| Abstract: | When the solar irradiance propagates between the outer magnetospheric regions and the ionosphere, dynamic processes of the
magnetosphere-ionosphere-thermosphere system are affected at the lower end of their paths by the interaction of radiation
with the neutral troposphere. The main target of this work is to investigate the relationship between the diurnal magnetic
field variations resulting from solar activities and the variation in the troposphere temperature. Meteorological and geomagnetic
data acquired from different observatories located in Egypt, Portugal and Slovakia in a long-term and daily-term scales were
analyzed. |
