Poker Flat 50th Anniversary
On March 9 we celebrated the 50th anniversary of the first rocket launches at Poker Flat (Tuesday 4 March 1969). Over 800 members of the public visited the range, and we provided lidar tours past midnight.  Local NBC affiliate Channel 11 visited the lidar lab and interviewed Jennifer Alspach. You can watch the story here.

Great Alaskan Railroad Journeys
Michael Portillo visited Poker Flat in summer of 2018 to see the rockets and lidars for an episode of this BBC show. The episode aired in the UK in February 2019 and is expected top air in the US late. Episode Details .

LCAGe: Results Presented
Jintai Li presented first LCAGe results relating gravity wave activity and instability at the Fall Meeting of the American Geophysical Union in December (Li et al. 2018).

MTeX: Results Published
The scientific results from the MTeX campaign have been published in November in the Journal of Geophysical Research (Triplett et al., 2018). The MTeX results show reduced turbulence associated with reduced gravity wave activity and suggest systematic reduction of turbulence in the wintertime Arctic middle atmosphere. The paper can be accessed on the PUBLICATIONS page.

LCAGe-1: Fall Campaign
As part of the LCAGe project we have just conducted an intensive observation campaign. With Biff Williams visiting from GATS, Jennifer Alpach, Jintai Li and Richard Collins made intensive lidar observations during an extended period of clear skies between September 27 and October 3 (September 28-October 3, UT). You can click on the first-look summary plot is posted below showing the sodium layer over the nearly 6 days. The data set featured two periods with full daytime and nighttime observations. The data is being analyzed to investigate waves and tides using the sodium and temperature and wind derived from the lidar measurements. Observations will continue through the winter.
