Paul Rosen, PhD

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 …
