Dear Colleagues,

This is a friendly reminder for the next 43rd COSPAR Scientific Assembly 
(COSPAR-20) that will take place in Sydney, Australia, on Aug. 15 – 22, 
2020. Please visit the web page at http://www.cospar2020.org/ for 
further details. The Call for Papers dead-line is approaching and we 
wouldn't miss your contributions.

Abstract submission deadline is 14 February 2020 at 23:59 (AEST) 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,

MSO David Altadill
DO Dieter Bilitza.
