Isro unveils first Nisar S-Band radar dataset, shares sample images
ISRO has released the first batch of S-Band radar data from the NASA-ISRO Synthetic Aperture Radar (NISAR) mission via the Bhoonidhi portal. The satellite uses advanced dual-frequency radar technology to monitor environmental changes like ice movement, coastal wetlands, and irrigation patterns.
Why it matters
This mission provides high-resolution, consistent global data that is critical for climate change research, disaster management, and precision agriculture.
Bengaluru: Isro has released the first batch of S-Band radar data from Nasa-Isro Synthetic Aperture Radar (SAR), or Nisar mission, making it publicly available through Bhoonidhi portal.The space research agency also shared sample images from Tamil Nadu (Nagapattinam), Antarctica, Assam (Brahmaputra basin), Idaho, Greenland and Indonesia, highlighting the radar’s ability to track coastal wetlands, map irrigation patterns and monitor ice movement.The images underscore Nisar’s relevance to both scientific research and resource management, including coastal planning, precision farming and disaster monitoring.Nisar is a joint mission between Nasa and Isro and the first spaceborne radar to carry two frequency bands — L-band and S-band — on a single satellite.
