For the past 4 years high-resolution ground layer turbulence measurements have been carried out on Cerro Tololo Inter-American Observatory (CTIO) with a lunar scintillometer. We present C_N2-profiles in the range up to 1 km and seeing statistics from fall 2007 to spring 2011. Comparisons with weather parameter links local topography to optical turbulence. The observations in Chile are compared to a ground-layer study on Mauna Kea at the Canada France Hawaii Telescope by the use of median seeing values as well as scale heights derived from the turbulence integral.
