    Dr. David Harding conducts research in the topographic expression of land surface processes and the physical properties of vegetation, snow, ice and water, in particular by developing and utilizing advanced airborne and space-based laser altimeter systems. He is principal investigator for the airborne Slope Imaging Multi-polarization Photon-Counting Lidar (SIMPL), developed through the NASA Instrument Incubator Program (IIP). The instrument is demonstrating measurement techniques enabling more capable spaceflight laser altimeters for future Earth science and planetary exploration missions. Harding was a member of the Ice, Cloud and land Elevation Satellite (ICESat) Science Team and ICESat-2 Science Definition Team. He is also Study Scientist for the Lidar Surface Topography (LIST) mission that the NRC recommended be conducted by NASA in their Earth Science Decadal Survey report. He was the science lead for the IIP Airborne LIST Simulator (ALISTS) that developed and advanced technoligies needed for mapping topography and vegetation structure from space. In addition, Harding was a founding member of, and represented NASA in, the Puget Sound Lidar Consortium (PSLC) that conducted comprehensive airborne lidar mapping in the Puget Sound region and Cascades Range, WA.

    Brief Bio

    Dr. David Harding conducts research in the topographic expression of land surface processes and the physical properties of vegetation, snow, ice and water, in particular by developing and utilizing advanced airborne and space-based laser altimeter systems. He is principal investigator for the airborne Slope Imaging Multi-polarization Photon-Counting Lidar (SIMPL), developed through the NASA Instrument Incubator Program (IIP). The instrument is demonstrating measurement techniques enabling more capable spaceflight laser altimeters for future Earth science and planetary exploration missions. Harding was a member of the Ice, Cloud and land Elevation Satellite (ICESat) Science Team and ICESat-2 Science Definition Team. He is also Study Scientist for the Lidar Surface Topography (LIST) mission that the NRC recommended be conducted by NASA in their Earth Science Decadal Survey report. He was the science lead for the IIP Airborne LIST Simulator (ALISTS) that developed and advanced technoligies needed for mapping topography and vegetation structure from space. In addition, Harding was a founding member of, and represented NASA in, the Puget Sound Lidar Consortium (PSLC) that conducted comprehensive airborne lidar mapping in the Puget Sound region and Cascades Range, WA.
