Towards Establishment of Ground Measurement Sites Network in India For Validation of NISAR Ecosystems Science Products
The NASA-ISRO Synthetic Aperture Radar (NISAR) is an Indo-US collaborative mission planned for launch in early 2025. Once deployed, NISAR will be a powerful and unique Earth-orbiting radar instrument that will provide L and S band dual-frequency SAR data with high repeat cycle (12 days exact repeat orbit), high resolution (3-10 meters range resolution) and large swath ($\gt240 \mathrm{~km}$), with capability of acquiring full-polarimetric and repeat-pass interferometric data [1], [2]. NISAR systematic observation at L-band and Sband over Indian region will provide very valuable timeseries data for the ecosystem sciences addressing the critical issues of forest carbon stock estimation and monitoring carbon fluxes from vegetation disturbances; agriculture crop monitoring and changing cropping patterns; spatio-temporal distribution of field-scale soil moisture and inundation dynamics of wetlands. Accordingly, several ecosystems science products have been planned from NISAR as value added products or NISAR Level-4 science products to be used as input for climate change models, various land-based applications and decision support systems. In order to ensure that the products meet the desired accuracy levels, extensive in situ measurements from a network of ground validation sites has been planned for calibration and validation of these products. This paper provides an overview of the ground measurement sites network established in India for calibration and validation of NISAR Ecosystems Science products being developed for the Indian region.
