Lidar Studies of Coupling in the Arctic Atmosphere and Geospace (LCAGe)
The LCAGe project focuses on understanding the coupling between terrestrial weather and space weather based on lidar observations of the Arctic mesosphere and lower thermosphere. A new sodium resonance wind-temperature lidar (SRWTL) was installed at LRL-PFRR in November 2017. The SRWTL will provide high resolution measurements of the meteorology that will be combined with other measurements made by complementary lidars, radars, and imagers at PFRR. The project involves researchers from UAF and GATS, and students from UAF.
This investigation is supported by NSF.

Transport, Chemistry, and Energetics of Water in the Mesosphere and Lower Thermosphere (SuperSoaker)
The SuperSoaker experiment was designed to investigate the impact of a water release on the atmospheric environment. The experiment combined a water release with ground-based lidar measurements that measured the cloud formed by the water release. The experiment was conducted in January 2018 at PFRR. The experiment involved researchers from six institutions (ASTRA, Clemson, GATS, NRL, UAF, and USU), staff from UAF and NASA, and students from UAF and USU.
This investigation was supported by NASA.

Mesosphere Lower Thermosphere Turbulence Experiment (MTeX)
The MTeX experiment investigated the relationships between turbulence, waves, and instabilities in the Arctic stratosphere-mesosphere-thermosphere. The experiment combined rocket-based ion-gauge measurements of turbulence with ground-based lidar measurements of waves and instabilities. The experiment was conducted in January 2015 at PFRR. The experiment involved researchers from seven institutions, staff from UAF and NASA, and students from UAF, Clemson, and Embry-Riddle. The MTeX measurements found low levels of turbulence that coincided with low levels of wave activity, and suggest that turbulence activity may be systematically low in the Arctic associated with systematically low levels of wave activity in the Arctic.
This investigation was supported by NASA.

Wave Driven Circulation and Variability of the Arctic Atmosphere (ArcWAVE)
The ArcWAVE project focused on understanding the wave-driven circulation and variability of the Arctic atmosphere. his study drew on lidar, reanalysis and satellite observations to understand the interactions between gravity waves, planetary waves, and the mean flow. The study found systematic interannual variability in gravity wave activity, with primary control of the wave activity by the mean flow. Secondary control was found due to unbalanced flow. The project involved researchers from UAF and CU, and students from UAF.
This investigation was supported by NSF.
