*Invitation to 2015 CEDAR workshop "Long-term variations in the geospace
Long term variations in the geospace environment are caused by a variety
of sources, including the 11-year solar cycle and the secular variation
in the geomagnetic field. Accurate knowledge of long-term trends in all
portions of the geospace environment are essential to understand and
predict behaviour in the ionosphere and thermosphere. The changing
predictions for the current solar cycle (24) are a good example of how
this gap in our knowledge limits forecasting capability. It also
highlights the importance of incorporating multiple sources of data.
There are now many instruments and datasets that have been operating
continuously or sporadically over several solar cycles, allowing
long-term studies of the influence of solar irradiance, secular changes
in the magnetic field, and changes in the composition of the lower
atmosphere and thermosphere. This workshop will address the progress and
problems in our understanding of these long-term variations. Invited
talks will give an overview of the available datasets and discuss the
current state of investigation of long-term variations in the sun,
geomagnetic field, ionosphere/thermosphere, and lower atmosphere.
Submitted presentations and directed discussion will cover topics
including long-term variation in the solar spectrum, the influence of
changes in lower atmospheric composition on the upper atmosphere, and
the long-term variability of the ionosphere. This workshop will help
observational space physicists and modelers share their progress and
requirements to better attack the problem of long-term variations in
interconnected regions of the geospace environment.
*Time: 16:00-18:00 on June 25th, 2015 (Thursday)
We would like to inviteinterested people to present their work, tools,
or ideas in this session. More information can be found at the CEDAR
