Bjorn Lambrigtsen
Group Supervisor

Bjorn Lambrigtsen is a scientist who specializes in microwave observations of the Earth's atmosphere. His research activities ranges from the development of new technology and observational systems to the study of hurricanes. Since 1991 he has been the Microwave Instrument Scientist for the Atmospheric Infrared Sounder carried on NASA's Aqua satellite. He is also a member of the science team for NASA's upcoming NPOESS Preparatory Project satellite mission - a pathfinder for the nation's next generation of weather satellites. He led the development of a new aircraft-based microwave sounder, HAMSR, which is used in NASA field campaigns to study hurricanes. Finally, he is leading the development of GeoSTAR, a new concept for a microwave sounder for geostationary satellites.

  • Ph.D.-level graduate work: Physics/J. Marburger, University of Southern California (1969-1978)
  • BS/MS-equivalent: Physics/I. Svare, Norwegian Institute of Technology (1967)

Research Interests
  • Microwave sounding: retrieval methods, new instruments/concepts
  • Hurricane research and data analysis
  • Science algorithm development


The Atmospheric Infrared Sounder, AIRS, is an instrument whose goal is to support climate research and improved weather forecasting.

The Geostationary Synthetic Thinned Aperture Radiometer (GeoSTAR) is a new concept for a microwave sounder, intended to be deployed on NOAA's next generation of geostationary weather satellites, the GOES-R series.

The National Polar-Orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) mission collects and distributes remotely-sensed land, ocean, and atmospheric data to the meteorological and global climate change communities.

The NASA African Monsoon Multidisciplinary Analyses (NAMMA) campaign is a field research investigation sponsored by the Science Mission Directorate of the National Aeronautics and Space Administration (NASA).

The Tropical Cloud Systems and Processes (TCSP) mission is an Earth science field research investigation sponsored by the Science Mission Directorate of the National Aeronautics and Space Administration (NASA).

The Genesis and Rapid Intensification Processes (GRIP) experiment was conducted to better understand storms and hurricanes.

HS3 Icon HS3
The Hurricane and Severe Storm Sentinel (HS3) is a five-year mission specifically targeted to investigate the processes that underlie hurricane formation and intensity change in the Atlantic Ocean Basin.
