Alyn Lambert

  • B.Sc. Physics with Astrophysics (Honors, First Class) University of Leeds, UK (1982)
  • Ph.D. Physics, University of Leeds, UK (1986)

Research Interests
  • Theory and practice of remote sounding of the Earth's atmosphere from satellite platforms.
  • Development of operational algorithms for forward modeling of atmospheric radiances and inverse modeling for retrieval of geophysical data products.
  • Innovative analyses combining Aura MLS measurements of gas-phase HNO3 with CALIPSO CALIOP lidar measurements to study early winter formation and development of PSCs and denitrification through sedimentation of PSC particles.


MLS - Microwave Limb Sounder Icon MLS - Microwave Limb Sounder
The Microwave Limb Sounder (MLS) experiments measure naturally-occurring microwave thermal emission from the limb (edge) of Earth's atmosphere to remotely sense vertical profiles of atmospheric gases, temperature, pressure, and cloud ice.
