Integrated analysis of air pollution in central West Antarctica Brazilian standalone module - Criosfera 1

Abstract
Bromwich et al. 2012 recently revealed, by meteorological observation, a linear increase in annual temperature between 1958 and 2010 by 2.4+/-1.2 degrees C, establishing central West Antarctica as one of the fastest-warming regions globally. The significant warming during austral summer reported is a matter of concern because of its implications for the state of the West Antarctic Ice Sheet and its coastal ice shelves. The project aims, through the establishment of a network of ground monitoring, the combined use of satellite data and numerical modeling of dispersion, to investigate impact of aerosols in the central West Antarctica. The present study is the molecular and elemental characterization by means of independently performed Micro-Raman and CC-SEM/EDX of the same samples of individual particles of ambient aerosol collected at the Criosfera 1 module deployed at the field site. The application of molecular spectroscopy in addition to electron microscopy and elemental microanalysis would provide intimate information regarding the nature and atmospheric processing of particles. To our knowledge, these will be the first Continuous atmospheric monitoring made in central West Antarctica.
