The Meditteranean Intensive Oxidant Study (MINOS) took place in 2001 on the Greek island of Crete. The data (http://www-abc-asia.ucsd.edu/data_archive/minos_data/) was collected at the Finokalia sampling station located in the north-eastern part of Crete (35.34°N, 25.67°E, elevation - 265m). The directly measured aerosol and radiometric quantities included aerosol optical depth, total and diffuse broadband radiative fluxes, direct fluxes, and diffuse and total radiation fluxes in the visible region.
