The data acquired through S-band and L-bandR from a single platform will help the scientists to understand the changes happening to Earth.According to ISRO, the NISAR mission’s primary objectives are to study land and ice deformation, land ecosystems, and oceanic regions in areas of common interest to the US and Indian scientific communities.The mission would help in measuring the woody biomass, track changes in the extent of active crops, understand the changes in wetlands extent among others.The mission life of NISAR is 5 year.NASA said the data from NISAR mission would provide critical insights to help governments and decision-makers plan for natural and human-caused hazards.NISAR can help with hazard-monitoring efforts and potentially give decision- makers more time to prepare for a possible disaster.The RADAR satellite would provide a 3D view of the Earth’s land and ice and through its ability to see through clouds and light rain, day and night, the satellite would enable data users to continuously monitor earthquake and landslide prone areas and determine how quickly glaciers and ice sheets are changing.The data collected from the satellite would also offer an ‘unprecedented coverage of Antarctica, an information that would help with studying how the continent’s ice sheet changes over time.Significantly, NISAR is the most advanced radar system ever launched by NASA or ISRO and it would generate more data on a daily basis than any previous Earth satellites launched by them.The NISAR mission would help the two space agencies to monitor ecosystems around the world and the L band penetrates deep into forest canopies, providing insights into forest structure, while the S-band radar is monitoring crops.The NISAR data would help researchers assess how forests, wetlands, agricultural areas change over time.
