SCOSTEP is tasked to organize organize long-term scientific programs in solar terrestrial physics. The program for 2020-2024 is Predictability of Variable Solar-Terrestrial Coupling (PRESTO). PRESTO was defined based on a community effort with numerous white papers submitted to the Committee for Definition of the Next Scientific Program (NSP) and two fora organized by the International Space Science Institute (ISSI) in Beijing in 2018 and in Bern in February 2019. PRESTO's goals are to "address the predictability of 1) space weather on timescales from seconds to days and months, including processes at the Sun, in the heliosphere and in the Earth’s magnetosphere, ionosphere and atmosphere, [and] 2) sub-seasonal to decadal and centennial variability of the Sun-Earth system, with a special focus on climate impacts and a link to the World Climate Research Program (WCRP) Grand Challenge Near-Term Climate Predictions as well as the IPCC." (NSP Concept Text).

PRESTO Logo Contest Winner Announced

We are pleased to share the results of the PRESTO logo contest. A total of 37 clever designs were submitted for consideration.  After much thought, the PRESTO committee selected the design provided by Mr. Vishal Jagatsing Pawar.  Mr. Pawar is a Master's Degree Candidate in Atmospheric and Space Science at Pune University in Maharashtra, India.

Congratulations to Mr. Vishal Pawar and thanks to all who submitted a design.


PRESTO is comprised of 3 Pillars:

Pillar 1. Sun, interplanetary space, and geospace
Pillar 2. Space weather and the Earth’s atmosphere
Pillar 3. Solar activity and its influence on the climate of the Earth System

Details are given in the ISSI-BJ Newsletter #13, also available at


In response to the current difficulties of hosting meetings in person, SCOSTEP-PRESTO is hosting online seminars to deliver the latest scientific topics and/or instructive review presentations on solar-terrestrial physics related to SCOSTEP's PRESTO program.

At this time, we are happy to announce the recordings of the first 4 seminars are now available at the links below.
