Assessment of rainfall variability and future change in Brazil across multiple timescales.
Rainfall variability change under global warming is a crucial issue that may have a substantial impact on society and the environment, as it can directly impact biodiversity, agriculture, and water resources. Observed precipitation trends and climate change projections over Brazil indicate that many...

Contrasting dissolved organic carbon concentrations in the Bransfield Strait, Northern Antarctic Peninsula: insights into ENSO and SAM effects.
The marine reservoir of dissolved organic carbon (DOC) is equivalent to the atmospheric carbon reservoir and represents the largest reduced carbon stock in the ocean. However, the role of DOC in the global carbon cycle is not fully understood. In this study, we analyzed the distribution of DOC in th...

Energy and CO2 fluxes over native fields of Southern Brazil through multi-objective calibration of inland model.
Land surface/ecosystem models (LSEMs) play a key role in understanding the Earths climate. They represent ecosystem dynamics by simulating fluxes occurring between the biosphere and atmosphere. However, for a correct flux simulation, it is critical to calibrate the model using robust and state-of-th...

Lightning during the COVID-19 pandemic in Brazil.
This study is concerned with the effects of a decrease in the air pollution concentration on the lightning characteristics of two large Brazilian cities. The decrease in air pollution happened from March 20, till April 02, 2020, and it was caused by the social distancing effort to contain the COVID-...

Coagulation and precipitation of cyanobacterial blooms
Eutrophication is the prime water quality issue in inland waters. Eutrophication and its key symptom, harmful cyanobacterial blooms, is expected to further increase in the future, which highlights the importance of managing the issue. The reduction of external nutrient load is crucial but might not ...

Hierarchical color similarity metrics for step-wise application on sky monitoring surface cameras.
Digital cameras deployed on the surface are frequently used for monitoring atmospheric conditions. Several methods were developed to use the images for synoptic observations, cloud assessments, validation of satellite models, short term forecasting and so on. However, there are some restrictions not...

Fatores associados a distribuição da temperatura das superfícies em área urbana: zonas climáticas locais e suas características espectrais
Global warming makes urban fabric benchmarking necessary for the development of policies that promote urban heat resilience. This research is aimed at identifying urban fabric patterns, which can promote the negative feedback of the urban climate system naturally. The method includes the use of Land...
