Profile
Summary: 

Michael Rennie is working on the European Space Agency's Aeolus Doppler Wind Lidar project. His current research topics include: developing the Aeolus Level-2B processor; preparing the operational Level-2B/C processing system and preparations for the data assimilation of Aeolus L2B line-of-sight winds, including monitoring tools for use in the mission's CAL/VAL and beyond.

Professional interests: 
  • Data assimilation with a focus on the use of wind and GPS radio occultation observations
  • Developing Satellite mission Ground Segment processing software and processing facilities
  • Developing monitoring software for meteorological observations
Career background: 

2011-present: Scientist at ECMWF working on the Aeolus Doppler Wind Lidar project

2005-2010: Scientist at UK Met Office working on the assimilation of GPS radio occultation

2001-2005: Studied for an MSci MA, Natural Sciences Tripos (physics), University of Cambridge
