Radiative transfer model calculations of solar fluxes during cloud free periods often show considerable discrepancies with surface radiation observations. Many efforts have been undertaken to explain the differences between modeled and observed shortwave downward radiation (SDR). In this study, MODTRAN4v3r1TM (designed later simply as MODTRANTM) was used for model simulations and compared with high quality radiation observations of the Baseline Surface Radiation Network (BSRN) site at Payerne, Switzerland. Results are presented for cloud free shortwave downward radiation calculations. The median differences of modeled minus observed global SDR are small (
