<b>Invitation to "Global support of the CARINA Science Mission to
study the Lower Thermosphere</b>"<br>
<br>
The Naval Research Laboratory is constructing two satellites to fly
below the F-Layer ionosphere for a period of 45 to 60 days. The
Space Plasma Mission will study (1) high power RF wave interactions
in the Ionosphere, (2) sporadic-E layer characterization, and (3)
global imaging of F-Layer ionosphere. The CARINA spacecraft will be
launched in mid 2016 into a 51.6° inclination orbit that has in
initial insertion of 178 km by 284 km. The purpose of the CEDAR
Workshop on CARINA is to build ground support and theory teams for
the two-month mission. The six areas of research are (a)
Sporadic-E/Intermediate Layers and TIDs with a focus on ionospheric
structures below orbit and large scale bottomside fluctuations in
the F-Layer, (b) global assimilation for using the CARINA OGR and
RLP observations as drivers for data driven ionospheric models such
as GAIM, IDA3D, etc., (c) HF propagation and radio scintillations to
determine the impact of the bottomside ionosphere on HF ray
trajectories for SuperDARN, ionosondes, etc., and to determine the
effects of ionospheric irregularities and UHF/L-Band scintillation
on GPS, etc., (d) lightning and ocean waves to directly measure
lightning EM pulses and determine their impact on the ionosphere as
well as derive ocean wave height spectrum from HF surface wave
scatter, (e) high power HF modification from the Arecibo and SURA
Heating Facilities with direct sensing of artificial irregularities
and enhanced ionization, and (f) satellite drag with
thermosphere/mesospheric density updates determined by orbit
measurements and reentry modeling of drag coefficients.
<br>
<br>
The workshop will be in two parts: <br>
<b>Monday, June 22, 1330-1530 in Kane 110</b> to discuss the current
mission <br>
<b>Thursday, June 25, 1600-1800 in Kane 110</b> to discuss future
high-laitude missions. <br>
<br>
An overview of the CARINA mission will be presented at the Monday
workshop.
<br>
<br>
We invite you to present on any of the topics listed above and
participate in the discussion on how the CEDAR community can benefit
from the CARINA mission. Please email Paul Bernhardt
