(HILITES) Campaign
New
June 23, 1999
The HILITES Campaign
proposal authored by Thayer, Larsen, and Kane is now available, as
a pdf document, for comments and use by proposers. Please inform
thayer@sri.com of any suggestions you may have on the proposal content.
The HILITE campaign will study high-latitude electrodynamics through
coordinated observations by ground-based instrumentation and sounding rockets
near the town of Kangerlussuaq,
Greenland (formerly Søndre Strømfjord). Rockets are not
new to Kangerlussuaq as past NASA campaigns, such as the Cooperative Observations
of Polar Electrodynamics (COPE) program in 1985 and 1987, have used a rocket
facility just outside of town to carry out upper atmospheric studies .
These were successful campaigns, see list of
COPE publications, involving coordinated operations between the ground-based
instrumentation at the Sondrestrom incoherent scatter facility and the
rocket facility.
Discussions have begun concerning the possibility of carrying out
a new rocket campaign in Kangerlussuaq, Greenland to study the complex
processes at play in the high latitude E region. To kickoff the initiative
a two-hour workshop was held at the 1998 CEDAR meeting in Boulder Colorado
on June 10. A description of the workshop and a list of participates can
be found by following the link to the CEDAR
HLE Workshop.
The project continues to move forward. Since the CEDAR workshop
a series of meetings on science and logistics have been held. The results
of these meetings have been positive and informative. A chronology
of events summarizing these meetings , including the prepoposal meeting
at SRI in December 1998 and a US research in Greenland meeting at the Danish
Polar Center in Copenhagen on February 27, 1999, is given under the topical
heading of How is the project progressing?

Why Greenland?
-
The rocket dispersion zone is better than in most arctic rocket sites
with the possibilities of launching to the North, East, or South providing
polar cap or auroral zone measurements
-
The incoherent-scatter radar facility has improved in its capabilities
through improved radar pulse schemes, new instrumentation, and improved
infrastructure. These capabilities can better complement rocket measurements
-
The facility is located only about 13 km from the rocket range and is
readily available for supporting logistics and operations
-
The Kangerlussuaq International Science Support, KISS
facility, in town is fully supportive of scientific studies and can
provide the necessary accommodations for lodging, meetings, and storage
What is the Scientific Theme?
A central theme is important in establishing a focused campaign. The
most common theme from the workshop addressed understanding the height-resolved
electrodynamics at high latitudes involving measurements of neutral winds,
conductivities, ion and neutral composition and temperature, currents,
Joule heating rates ,etc... This theme relates directly to other initiatives
within NSF and NASA such as the NSF CEDAR program, the NASA
TIMED program, the planned NASA GED program, and the collaborative
TIMED/CEDAR
program , specifically the ion/neutral
coupling subgroup.Although the proposed central theme provides focus,
it does not exclude other possible experiments that may benefit by such
an arrangement of rocket payloads, ground-based instrumentation, and satellite
coverage nor the possiblity of revisions to the theme as discussions progress.
Feedback on this theme or other possible experiments would be appreciated
and can be conveyed through email to thayer@sri.com
