Modern human society is facing various risks of environmental changes. Among such risks, we, trilateral international collaboration team consisting of Argentine, Chilean, and Japanese researchers, focuses on UV exposure related to ozone depletion and aerosol air-pollution especially related to the volcanic eruptions under the SATREPS program promoted by JST and JICA. The South-Patagonian region in South America is the southernmost habitable area in the world, and the inhabitant of this region directly suffers the influence of ozone hole that sometimes overpasses the region. In addition, volcanic ashes spread from the Andes volcanoes cause serious damages on agriculture, live stocks, forestry, tourism, and daily life near the volcanoes and make traffic jams of airlines over much larger area. However, the present monitoring system for ozone/UV and aerosols in the South American continent lags significantly behind the northern hemisphere such as Europe and US. To overcome this situation, we are constructing new ground-based observing network of ozone/UV and aerosols to detect the risks for the local habitant, and establishing a communication network distributing near-real-time risk information and near-future forecasts based on model calculations. We call the new observing and data distribution system as South American Environmental Risk Management Network, SAVER-Net. SAVER-Net observing sites consists of 9 aerosol lidar monitoring stations and UV photometers distributed over Argentinean and Chilean territories, and a multi-instrumental comprehensive observational base for monitoring of ozone by using DIAL, mm-wave spectrometer, Brewer spectrometer, and ozonesonde in a city at the southern end of the South American continent, Rio Gallegos. The data acquisition, analysis, and distribution center will be also established in collaboration with relevant ministries and organizations in Argentina and Chile. In my presentation, I will give an overview of this project and brief summary of progress situation at the mid-point of the project period as an introduction of subsequent presentations of individual topics.
