Our scientific opportunities support the community through six distinct modes of operation. Links to proposal templates or on-line submission forms are provided for each individual tool.

Find explanations, forms of applications and an overview of current and past activities.

Workshops are selected by the ISSI directorate in consultation with the Science Committee. The Workshop programme and speakers are selected by a group of highly qualified experts acting as convenors. Each Workshop lasts a week and has up to 45 participants. Workshop participants work together to produce an on-line collection of peer-reviewed articles in Space Science Reviews or Surveys in Geophysics. This collection of review papers is then also published as a volume of the Space Science Series of ISSI (SSSI). All Workshop publications have Open Access status.

The Chronology of the Very Early Universe According to JWST: The First Billion Years

This is the first in the new series of Breakthrough Workshops that we are starting at ISSI. Breakthrough Workshops are designed to address one key question in science, by gathering the main experts on the topic, invite them to spend a week in a neutral and welcoming environment, discuss the issues, and produce one high...

Magnetic Switchbacks in the Young Solar Wind

The Workshop aims at providing a more comprehensive understanding of the nature and elusive origin of magnetic switchbacks as observed in the inner heliosphere, and their role in structuring the solar corona. Switchbacks have received considerable attention since the Parker Solar Probe Mission has found them to be ubiq...

Evolution of the Solar System: Constraints from Meteorites

The Workshop presents research on primitive meteorites and how results fit into theoretical models of the early solar system. The impact of recent progress in analytics, and of samples returned from asteroidal bodies advances the understanding of the formation of meteorites and their components and ultimately the forma...

Tipping Points and Understanding EO data needs for a Tipping Element Model Intercomparison Project

With relevance for priorities also of the World Climate Research Program (WCRP), the aim of this Workshop is to advance knowledge about tipping elements and irreversibility, and impacts on Earth‘s climate and environment. As such the Workshop would strive to address a consistent approach in the handling of data relat...

Challenges in the Understanding of the Global Water Energy Cycle and its Changes in Response to Greenhouse Gases Emissions

Radiative processes are key to the climate’s water-energy cycle: Climate is determined by the imbalances of solar radiative heating and long-wave radiative cooling. The circulation of the atmosphere and ocean, the environment on land, and the biosphere are all driven by local radiative imbalances....
