CEDAR email: AOGS 2015 session ST24 "Solar activity , Space Weather and Space Climate in SCOSTEP’s VarSI TI program"

[Katya]

Dear colleagues,

We invite you to submit abstracts to the ST24 session "Solar activity,
Space Weather and Space Climate in SCOSTEP’s VarSITI program" at AOGS
2015, to be held in Singapore from 2 to 7 August.

Below is the description of the session. The abstract submission deadline
is 18 February 2018.

We hope to see you in Singapore.

Best regards,

Katya Georgieva and Kazuo Shiokawa, conveners

ST24. Solar activity, Space Weather and Space Climate in SCOSTEP’s VarSITI
program

The Sun, its extended corona, the interplanetary space, the Earth’s
magnetosphere, ionosphere, middle and low atmosphere, are all parts of a
complex system – the heliosphere. Various manifestations of solar activity
cause disturbances known as space weather effects in the interplanetary
space, near-Earth environment, and all the Earth's ”spheres”. Long-term
variations in the frequency, intensity and relative importance of the
manifestations of solar activity are due to the slow changes in the output
of the solar dynamo, and they define space climate. Space climate governs
long-term variations in geomagnetic activity and is the primary natural
driver of terrestrial climate. To understand how the variable solar
activity affects the Earth’s environment, geomagnetic activity and the
atmospheric system on both short and long time scales, we need to
understand the origins of solar activity itself and its different
manifestations, as well as the sequence of coupling processes linking
various parts of the system. This is the goal of the new 5-year program
VarSITI (“Variability of the Sun and Its Terrestrial Impacts”) of the
Scientific Committee on Solar-Terrestrial Physics (SCOSTEP) which started
in 2014. This session provides a forum to discuss the chain of processes
and relations from the Sun to the Earth’s surface: the origin and
long-term and short-term evolution of solar activity, variations in solar
total and spectral irradiance and their effects on the Earth’s system,
initiation and temporal variations in solar flares, CMEs, coronal holes,
the solar wind and its interaction with the terrestrial magnetosphere, the
ionosphere and its connection to the neutral dominated regions below and
the plasma dominated regions above, the stratosphere, its variations due
to the changing solar activity and its interactions with the underlying
troposphere, and the mechanisms of solar influences on the lower
atmosphere on different time-scales. Particularly welcome are
interdisciplinary papers highlighting the coupling processes between the
different domains in this complex system.
