PRESTO (PREdictability of the variable Solar-Terrestrial cOupling) (https://scostep.org/presto/) is a 5-year science program (2020-2024) that seeks to improve the predictability of energy flow in the integrated Sun-Earth system on times scales from a few hours to centuries by promoting international collaborative efforts. PRESTO is sponsored by SCOSTEP, the Scientific Committee on Solar Terrestrial Physics. The mission of PRESTO is to identify predictability of the variable solar-terrestrial coupling and its performance metrics through modeling, measurements, and data analysis, and to strengthen the communication between scientists and users. PRESTO is aligned along three Pillars of research, i.e., Pillar 1: Sun, interplanetary space and geospace, Pillar 2: Space weather and the Earth’s atmosphere, and Pillar 3: Solar activity and its influence on the climate of the Earth System. These three Pillars were carried out in collaboration with relevant satellite and ground-based missions as well as modeling efforts to facilitate the implementation of these projects. The papers in this special issue will review scientific achievements obtained from the 5-year PRESTO activities and address possible future directions of these fields.
