Dr. Manson’s research interests lie in the area of the Earth’s middle atmosphere and thermosphere (20-150 km): dynamics, chemistry, aeronomy and coupling processes. There are 3 main thrusts:
Remote Sensing of the Atmosphere using Radars Dr. Manson and his colleague, Dr. Chris Meek (Research Associate), have been contributing for over 30 years to the development and operation of radars (Medium Frequency, MF, 2-3 MHz) for the sensing of winds, waves [atmospheric gravity, planetary and tidal] and electron densities in the middle atmosphere (50-110 km). They use advanced technologies, and sophisticated analysis methods, for the real-time production of winds profiles (3 km, 5 min sampling). These advances are applied to the main MF radar near Saskatoon 52N…also to other smaller MF radars. Since 1987 one is at Ramfjordmoen (70N, Norway) beside the EISCAT facility and its Meteor Radar, also near ~100km the radars and lidars of ALOMAR/Andenes. Drs Manson and Meek are also the “mentors” [principle investigators] of the Arctic Meteor Wind/Temperature Radar at Eureka (80N, Canada).
Dynamics of the Middle Atmosphere/ Thermosphere The “Atmospheric Dynamics Group” has now archived almost three solar cycles of winds data. These data are analyzed by advanced spectral techniques to allow process-studies and to obtain climatologies of tidal, planetary and gravity waves. They have spatial scales of 10-10,000 km, and periods of minutes to many days. They interact with the atmosphere and each other in complex, non-linear fashions. Such waves have sources in the lower atmosphere or troposphere, associated with the ozone layer, water vapour, the Arctic Polar Vortex, jet-stream and thunderstorms. Together they redistribute energy, momentum and gaseous-minor constituents and pollutants throughout the entire 100 km-thick atmosphere of the planet. Radar and satellite data (Odin-OSIRIS, Aura-MLS, SCISAT-ACE and TIMED) are archived and used to study regional and global Atmospheric Processes Of Climate and its Change (APOCC).
Canadian Network for the Detection of Atmospheric Change (CANDAC), Global Programs Dr Manson is a Co-Investigator within the CANDAC Polar Environment Atmospheric Laboratory (PEARL) located on Ellesmere Island and “mentor” of its Meteor Radar (80N). Our theme in PAHA is the disturbed Polar Vortex and their effects upon our weather and climate. He continues activity within SCOSTEP and its VarSITI 2014-18: Variability of the Sun and Terrestrial Impact. Global arrays of radars (MF/meteor), opticals, satellite systems and Global Models GCM with Assimilation are used.
