polar stratospheric ozone the Arctic winters
2010/10/21
The polar stratospheric ozone loss during the Arctic winters 2004/2005–2009/2010 is investigated by using high resolution simulations from the chemical transport model Mimosa-Chim and observations fro...
Temporal variability of mineral dust concentrations over West Africa: analyses of a pluriannual monitoring from the AMMA Sahelian Dust Transect
Temporal variability mineral dust concentrations West Africa the AMMA Sahelian Dust Transect
2010/10/11
The Sahelian belt is known to be a region where atmospheric levels of suspended mineral dust are among the highest observed on Earth. In the framework of the AMMA (African Monsoon Multidisciplinary An...
Composition and temporal behavior of ambient ions in the boreal forest
ambient ions the boreal forest
2010/9/21
A recently developed atmospheric pressure interface mass spectrometer (APi-TOF) measured the negative and positive ambient ion composition at a boreal forest site. As observed in previous studies, the...
