Solar radiation presents a long-term cycle of 80-90 years length called Gleissberg cycle. The length of the sunspot cycle, SCL, has this periodicity. Since solar radiation supplies most of the energy that drives the dynamics of the terrestrial atmosphere, this long-term variation may modulate the time behavior of atmospheric parameters. In this work the behavior of long-time records of ionospheric, stratospheric and tropospheric parameters have been compared to that of SCL. These parameters are the maximum ionospheric electron density (measured around 300 km height) of four different ionospheric stations, the lower global sratospheric and the tropospheric temperature (air surface). There is a high correlation between each of them and SCL. The solar variability then, could be the responsible for the long-term variation observed in the atmospheric parameters here analyzed.
