Josef Kellndorfer, PhD

Josef Kellndorfer heartily remembers receiving computer hard drives in the mail containing the data he needed for his research in the 1990s.

Those hard drives came from the Alaska Satellite Facility (ASF), traveling the roughly 4,400 miles to Massachusetts, where he worked at the Woods Hole Research Center, now known as the Woodwell Climate Research Center. Today he is a distinguished visiting scientist at the center but maintaining a strong connection to the satellite facility.

Things have changed mightily since those hard-drive days. He now gets the data he needs from the ASF by tapping on his computer keyboard.

He has been an integral player over his years of official and unofficial connection to the ASF Distributed Active Archive Center (DAAC), which is funded by NASA and part of the University of Alaska Fairbanks Geophysical Institute. And it has shown in the sharp increase in the number of researchers acquiring the data. They tap in from around the globe.

Josef is among the people who they can thank for that.

Paul Rosen, PhD

Dr. Paul Rosen is Project Scientist for the NASA-ISRO SAR (NISAR) mission. NISAR will measure Earth’s changing ecosystems, dynamic land surfaces, and ice masses, providing critical measurements for carbon cycle modeling, natural hazards research, sea level rise, groundwater exploitation, and more. With its all-weather, day/night, multi-frequency, polarimetric capability, NISAR will also support a host of other applications.

Dr. Rosen is applying 35 years of experience in Earth and planetary radar remote sensing to guiding NISAR science and the potential benefits and impact of these data in the science and applications community. This entails interacting with scientists, engineers, managers, and the public, at all levels and in many capacities. He expects NISAR to have a major impact on how science and applications are developed using synthetic aperture radar (SAR) data, noting that NISAR will provide the world with an unprecedented source of data, processing tools, and educational materials. NASA’s Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC) will take a leading role in NISAR data distribution and education.

Bernd Scheuchl, PhD

Bernd Scheuchl brings more than 25 years of experience using synthetic aperture radar remote sensing data in both industry and academia to his role as the chair of ASF’s User Working Group. As leader of the advisory board, he helps shape ASF’s role as a NASA Distributed Active Archive Center, ensuring the data are accessible for all users. Scheuchl works to coordinate ASF’s support of the upcoming NASA/ISRO SAR mission (NISAR) through development of new SAR techniques and transformative technology. As a researcher, his team’s work is at the forefront of using SAR data to study Antarctica, including producing its first continent-wide ice velocity map.

Dr. Nettie La Belle-Hamer

As Director of ASF, Dr. Nettie La Belle-Hamer’s mission is to support and mentor her team of driven professionals as leaders in remote sensing and data accessibility. She applies her research background in space physics to guide the facility as it provides high-quality data to meet the evolving needs of its users. Dr. La Belle-Hamer has been a part of ASF for 19 years and was appointed Director in 2002. She is also Deputy Director of the Geophysical Institute, where she works to develop and expand the capabilities of both organizations.

Franz Meyer, PhD

As ASF Chief Scientist, Franz J. Meyer leverages almost two decades of remote sensing research experience to act as the interface between ASF and the scientific community. 

Meyer has spent his career working with space agencies around the world to develop processing techniques and methods for synthetic aperture radar, or SAR, data. These techniques have been used to explore signals related to surface deformation such as earthquakes and volcanic eruptions. Recently, his research has expanded into the development of remote sensing-based hazard monitoring. He has led trainings around the world to help governments and organizations increase their capacity for radar techniques and hopes to transform SAR into a tool to meaningfully influence people’s lives on a daily basis.
