style="FONT-SIZE: 14pt; mso-bidi-font-size: 11.0pt" lang=EN-US>We are suggesting
two MERINO campaigns in 2016. The first will be in spring spanning the period
from March 15 to April 15. A second campaign will take place likely during
Sep-Oct. These are follow-ups to successful prior campaigns conducted during
2014 and 2015. The March 2015 campaign enabled us catch the biggest-ever solar
storm for the current solar cycle. As before, our main goal is to examine how
difference the upper atmosphere/ionosphere behaviors during both the quiet and
storm period for the eastern and western hemispheres under opposite
geographic-magnetic coordinate offset. To reveal the underlying processes that
drive vertical coupling and horizontal variability, dedicated and coordinated
observations are essential. With increasing number of the observational data
available around the meridian circle of 120Eº/60Wº recently, the following
specific topics might be of particular interest: (I)</SPAN><SPAN

differences in the upper atmosphere/ionosphere over the US and East-Asia region
during the magnetic storm of different magnitude. (II) A system-wise perspective
of large scale traveling ionospheric disturbance (TID) and medium scale TID from
the high latitude to the equator. (III) Regional difference of the ionospheric
plasma irregularity/ scintillation. (IV) Interhemispheric difference of the
upper atmosphere/ionosphere along 120Eº/60Wº meridian. <o:p></o:p></SPAN></P>

style="FONT-SIZE: 14pt; mso-bidi-font-size: 11.0pt" lang=EN-US>The anticipated
ground-based upper atmospheric observational facilities consist of Chinese
Meridian Project observatories and other instruments in China, and US-NSF
geospace facilities (in particular, incoherent scatter radars) in American
sectors, optical and radio instruments facilities from Japan, Korea, Brazil,
India, Australia, Russia, and South-Asian countries. Our focus is the 120Eº/60Wº
meridian, however, observations from surrounding areas can put us on an
appropriate context, and therefore are strongly encouraged to participate as
well.<o:p></o:p></SPAN></P>
