ICANOE and OPERA experiments at the LNGS/CNGS

We discuss two experiments ICANOE and OPERA that have been proposed within the context of long-baseline and atmospheric neutrino experiments in Europe. The joint ICANOE/OPERA program aims at further improving our understanding of the effect seen in atmospheric neutrinos. This program is based on (1) a continuation of the observation of atmospheric neutrinos with the improved technique of ICANOE/ICARUS (2) a sensitive numu->nue and numu->nutau appearance program with the accelerator neutrinos coming from CERN (CNGS) from a distance of 730 km.
