We invite research papers highlighting some of the new challenges and
promises that ground-based observations have to offer in the field of
solar-terrestrial research. Recently, new initiatives in ground-based
instrumentation have been taken up by several observatories around the world in the regime of optical, infrared and radio wavelengths. The spatial and temporal resolution of the ground-based observations
complement the space-based observations, in a unique way bridging the gaps and addressing important issues pertaining to forecasting of space weather events.

In this session, we also invite contributions on the new, proposed or
ongoing ground-based instruments, and the specific scientific goals that can be achieved through them. We also call for papers that emphasize the strength of ground-based network of instruments, for example, GONG, Callisto, GHN,etc. thereby improving the observing duty cycle and enhancing our understanding of the initiation and evolution of the solar activity.
