Implementation of real-time source apportionment approaches using the ACSM–Xact–Aethalometer (AXA) setup with SoFi RT: the Athens case study [PDF]

Atmospheric Measurement Techniques
Air pollution, particularly from particulate matter (PM), poses serious public health and environmental risks, especially in urban areas. To address this, accurate source apportionment (SA) of PM is essential for effective air quality management ...

Projected environmental shifts under climate change: European trends and regional impacts [PDF]

, 2008
Potential impacts of climate change on ecosystems and the environment are generally assessed by summarizing climate change scenarios for broad regions (for example countries), or by specific modelling exercises.

Molecular-scale description of interfacial mass transfer in phase-separated aqueous secondary organic aerosol [PDF]

Atmospheric Chemistry and Physics, 2021
Liquid–liquid phase-separated (LLPS) aerosol particles are known to exhibit increased cloud condensation nuclei (CCN) activity compared to well-mixed ones due to a complex effect of low surface tension and non-ideal mixing.

Herbivores rescue diversity in warming tundra by modulating trait-dependent species losses and gains

Nature Communications, 2017
Warming can reduce plant diversity but it is unclear which species will be lost or gained under interacting global changes. Kaarlejärvi et al. manipulate temperature, herbivory and nutrients in a tundra system and find that herbivory maintains diversity ...

Contributions to local- and regional-scale formaldehyde concentrations [PDF]

Atmospheric Chemistry and Physics, 2019
Reducing ambient formaldehyde concentrations is a complex task because formaldehyde is both a primary and a secondary air pollutant, with significant anthropogenic and biogenic sources of volatile organic compound (VOC) precursor emissions.

The Environmental Impacts of the Coronavirus [PDF]

Environmental and Resource Economics, 2020
AbstractThe Covid-19 coronavirus pandemic has resulted in global lockdowns, sharply curtailing economic activity. It is a unique experiment with substantial impacts that will form the agenda for research. There are five sets of questions: the short-term impacts on emissions, the natural environment and environmental policy, including regulations and ...

Glacial geomorphology of the Chirripó National Park, Costa Rica

Journal of Maps, 2019
Several regions of tropical America show imprints of past glacial activity. These relict landforms can support the understanding of past climate conditions, such as during the Last Glacial Maximum (LGM), and the implications that these paleoclimatic ...

Climate impacts on tree growth in a Neotropical high mountain forest of the Peruvian Andes

iForest - Biogeosciences and Forestry, 2020
Global warming can jeopardize important ecosystem functions and services in sensitive Neotropical mountain areas. However, untangling the relative roles of natural climate variability pattern from current global warming trends still represent a major ...
