Carbon Cycle And Ecosystems

Biography

Dr. Glynn Hulley is a member of the Carbon Cycle and Ecosystems group at the Jet Propulsion Laboratory. His research interests include the remote sensing and retrieval of Earth surface land surface temperature and emissivity, urban climate science, heat waves and public health impacts, and ecosystem and hydrological processes. Glynn is an expert on multi- and hyperspectral thermal infrared spectroscopy, and is a member of several instrument and product development teams including ASTER, ECOSTRESS, MODIS, Suomi-NPP, 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. He is principle investigator for the development and validation of standard NASA Land Surface Temperature (LST) and emissivity products for MODIS, VIIRS, and Landsat, and is the level-2 thermal lead for the ECOSTRESS mission. He has extensive experience with aerial data acquired by the Hyperspectral Thermal Emission Spectrometer (HyTES) developed at JPL in 2013, and is currently on the thermal infrared phase-A study team for NASA’s Surface Biology Geology (SBG) Earth System Observatory mission to launch in 2028.
