    Dr. William B. Cook has over 30 years of research experience in high resolution interferometry, remote sensing, and optical instrumentation design and operation.  Most of his work at NASA Goddard has centered on project support of the ICESat2/ATLAS mission, and he is currently the lead scientist on the MABEL airborne test bed for that mission.   He has been a principal investigator and co-investigator on numerous NASA and industry-sponsored projects including the conceptualization and development of novel Fabry-Perot and Michelson-type interferometers, gas filter radiometers, and lidar systems.  While at NASA Langley, Dr. Cook’s focus was to ascertain or define measurement requirements for the NRC Decadal Study missions ASCENDS, GEO-CAPE and GACM and develop sensor concepts that met those requirements. In addition to a CO/CH4 sensor development and IR instrument modeling program, Dr. Cook led the hardware development of a dual infrared etalon Fabry-Perot spectrometer for measuring ozone profiles in the lower and mid-atmosphere from a space-based platform. Dr. Cook has served on various NASA instrument review panels, including acting as group lead for several review panels for NASA's Planetary Instrument Definition and Development Program.

    Before coming to NASA, Dr. Cook held research and teaching positions at the U. of Michigan and was a senior physics engineer at Raytheon E-Systems. At the U. of Michigan’s Space Physics Research Laboratory he was a member of the UARS/HRDI team and the TIMED/TIDI team, and was PI for many low-TRL infrared and visible remote sensing instrument development projects. Two of these projects led to his involvement (as Co-I and instrument lead) on two very highly rated NASA proposals: ESSP/STROBE (D. Anderson/JHUAPL, PI) and UNESSP/FLEXSAT (B. Rock/UNH, PI). Early in his career Dr. Cook developed expertise in detector physics and far-infrared characterization techniques for semi-conducting and superconducting materials, and was a consultant for Hughes (eventually Raytheon) SBRC characterizing some of the first thin-film MCT devices and quantum well structures. Dr. Cook's graduate work at Florida State University consisted of the design and construction of a very high resolution Fourier Transform Spectrometer and its use in the study of torsion-rotation bands in hydrogen peroxide and methanol.

    Research Interests

    Remote Sensing Instrumentation

    Primary interest is in the development of novel remote sensing instruments including interferometers (FTS and Fabry-Perot), radiometers (e.g. gas filter correlation) and lidars.      Science applications are predominately Earth science/atmospheres/vegetation/ice  but with some applications to planetary studied in general (e.g. Martian atmosphere).
     

    Vegetation Fluorescence

    Developing a means to measure terrestrial chlorophyll fluorescence emissions to be used to better characterize Global Primary Productivity and eventually better characterize the role of land/vegetation to the carbon cycle.  Currently Co-I on VegFusion aircraft mission proposal submitted to EV-S, PI on IRAD project developing the measurement concept, also Deputy PI on a developing mission for upcoming Earth Venture opportunities.

    MABEL observations of ice and snow

    Currently lead/PI for flights of MABEL instrument in support of ICESat2 algorithm development.   Ultimately plan to participate in validation and other science work when ICESat2/ATLAS is launched.

    Measurement of Atmospheric Trace Species

    Developing/devising new instruments and continuing development of existing instruments to study atmospheric constituents on Earth and Mars (e.g. CO, CO2, CH4, nitrogen compounds and O3).

    Current Projects

    ICESat2/ATLAS/MABEL


    Started in August 2010 on ICESat2/ATLAS  as lead for the instrument's Fabry-Perot filter design then almost immediately became Deputy Instrument Scientist, and then Instrument Scientist.   Higher level oversight was deemed necessary and so became Deputy Project Scientist- Instrument in 2011.
    In early 2013 changed positions to become lead scientist/PI on the MABEL airborne testbed lidar  for ICESat2.   Presently leading MABEL maintenance and hardware upgrades and its operation aboard ER-2 and Proteus high altitude aircraft.

    Remote Sensing Chlorophyll Fluorescence (GSFC IRAD and B&P)

    Leading risk reduction activities and demonstration of new measurement techniques, and providing real data to colleagues performing modeling and simulation of remotely sensed fluorescence signatures.
