Tropospheric ozone levels around urban and suburban areas at Europe North America had increased during 80’s–90’s, until the application of NO x reduction strategies. However, as it was expected, this depletion not proportional to emissions reduction. On other hand, rural show different trends, with peaks average increments; evolution could be explained by either emission changes or climate variability in a region. In work, trends tropospheric episodes sites northwest Iberian Peninsula were...
Armed conflict can endanger natural resources through several channels such as direct predation from fighting groups, but it may also help preserve ecosystems by dissuading extractive economic activities the fear of extortion. The effect on deforestation is thus an empirical question. This paper studies forest cover Colombia’s recent peace negotiation between government and FARC insurgency. Using yearly data satellite images a difference-in-differences identification strategy, we show that...
Air quality modelling requires accurate and detailed meteorological modelling, depending on the scale of problem. As a consequence, comparison results against both surface aloft observations is highly recommended. In this work, CALMET diagnostic model (at three different horizontal resolutions) nested to WRF simulations (3 km resolution) over complex terrain coastal domain at NW Spain. Both are compared upper-air measurements, showing that PBL depth better than results. About comparison,...
The application of CALMET/CALPUFF modelling system is well known, and several validation tests were performed until now; however, most them based on experiments with a large compilation surface aloft meteorological measurements, not always available. Also, the use an operational smokestack as tracer source so usual. In this work, CALPUFF model applied to simulate local dispersion SO 2 (as tracer) from (with four parallel liners) coal-fired power plant emitting tracer), considering both...
CALMET/CALPUFF modeling system is frequently used in the study of atmospheric processes and pollution, several validation tests were performed until now; nevertheless, most them based on experiments with a large compilation surface aloft meteorological measurements, rarely available. At same time, use operational smokestack as tracer/pollutant source not usual. In this work, first CALMET diagnostic model nested to WRF prognostic simulations (3x3 km2 horizontal resolution) over complex...
The COVID-19 pandemic and associated government responses halted economic activity across the world. environment benefited from reduced pollution in urban areas. However, there is no evidence on pandemic's environmental effect away cities, specifically deforestation. \textit{A priori}, unclear: deforestation might decrease with restrictions activity. But it increase, given drying up of alternative income sources. I combine bi-weekly data 70 countries covering entire world's tropical forest...
Deforestation is a large contributor to climate change. Controlling deforestation difficult, especially because there are 484 million of hectares forest that community owned. In principle this arrangement could lead tragedy the "commons", however be economies scale on monitoring outsiders' deforestation. We study effect communal titling in Colombia, using difference-in-differences strategy at border. find decreased only small titles, even when control area national parks. This suggests can...
Different operational air quality forecasts (ESSEM Cost Action 0602) are currently available in Europe. However, most of them not suitable for regional application and, also, their coarse outputs do fit well with management needs. In this work, PRESAXIO modelling system is validated and applied over Galicia (NW Spain), including WRF CHIMERE models. validation done by comparison surface meteorological measurements; applies DELTA tool AirBase data. applications include an forecast, design a...
Almost a third of the world's forest area is communally managed. In principle, this arrangement could lead to 'tragedy commons' and therefore more deforestation. But it may be easier monitor outsiders' deforestation land owned by community rather than an individual. We present theoretical framework examine these trade-offs empirically study effect communal titling on in Colombia. Our empirical approach uses differences-in-discontinuities strategy that compares areas just outside inside...
Abstract The COVID-19 pandemic and government responses led to a halt in economic activity. While this reduced pollution urban areas, its effect on deforestation areas outside of cities is unclear. Deforestation may have decreased due the restrictions activity, but, it increased drying up alternative income sources. We analyzed bi-weekly data tropical forests worldwide relation dates when different countries implemented lockdown restrictions. Our analysis found that while lockdowns did...
