Lucien Froidevaux

Education
  • B.S.in Physics (magna cum laude), UCLA (1976)
  • M.S. in Earth and Planetary Sciences, Caltech (1981)
  • Ph.D. in Earth and Planetary Sciences, Caltech (1984)

Research Interests
  • Production of long-term stratospheric datasets from past data records.
  • Comparisons of long-term datasets to global chemistry climate models.
  • Earth's atmospheric composition and chemistry (e.g., ozone and chlorine issues).
  • Retrievals and validation of atmospheric composition from satellite measurements.

Projects

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.

GOZCARDS
Future generations will be in need of long-term data records of atmospheric composition to better understand the atmospheric variability and trends.
