All-sky interferometric meteor radar meteoroid speed estimation using the Fresnel transform Annales Geophysicae, 2007 (Ref: 12856)
Category 1: Peer-reviewed literature

Fresnel transform meteor speed estimation is … investigated. A spectral based technique is developed allowing the transform to be applied at low temporal sampling rates. Simulations are used to compare meteoroid … speeds determined using the Fresnel transform and alternative techniques…

The first bipolar seasonal investigation of the PMSE layer near the latitude 69° as a function of mesosphere temperature and wind state. Proceedings of MST11: Eleventh International Workshop on Technical & Scientific Aspects of MST radar, Gadanki/Tirupati, India, 11-15 December 2006, 2006 (Ref: 12782)
Category 3: Abstract

The existence of Polar Mesosphere Summer Echoes (PMSE) in the Southern … Hemisphere (SH) has been confirmed using MST radar, HF radar and a Dynasonde. Studies spanned the geographic latitudes 62.1°S (Machu Picchu), 68.6°S (Davis), 69.0°S (Syowa), and 75.5°S (Halley Bay).

Observations of Polar Mesosphere Summer Echoes with absolute calibrated MST radars in the Northern and Southern hemisphere: Interhemispheric similarities and dissimilarities. MST11: Proceedings of the Eleventh International Workshop on Technical & Scientific Aspects of MST radar, Gadanki/Tirupati, India, 11-15 December 2006, 2006 (Ref: 12781)
Category 3: Abstract

Mesosphere Summer Echoes (MSE) have been observed with 50-MHz VHF … radars at middle (MSE) and polar latitudes (PMSE) in the Northern Hemisphere for … more than 20 years. However measurements in the Southern Hemisphere were in the … past rare and limited to low southern latitudes.
