Space Weather

Space weather refers to the conditions and phenomena in space caused by the Sun’s activity, including solar flares, coronal mass ejections, and variations in the solar wind. These events can affect the Earth’s magnetosphere, ionosphere, and thermosphere, impacting satellite operations, radio communications, navigation systems, and power grids. In geodesy, monitoring space weather is important because ionospheric disturbances can introduce errors in GNSS measurements and other space-based observations, requiring corrections for accurate positioning and Earth observation.
