Simon Hook

Simon Hook is a geologist in the Earth Surface Science Group, Climate, Oceans and Solid Earth Science Section. His research is focused on improving our understanding of geologic and hydrodynamic processes on Earth and other planets. He is currently leading an international team of interdisciplinary scientists to relate recent observations of Mars to terrestrial environments and their relationship to water and life.

Simon is an expert on optical radiometry, in particular thermal infrared spectroscopy. He is a member of several instrument teams including AATSR, ASTER, MODIS, Landsat (5 and 7) and NPP. He has developed validation sites at Lake Tahoe, CA/NV and Salton Sea, CA for determining the absolute radiometry of airborne and spaceborne mid and thermal infrared radiometers and surface temperature retrieval algorithms. The measurements at the site are unique and now used as an absolute reference standard for multiple instruments developed by both domestic and foreign research agencies.

Simon continues to develop new instrumentation in support of scientific studies. He recently demonstrated a new design for a hyperspectral thermal imager in the laboratory using a QWIPS detector. He is now leading an effort to build an airborne hyperspectral thermal imager called HyTES in support on the NRC Recommended HyspIRI mission.

A key aspect of Simon's research is the development of new techniques to analyze and extract critical information from optical remotely sensed data, in particular, temperature and emissivity. Techniques developed by Simon are widely used by researchers and have also been incorporated into commercial packages.

Simon is actively involved in planning activities at NASA and other agencies for future missions. He is a co-lead on the NRC Recommended HyspIRI mission study (http://hyspiri.jpl.nasa.gov). He is also the chair of the JPL Science and Technology Advisory Committee which reports to the Chief Scientist and Technologist on how to improve research life at JPL.
