*Invitation to "Global support of the CARINA Science Mission to study 
the Lower Thermosphere*"

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 

The workshop will be in two parts:
*Monday, June 22, 1330-1530 in Kane 110* to discuss the current mission
*Thursday, June 25, 1600-1800 in Kane 110* to discuss future 
high-laitude missions.

An overview of the CARINA mission will be presented at the Monday workshop.

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 
<paul.bernhardt at nrl.navy.mil> or Asti Bhatt (asti.bhatt at sri.com). The 
talks will be 5-10 minutes each.
