I had our student space mission design class work on a very similar problem a few years back. I will see if I can pull together some of that study. I worked on it with Sid Henderson one of my past students.

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 coefficients.

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