CEDAR email: Call for papers for COSPAR 2020 Scientific event C4.1

[Vladimir Truhlik]

Dear Colleagues,

The next 43rd COSPAR Scientific Assembly (COSPAR-20) will take place in 
Sydney, Australia on Aug. 15 – 22, 2020. Please visit the web page at 
http://www.cospar2020.org/ for details.

The Call for Papers is open (abstract submission deadline is 14 February 
2020) and we would like to draw your attention to the scientific event
C4.1 Improving the Description of Hemispheric Differences in Ionospheric 
Models. The session is organized by the COSPAR/URSI IRI Working Group.
Hemispheric differences have been observed for many ionospheric 
parameters including, the seasonal variation of electron and ion
densities and temperatures. For example, the well-known Winter Anomaly 
exhibits a much stronger amplitude in the Northern hemisphere while the
semiannual anomaly is stronger in the Southern hemisphere, and the 
Northern hemisphere counterpart to the Weddell Sea anomaly in the
Southern Hemisphere is much weaker. We invite presentations that 
investigate how well models describe the structure of these hemispheric
differences with special emphasis on the IRI model, which is the ISO 
standard for the ionosphere. Because empirical models may have an
inherent bias due to differences in data coverage, it is important to 
verify that models like IRI correctly represent hemispheric asymmetries
well. Talks covering all aspects of the IRI modeling effort including 
model improvements, comparisons with new data, IRI extensions, and IRI
applications are encouraged. Presentations that investigate the causes 
of hemispheric asymmetries are particularly welcome.

We are looking forward to seeing you in Sydney,
