AB: On August 10, 2007 a dramatic polar mesospheric cloud display was observed visually and by a lidar system from the Sondrestrom Upper Atmosphere Research Facility near Kangerlussaq, Greenland (67.0N, 309.1E). The PMC was detected in the lidar's vertical beam from approximately 01:30 UT until local sunrise near 07:30 UT. The AIM spacecraft passed within a few hundred kilometers of the site near 02:20 UT, placing the site well within the viewing angle of the CIPS instrument. The SOFIE instrument on AIM made measurements within 700 km of the lidar observations. The lidar detection indicates typical PMC characteristics with an altitude near 82 km, a thickness of 1 km and a backscatter coefficient near 100. The CIPS images will place in context the lidar observations and the CIPS measurements of the scattering phase function will help constrain PMC particle size. The SOFIE measurements will help determine the temperature and water vapor conditions in the region of the lidar observations. The detailed lidar measurements complement the satellite observations and provide for the first time a detailed view of a PMC simultaneously from ground and space.
