Organized every 4 years by the International Radiation Commission, the International Radiation Symposium (IRS2008) on Current Problems in Atmospheric Radiation will be held during August 3-8, 2008, at Mabu Thermas & Resort-Congress and Exposition Center, Foz do Iguaçu, Brazil. This will be the first IRS symposium in South America, and it will be hosted jointly by the Instituto de Astronomia, Geofisica e Ciencias Atmosfericas (IAG) and Instituto de Fisica (IF) from Universidade de Sao Paulo (USP), Centro de Previsao de Tempo e Estudos Climaticos from Instituto Nacional de Pesquisas Espaciais (CPTEC/INPE), Centro de Tecnologia from Universidade Federal do Rio de Janeiro (CT/UFRJ) and Instituto de Recursos Naturais from Universidade Federal de Itajuba (IRN/UNIFEI). The IRS2009 is an opportunity to share ideas and experiences on the current problems in atmospheric radiation from theory and modeling to measurements and applications on weather and climate.
