Predictability of the Solar-Terrestrial Coupling


PRESTO is a science program that seeks to improve the predictability of energy flow in the integrated Sun-Earth system on times scales from a few hours to centuries through promoting international collaborative efforts. PRESTO is sponsored by SCOSTEP, the Scientific Committee on Solar Terrestrial Physics.

SCOSTEP is the only organization dealing with the coupled solar-terrestrial system under the umbrella of the International Science Council (ISC). PRESTO (2020 – 2024) is the latest program of SCOSTEP in the modern space era, following a number of programs such as CAWSES (2004-2008),  CAWSES-II (2009-2013) and VarSITI (2014-2018).

A new list of databases related to the Sun-Earth system is now available for community use. This database spreadsheet will be useful for interdisciplinary studies from the Sun to the Earth and for students and scientists in developing countries for their quick access to these resources on the web.

SCOSTEP/PRESTO will host an AGU Town Hall meeting on December 15th 2021 at 11:15-12:15 Central Standard Time. The Meeting number is TH33H.

SCOSTEP/PRESTO is accepting Grant Proposals for Campaigns and Meetings for 2022.
The deadline for proposals is December 31, 2021.
