Climatic characteristics of the 2010-2016 drought in the semiarid Northeast Brazil region.
This study discusses the climatological aspects of the most severe drought ever recorded in the semiarid region Northeast Brazil. Droughts are recurrent in the region and while El Nino has driven some of these events others are more dependent on the tropical North Atlantic sea surface temperature fi...

Challenges for a disaster prevention schedule at historic sites: the case of Sao Luiz do Paraitinga, SP.
Disasters have been affecting several municipalities listed as cultural heritage sites, as highlighted by the media stories of the 2010 January floods in Sao Luiz do Paraitinga city, Sao Paulo state. This paper shared some findings related to two phases of research. The first phase occurred from Jan...

A review of studies on participatory early warning systems (P-EWS): pathways to support citizen science initiatives.
Context: Global environmental change and disasters pose several challenges to governments, society and science. These challenges occurred in social contexts were information and communication technologies can be used to share data and information, engaging citizen scientists in multidirectional and ...

Climate change projections over three metropolitan regions in Southeast Brazil using the non-hydrostatic Eta regional climate model at 5-km resolution.
The objective of this work is to assess changes in three metropolitan regions of Southeast Brazil (Rio de Janeiro, São Paulo, and Santos) based on the projections produced by the Eta Regional Climate Model (RCM) at very high spatial resolution, 5 km. The region, which is densely populated and extre...

Erratum to: climate change projections over three metropolitan regions in Southeast Brazil using the non-hydrostatic Eta regional climate model at 5-km resolution.
In Lyra et al. (2017), regarding the sentence in page 4, section 2.4, first column, second paragraph: The MRRJ is located in the state of Rio de Janeiro.This area of approximately 5 million km2 with a population of almost 12 million people (CEPERJ 2010) is the second largest urban agglomeration in B...

Analysis of intra-day solar irradiance variability in different Brazilian climate zones.
One of the main barriers to increasing the solar energy share is its intermittency. Solar energys large variability in different timescales is driven by natural solar astronomical cycles and weather. Ground-based measurements are important for evaluating variability at high temporal resolutions, but...

Comparison of methodologies for cloud cover estimation in Brazil: a case study.
Clouds are the major modulator of the shortwave and longwave radiation components of the Earth's energy balance and, as such, help to regulate the planet's temperature. In the energy sector, clouds are a source of instability in the generation of energy using solar technologies. This study aims at c...

Limiting the high impacts of Amazon forest dieback with no-regrets science and policy action.
Large uncertainties still dominate the hypothesis of an abrupt large-scale shift of the Amazon forest caused by climate change [Amazonian forest dieback (AFD)] even though observational evidence shows the forest and regional climate changing. Here, we assess whether mitigation or adaptation action s...

International organizations, advocacy coalitions, and domestication of global norms: debates on climate change in Canada, the US, Brazil, and India.
National climate policies are shaped by international organizations (IOs) and global norms. Drawing from World Society Theory and the Advocacy Coalition Framework (ACF), we develop two related arguments: (1) one way in which IOs can influence national climate policy is through their engagement in ma...

Widespread reduction in sun-induced fluorescence from the Amazon during the 2015/2016 El Niño.
The tropical carbon balance dominates year-to-year variations in the CO2 exchange with the atmosphere through photosynthesis, respiration and fires. Because of its high correlation with gross primary productivity (GPP), observations of sun-induced fluorescence (SIF) are of great interest. We develop...

Future climate change scenarios in Central America at high spatial resolution.
The objective of this work is to assess the downscaling projections of climate change over Central America at 8-km resolution using the Eta Regional Climate Model, driven by the HadGEM2-ES simulations of RCP4.5 emission scenario. The narrow characteristic of continent supports the use of numerical s...

Tropical land carbon cycle responses to 2015/16 El Nino as recorded by atmospheric greenhouse gas and remote sensing data.
The outstanding tropical land climate characteristic over the past decades is rapid warming, with no significant large-scale precipitation trends. This warming is expected to continue but the effects on tropical vegetation are unknown. El Nino-related heat peaks may provide a test bed for a future h...
