A partir del 2012 se instalaron 4 estaciones de monitoreo atmosférico dedicadas a la detección de aerosoles en suspensión, básicamente provenientes de cenizas volcánicas y polvo en la Patagonia en el marco de un proyecto especial del Ministerio de Defensa. Estas estaciones tienen entre sus instrumentos fotómetros solares CIMEL que fueron integrados a la red mundial AERONET de NASA. En este trabajo se presenta un análisis estadístico de los datos obtenidos en las estaciones AERONET de: CEILAP-Bariloche, CEILAP-Comodoro, CEILAP-Neuquén, CEILAP-RG que forman parte de las nuevas estaciones instaladas por el proyecto y la estación de Trelew, instalada previamente en el 2005, para determinar el tipo de aerosoles que caracteriza la región patagónica, su comportamiento y variabilidad.

Two main decisions were made in Argentina to mitigate the impact of the recent volcanic activity in de country basically affected by the presence of volcanic ash in the air and deposited over the Argentinean territory. The first one was to create a risk management commission were this risk between others were studied, and second to develop new ground based remote sensing technologies to be able to identify and inform the risk close to the airports. In addition the Japanese government program for Science and Technology joint Research Partnership between Argentina, Chile and Japan for Sustainable Development (SATREPS) accepted to fund this cooperation due to the potential future utilization of the research outcomes to the benefit of the society. This work present the actual achievements and expected advance of these projects that try to joint efforts between national and international agencies as well as countries on behalf of a better understanding of the risks and a joint collaboration on the mitigation of suspended ashes impact over the aerial navigation.
