsáveis pelas variações no saldo de radiação (Rn), pois afetam a troca de energia entre a superfície e a atmosfera. O objetivo foi estimar o Rn em uma área de açaí irrigado na Amazônia Oriental. Foram utilizadas imagens do satélite Landsat 8, do dia sequencial do ano (DSA) 151/2018 e DSA 241/2019, referente às órbitas/pontos 222/61 e 223/61, respectivamente. O Rn foi obtido por meio do algoritmo Surface Energy Balance Algorithm for Land – SEBAL, que se fundamenta na radiância dos canais reflexivos e termal do sensor. Os resultados (sensor x superfície) mostraram-se satisfatórios com valores de erro absoluto médio (EAM) iguais a 4,92 W/m2 e 15,66 W/m2, erro relativo médio (ERM) iguais a 0,98 % e 3,4 % para DSA 151 e o DSA 241, respectivamente. Observou-se a capacidade do SEBAL em diferenciar tipos de coberturas do solo, o que proporcionou elaborar a distribuição espacial do Rn na cena analisada e no plantio de açaí, demostrando assim, a sensibilidade do modelo e a importância da variabilidade espacial existente na área, essas informações podem auxiliar as tomadas de decisões quanto ao manejo de irrigação.

ESTIMATION OF THE RADIATION BALANCE OF IRRIGATED AÇAÍ THROUGH REMOTE SENSING IN EAST AMAZONIA 2 ABSTRACT Many areas in the Amazon have been modified, altering the energy exchanges in this environment. This change is a factor responsible for variations in the radiation balance (Rn), as they affect the energy exchange between the surface and the atmosphere. The objective was to estimate the Rn in an açaí irrigated area in Eastern Amazon. Landsat 8 satellite images of the sequential day of the year (DSA) 151/2018 and DSA 241/2019, referring to orbits/points: 222/61 and 223/61, respectively, were used. The Rn was obtained through the Surface Energy Balance Algorithm for Land - SEBAL algorithm, which is based on the radiance of the reflective and thermal bands of the sensor. The results (sensor x surface) were satisfactory with mean absolute error (EAM) values equal to 4.92 W/m2 and 15.66 W/m2, mean relative error (ERM) equal to 0.98% and 3.4% for DSA 151 and DSA 241, respectively. SEBAL's ability to differentiate types of land cover was observed, which provided the elaboration of the spatial distribution of Rn in the analyzed scene and in the açaí planting, so demonstrating the sensitivity of the model and the importance of spatial variability in the area, this information can help in decision-making regarding irrigation management. Keywords: sebal, spatial variability, landsat 8.

Los ecosistemas forestales, como el bosque atlántico en América del sur, han sido removidos para dar lugar a actividades agropecuarias y asentamiento humanos. Tal situación estaría ocasionando cambios en la absorción de la energía solar en la superficie terrestre, lo que modifica el consumo de radiación neta, que, a su vez, puede influir en la temperatura del aire. Por consiguiente, esta investigación tuvo como objetivo evaluar las alteraciones de la radiación neta en la cuenca hidrográfica de Sorocaba, para analizar cómo el cambio de bosque atlántico por áreas agropecuarias y construcciones antrópicas impacta en la radiación neta y la repercusión que podría estar ocasionando en la regulación del clima local. Para esto fue determinado el balance de radiación en la cuenca y sus componentes biofísicos (NDVI, temperatura superficial, albedo y radiación emitida), por medio del modelo SEBAL, utilizando imágenes OLI/TIRS–Landsat 8 y ASTER(GDEM). Los resultados revelaron que las zonas construidas, seguidas por las agropecuarias, en comparación con la de bosque atlántico, presentan valores de albedo y temperatura superficial superiores, y, consecuentemente, mayores flujos de calor emitido a la atmósfera en forma de radiación infrarroja. Por consiguiente, se generó menores consumo de radiación neta, cuya media para las áreas boscosas, agrícolas, con pastos, suelos desnudos y construidas fue de 712,40Wm-2, 669,40Wm-2, 629,90Wm-2, 616,60Wm-2 y 524,40Wm-2, respectivamente. Así, la deforestación en la cuenca ocasionó que disminuyera la radiación neta y se emita más calor a la atmósfera, lo que favorece el efecto invernadero (principal causante del calentamiento global), en detrimento de poder regular la temperatura del aire.
