Graeme Leslie StephensFRS[4] is director of the center forclimate sciences at theNASAJet Propulsion Laboratory at theCalifornia Institute of Technology[5] and professor of earth observation theUniversity of Reading.[6][7]

Education

[edit]

Stephens was educated at theUniversity of Melbourne in Australia where he received aBachelor of Science degree in Physics 1973 in followed by aPhD inmeteorology in 1977.[2]

Career and research

[edit]

Stephens research has provided leadership in three major disciplinary areas ofEarth sciences:

  1. Atmospheric radiation andradiative transfer[4]
  2. Earth observations andremote sensing[4]
  3. Understanding critical cloud-climate feedbacks and related effects on theEarth's energy budget[4]

Stephens has pioneered quantitative uses of global Earth observations and combined this with theory to study Earth'sclimate change feedback.[4] He provided leadership in designing and developing international satellite programs exemplified by his creation and leadership of the decade longCloudSat satellite mission[3] that is providing novel insights and understanding of the Earth's clouds, precipitation and their role in climate.[4][1][8]

Awards and honours

[edit]

Stephens was elected a member of theNational Academy of Engineering of theUnited States in 2015,[4] received theJule G. Charney Award of theAmerican Meteorological Society for pioneering advances in understanding and measuring radiation processes and their role in climate, and received the Gold Medal of theInternational Radiation Commission in recognition of world leading contributions to the radiation community.[4] He also receivedNational Aeronautics Space Administration, Exceptional Public Service Medal.[4] In 2025 he received theCarl-Gustaf Rossby Research Medal of the American Meteorological Society.[9]

He was elected aFellow of the Royal Society in 2018.[4]
