<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Manuscripts
are invited for a joint special section of JGR-Space Physics and
JGR-Atmospheres on trends in the middle and upper atmosphere and ionosphere.
Papers are welcome that apply all types of observational techniques to
determine the long-term changes and trends in the stratosphere, mesosphere,
thermosphere, and ionosphere, that have occurred in the past and also to
determine the processes behind those changes. Also solicited are contributions
which consider the availability, quality and acquisition of various data sets
which may be exploited for trend studies, and statistical methods for deriving
and validating those trends. Interpretation and attribution of observational
results depends heavily on theoretical models and numerical simulations of the
trends, and papers dealing with these topics are particularly welcome. While
the troposphere is not the main focus of the special section, it is clear that
it has a major role to play in middle and upper atmosphere trends; papers that
demonstrate this relevance are also appropriate.<o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Manuscripts
can be submitted either to JGR-Space Physics or JGR-Atmospheres, via the GEMS
website. If possible, please send tentative titles in advance to john.emmert at
nrl.navy.mil (this is not mandatory, but will help with planning). For more
information, please visit <a
