Abstract
Long-term changes in shortwave solar irradiance over Thessaloniki, Greece since 1993 are investigated, focusing on the influence of aerosols in relation to the solar zenith angle (SZA). Linear trends are computed for the entire dataset, for cloud free cases, and for different SZAs, separately for each season. The global upward trend in solar irradiance after 1990 is reconfirmed and is found to depend strongly on SZA, ranging from ~0.1% to +0.6% year−1. Finally, we report signs of a stabilization of solar irradiance at the surface after about 2000.
