Pre-Meeting Workshop

Monday, August 30 | 7:30 am - 10:30 am MDT

Workshop Option 1

Radiometry Revealed

Dr. Joseph Shaw, Director of the Optical Technology Center and Distinguished Professor of Electrical Engineering and Optics, Montana State University

This course explains basic principles and applications of radiometry and photometry. A primary goal of the course is to reveal the logic, systematic order, and methodology behind what sometimes appears to be a confusing field. Examples are taken from the ultraviolet through the long-wave infrared portions of the electromagnetic spectrum. The tutorial is designed for those who are new to radiometric measurements and calculations and should help if you have questions such as, "how many watts or photons do I have in this measurement?" or "how much optical energy or radiation do I need?"

Joseph Shaw is the Director of the Optical Technology Center and Distinguished Professor of Electrical Engineering and optics at Montana State University in Bozeman, Montana. His research involves designing optical remote sensing instruments and techniques for solving practical problems in fields ranging from climate science to ecology. He earned a Ph.D. and M.S. in Optical Sciences at the University of Arizona, M.S. in Electrical Engineering at the University of Utah, and B.S. in Electrical Engineering at the University of Alaska Fairbanks. Dr. Shaw is a fellow of SPIE and OSA.

Workshop Option 2

Current Challenges in the Remote Sounding of the Earth

Dr. Christopher (Chris) Barnet, Senior Scientist, Science and Technology Corporation (STC) and NASA Sounder Discipline Lead (2014-present)

This workshop will focus on the topic of remote sounding of the Earth’s atmosphere using modern space-borne hyperspectral infrared (e.g., AIRS, IASI, CrIS) and microwave (e.g., AMSU, MHS, ATMS) instruments to extract information about the Earth’s atmosphere. This workshop will have three major sections. The first section will be a conceptual introduction to the mathematical methods of sounding, that is, radiative transfer and inversion (a.k.a. retrieval) of observations. The second section will highlight the NOAA-Unique Combined Atmospheric Processing System (NUCAPS) and the Community Long-term Infrared Microwave Coupled Atmospheric Product System (CLIMCAPS) to illustrate the value and limitations of modern operational products and our ability to validate and utilize them. The third section will focus on the lessons-learned over the last decade and some thoughts on a path forward for new sounding instruments and capabilities. The over-arching goal of this workshop is to stimulate discussion on how we, as a community, can improve the use of sounding for greater societal benefit. Each section will consist of a ~30-minute presentation followed by ~30 minutes of discussion.

Chris Barnet, Science and Technology Corporation

Dr. Barnet’s career began as a welder at Fermilab - an accelerator laboratory for high energy physics. That fortuitous experience led to a “random walk” of working with superconductors, radio telescopes, array processors, Space Shuttle testing, planetary imaging and sounding missions, and finally Earth remote sounding. Along the way he earned a B.S. degree in electronics technology (1976), an M.S. degree in solid-state physics (1978), and a PhD in planetary astronomy (1990). His training as an engineer and physicist provided a foundation for understanding modern infrared and microwave instruments while his astronomical perspective enabled him to find some interesting ways to transition new algorithm concepts into these operational applications. For the last 25 years Dr. Barnet has worked to create a suite of operational Earth sounding algorithms culminating in the NOAA-Unique Combined Atmospheric Processing System (NUCAPS) for weather and air-quality applications and the Community Long-term Infrared-Microwave Coupled Atmospheric Product System (CLIMCAPS) for atmospheric climate and chemistry research applications.
