Curriculum Vitae:

Glynn Hulley

Dr. Glynn Hulley is a member of the Carbon Cycle and Ecosystems group at the Jet Propulsion Laboratory. His research is focused on improving our understanding of Earth surface properties, ecosystem and hydrological processes. Glynn is an expert on thermal infrared spectroscopy, and is a member of several instrument and product development teams including ECOSTRESS, ASTER, MODIS, VIIRS, and Landsat. A key aspect of Glynn's research is the development of new techniques to analyze and extract land surface temperature and emissivity (LST&E) from thermal remotely sensed data. Techniques and algorithms developed by Glynn have been incorporated into commercial packages by NASA and are widely used by researchers, for example the ASTER GEDv3, NASA MOD21 and VNP21 LST&E and MEaSUREs LST&E products. Using these LS&E products he is currently leading a study to investigate warming trends and heat wave characteristics in large urban centers in the USA.

He is currently the Level-2 thermal infrared lead for the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS), which will offer clues about how Earth's water and carbon cycles affect plant growth and how ecosystems adapt to changes in climate by measuring the loss of water from leaves and soil over the diurnal cycle. He has also worked extensively with a new airborne Hyperspectral Thermal Emission Spectrometer (HyTES) developed at JPL in an effort to develop algorithms and science objectives for the thermal infrared sensor on the HyspIRI Satellite Mission recommended by the National Research Council (NRC) Decadal Survey for Earth Science.
