ResumoSatellite remote sensing is emerging as an important technology that will drive understanding of critical environmental science geared towards achieving the 17 Sustainable Development Goals of the United Nations. To help foster the Sustainable Development Agenda, experts across multidisciplinary fields of remote sensing are now working with end users in the application of remote sensing products to provide insights that underpin policies. New satellite sensors, including radar technology, have emerged to help improve science applications in key aspects of the environment, including the monitoring of groundwater, coastal wetlands, extreme events and hazards, snow/glaciers and ice sheets, forest ecosystems, soil moisture, permafrost, pollution, etc. In this chapter, the focus is on radar missions, given their sophistication and all-weather imaging capabilities. The novel NASA-ISRO SAR Mission (NISAR) has emerged as a sophisticated radar mission with broadened applications compared to other well-known radar systems. Among other things, the NISAR is discussed in detail, and its mission objectives, scope, and broad multidisciplinary capabilities in environmental assessment are highlighted. The potential of its combination with satellite gravity missions to improve the assessment of groundwater status and impacts associated with overabstraction is stressed.
