Study and evaluation of atmospheric pollution in Spain: necessary measures arising from the EC Directive on PM10 and PM2.5 particles in the Ceramic industry

Publication Type: Academic Journal

Source(s): Boletín de la Sociedad Española de Cerámica y Vidrio, Vol 39, Iss 1, Pp 135-148 (2000)

Abstract: The European Commission Directive, 1999/30/EC, approved on the 22nd of April 1999, on atmospheric particles establishes a standard that is more stringent than the current one. This Directive proposes the monitoring of particles lower than 10 μm (PM10, ...

Absorption enhancement of black carbon particles in a Mediterranean city and countryside: effect of particulate matter chemistry, ageing and trend analysis

Publication Type: Academic Journal

Source(s): Atmospheric Chemistry and Physics, Vol 22, Pp 8439-8456 (2022)

Abstract: Black carbon (BC) is recognized as the most important warming agent among atmospheric aerosol particles. The absorption efficiency of pure BC is rather well-known, nevertheless the mixing of BC with other aerosol particles can enhance the BC light abso...

Determination of the multiple-scattering correction factor and its cross-sensitivity to scattering and wavelength dependence for different AE33 Aethalometer filter tapes: a multi-instrumental approach

Publication Type: Academic Journal

Source(s): Atmospheric Measurement Techniques, Vol 14, Pp 6335-6355 (2021)

Abstract: Providing reliable observations of aerosol particles' absorption properties at spatial and temporal resolutions suited to climate models is of utter importance to better understand the effects that atmospheric particles have on climate. Nowadays, one o...

A phenomenology of new particle formation (NPF) at 13 European sites

Publication Type: Academic Journal

Source(s): Atmospheric Chemistry and Physics, Vol 21, Pp 11905-11925 (2021)

Abstract: New particle formation (NPF) events occur almost everywhere in the world and can play an important role as a particle source. The frequency and characteristics of NPF events vary spatially, and this variability is yet to be fully understood. In the pre...

Increase in secondary organic aerosol in an urban environment

Publication Type: Academic Journal

Source(s): Atmospheric Chemistry and Physics, Vol 21, Pp 8323-8339 (2021)

Abstract: The evolution of fine aerosol (PM1) species as well as the contribution of potential sources to the total organic aerosol (OA) at an urban background site in Barcelona, in the western Mediterranean basin (WMB) was investigated. For this purpose, a quad...

The case of a southern European glacier which survived Roman and medieval warm periods but is disappearing under recent warming

Publication Type: Academic Journal

Source(s): The Cryosphere, Vol 15, Pp 1157-1172 (2021)

Abstract: Mountain glaciers have generally experienced an accelerated retreat over the last 3 decades as a rapid response to current global warming. However, the response to previous warm periods in the Holocene is not well-described for glaciers of the southern...

The effect of meteorological conditions and atmospheric composition in the occurrence and development of new particle formation (NPF) events in Europe

Publication Type: Academic Journal

Source(s): Atmospheric Chemistry and Physics, Vol 21, Pp 3345-3370 (2021)

Abstract: Although new particle formation (NPF) events have been studied extensively for some decades, the mechanisms that drive their occurrence and development are yet to be fully elucidated. Laboratory studies have done much to elucidate the molecular process...

Aircraft vertical profiles during summertime regional and Saharan dust scenarios over the north-western Mediterranean basin: aerosol optical and physical properties

Publication Type: Academic Journal

Source(s): Atmospheric Chemistry and Physics, Vol 21, Pp 431-455 (2021)

Abstract: Accurate measurements of the horizontal and vertical distribution of atmospheric aerosol particle optical properties are key for a better understanding of their impact on the climate. Here we present the results of a measurement campaign based on instr...

Molecular insights into new particle formation in Barcelona, Spain

Publication Type: Academic Journal

Source(s): Atmospheric Chemistry and Physics, Vol 20, Pp 10029-10045 (2020)

Abstract: Atmospheric aerosols contribute some of the greatest uncertainties to estimates of global radiative forcing and have significant effects on human health. New particle formation (NPF) is the process by which new aerosols of sub-2 nm diameter form from g...
