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 (2019 – 2023) is the latest program of
SCOSTEP in the modern space era, following a numberof programs such as CAWSES (2004-2008), CAWSESII (2009-2013) and VarSITI (2014-2018).

he Sun is a variable star and its variability influences the Earth’s space environment. Furthermore,changing solar magnetic fields, radiative and energetic
particle fluxes force the Earth’s atmosphere and climate.
Transient energetic events such as flares, coronal massejections (CMEs), interplanetary shocks, stream interaction regions (SIRs), corotating interaction regions(CIRs) and energetic particles adversely impact criticaltechnologies based in space and on Earth that our society is increasingly dependent upon. At the same time, themiddle and upper atmosphere/ionosphere are impacted
by processes originating at lower altitudes, e.g., by atmospheric gravity waves, tides and planetary waves and

SCOSTEP/PRESTO NewsletterVol. 22changes in radiatively active gases. Solar influence on
climate is gaining increasing attention since variations
in solar activity do not only impact middle atmospherechemistry and physics, but have been shown to impact
decadal variability at the Earth surface. This is in particular interesting and important for decadal climate predictions. With the enhanced understanding of causal
connections in the Sun- Earth system maturing over thelast several decades, fueled by both observations andtheoretical modelling, we are in the position to transform this understanding to improved predictions of the
Sun-Earth coupled system, which is of relevance to thesociety and the focus of the current PRESTO program.

RESTO 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

Background

Plan of action

eliospheric transients originating from the Sun,
stream interaction regions (SIRs), fast streams,
coronal mass ejections , as well as Solar Energetic Particles (SEPs) are key agents driving disturbances in geospace. Their formation and evolution, solar wind magnetospheric coupling and ensuing magnetospheric
dynamics form a complex chain. Predicting accurately
and reliably various geospace disturbances, includingchanges in near-Earth plasma waves and radiation environment, requires understanding the key aspects of related phenomena, physical processes and their interplay
from Sun to Earth operating over timescales ranging
from milliseconds to days. Despite significant advancements in the field, long-lead time predictions require
still major improvements. There are for example often
significant uncertainties, related to CME parameters
and boundary conditions that are fed into the advanced
numerical simulations, empirical and semi-empirical
forecasting models. Improved physical understanding of
their nature and geometry and complex interaction
properties will also improve predictions.

The plan of key actions includes

Meeting Report

he thermosphere and the ionosphere are conventionally known to be directly affected by the varying magnitudes of solar activity. When incidence of
solar flux or energetic charged particles increases suddenly due to the occurrence of solar flares or coronalmass ejections combined with magnetic reconnection in
the Earth’s magnetosphere, the adverse effects witnessed in the ionosphere-thermosphere (IT) system as awhole are referred to as Space Weather effects. Consequently, these space weather effects lead to adverse effects in several space and ground-based applications as
illustrated in Figure 1. These effects and consequences
are to be understood at both fundamental and applications levels.

ore recently, it has been recognized that waves
originating in the lower atmosphere are an additional important source of IT variability. These waves
encompass a vast range of temporal (minutes to weeks)
and spatial (few kms to global) scales, and introduce asimilarly large range of spatial and temporal variability
in the IT. Changes in the IT due to wave-driven processes can reach magnitudes similar to moderate geomagnetic storms, illustrating their importance in modifying
the IT system. Furthermore, wave-driven processes introduce variability in the entirety of Earth’s atmosphere,
as shown in Figure 2, which illustrates the numerous
aspects of atmospheric variability that occurs in large
scale phenomenon such as in sudden stratosphericwarming events.

ecent improvements in observational and modelingcapabilities make addressing these questions timely. Current global observational infrastructure provides
an unprecedented view of the IT system from both
ground and space based instrumentation. Combinedwith recent modeling developments, such as whole atmospheric models that extend from the surface to theupper thermosphere, it will be possible to make significant progress in addressing Q2.1-2.4 in the coming
years. We invite and encourage active participationfrom the global community in advancing understandingof any of the questions mentioned above.

Upcoming Meetingsn order to enhance the predictive capability of the IT
spatial and temporal variability, it is necessary tounderstand how the IT system is affected by both coupling from above and below. Several features that areformed and/or affected due to these effects are plasma
irregularities, plasma bubbles, ion-drifts, ionosphericcurrents, thermospheric densities and composition, neutral winds and waves, etc. These features adversely affect trans-ionospheric radio communication, high frequency terrestrial radio propagation, thermal and dragenvironments for spacecraft in the increasingly congested Low Earth Orbit (LEO, < 2000 km) region. In orderto improve the understanding and predictability of the
middle and upper atmosphere, Pillar-II of PRESTO
aims to address the following main scientific questions:Meeting Report

Q2.1 How does the ther mospher e and ionospher e
respond to various forcings from above and from below?
Q2.2 How do atmospher ic waves and compositionchanges impact the middle and upper atmosphere?
Q2.3 What is the magnitude and spectr al char acter istics of solar and magnetospheric forcing, needed for
accurate predictions of the atmospheric response?

BackgroundT

Meeting Reporthe next 5 years spanning the start of Solar Cycle 25
through its (near) peak provide an excellent opportunity for evaluating our understanding and ability to
predict solar activity on decadal time scales. Predictability requires improved understanding of the physicalpathways wherein solar variability impacts the atmosphere, from the magnetosphere through the troposphere.
The nonlinear and stochastic mechanisms which modulate the solar cycle and affect the scope of the prediction
and predictability of the solar cycle are still open questions. In some areas, decadal-scale solar forcing remains
to be quantified to climate-relevant accuracies, whichchallenge our ability to determine causal connections in

the pathways explaining solar forcing impacts on climate. Furthermore, due to wave-driven coupling in theatmosphere, improving predictability of solar forcing
also requires improved characterization of the atmosphere-ocean response to the forcing.

The activities of this PRESTO pillar are organizedaround these science questions:1.

How will future solar activity vary over different
timescales and what are the physical reasons forthe variations?

2.

How will the solar forcing on the Earth’s systemevolve in the future?

random noises in the poloidal field generation bring the uncertainty of the poloidal field generation at cycle
minimum, which determines the subsequent cycle strength. The uncertainty accumulates with time. Thissignificantly limits the scope of the cycle prediction. (Credit: Jie Jiang)

level with their uncertainties and probability estimates.
Similar scenarios for the spectral solar irradiance andenergetic particle precipitation will be built from the
projected level of solar activity. The studies of the
Earth’s responses to the solar forcing will provide information about its importance for the predictability of theclimate on different time scales.

the framework of three working groups (WGs).
The WG activity will be concentrated on solar cycle
variability and predictability (WG1); solar forcing(irradiance and energetic particles) variability and predictability (WG2); and solar activity influence on climate and prediction on different timescales (WG3).
