The impact of volcanic eruptions on the climate has been studied over the last decades and the role played by sulfate aerosols appears to be major. S-bearing volcanic gases are oxidized in the atmosphere into sulfate aerosols that disturb the radiative b...

In this paper, Sun-photometer multichannel measurements of aerosol optical depths (AODs) in the visible and near-infrared spectral ranges, and Ångström parameters of the plume issued from the Pacaya volcano, Guatemala, are presented for the first time. T...

The Intergovernmental Panel on Climate Change (IPCC) noted a recent 15-year period (1998–2012) when the rate of surface global warming was a factor of 4 smaller than the mean of the state-of-art climate model projections and than that observed in t...

The meteorological influences on Caribbean air chemistry are studied using in-situ, satellite and model data. Although African dust plumes join locally generated pollutants, concentrations are relatively low in the eastern Caribbean due to geographic rem...

A multidisciplinary study that includes processing of Landsat ETM+ satellite images, chemistry of gas
condensed, mineralogy and chemistry of fumarolic deposits, and fluid inclusion data from native sulphur deposits, has
been carried out in the Lastarria ...

Spectral and broad-band solar radiation measurements were made non-continuously between 1990 and 1994 at Abisko (68º 21' N, 18º 49' E), which is about 200 km north of the Arctic Circle in northern Sweden. The increase in the atmospheric turbidity due ...

Direct solar radiation measurements were used to determine the aerosol optical depth (AOD) increase associated with the presence of aerosol and large particles (ash) originating from the 28 March to 4 April 1982 El Chichón eruptions (17.5ºN, 93.3ºW; M...
