From Abigail M. Rymer (Abigail.Rymer at on 05 June 2012.

Dear Colleagues,

Please consider submitting a presentation to CEDAR 2012 workshop "In situ measurements of the mesosphere-lower thermosphere (MLT) by commercial suborbital spacecraft." Monday June 25th 16:00-18:00 PM.

The emergence of commercial spacecraft will provide frequent and low cost access to 60-120 km altitude; with multiple flights per day, gathering about 10 minutes of data per flight. Initially all the flights will be from the same location (probably New Mexico) and during the day. If, as seems likely, the use of sub-orbital vehicles for space-borne science investigations gains traction it is hoped that flights will launch from different locations and include night-time flights. These flights can be coordinated with observations done by ground-based radar measurements such as Arecibo and SuperDARN to help characterize the lower E- and D-region plasma environment of the ionosphere.

For this workshop we encourage participation from community members to explore what measurements (including coordinated observation campaigns) can be made to help us better understand this region in general. What in situ measurements should be made in order to characterize the region and to study specific peculiar phenomena observed in this region of the Earth’s atmosphere such as high altitude lightning, sprites, nocti-luminescent and polar-mesospheric clouds.

Please let us know if you would like to present at the workshop, both formal presentations and general suggestions for discussions topics are welcome, we hope to see you there!

Best regards, Abi Rymer
