user requirements in particular in safety of life (SoL) and precise
positioning applications shall be continued in a more concretized form
than we could do at the 42nd COSPAR assembly. Initiated studies shall
be reviewed and conclusions shall be drawn which indices are considered
as potentially applicable for selected use cases. In order to judge the
suitability, specification of user needs for various applications are
required from customers. Therefore, intensification of the dialog
between ionospheric scientists and customers is encouraged. Best
practice experience obtained in weather/ionospheric weather services
should be presented. Being aware that forecasts of the expected behavior
of indices used by customers require intensive scientific research in
the context of overall space weather processes, related scientific work
should be discussed to enable or further improve forecasting of
ionospheric indices. Therefore, contributions from SW experts covering
all other fields of space weather are encouraged. Progress on the
development of an Ionospheric Scale related to the indices is also
encouraged.</div><div><br></div><div>Following the two half-day formal
sessions a short 2 hour side meeting will discuss the future steps
required to develop an Ionospheric Scale, targeting ionospheric impacts
on Space Weather operations, similar to NOAA R, S, and G Scales
currently used internationally.</div><div><br></div><div>Sincerely,</div><div>Session Conveners: Norbert Jakowski and Tim Fuller-Rowell<br></div><div><a href="mailto:Norbert.Jakowski@dlr.de" target="_blank">Norbert.Jakowski@dlr.de</a></div><div><a href="mailto:Tim.Fuller-Rowell@noaa.gov" target="_blank">Tim.Fuller-Rowell@noaa.gov</a></div><div class="gmail-adL">______________________________________________________________<br></div></div><div><br></div><div><br></div></div>
