IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, Vol 17, Pp 14874-14893 (2024)
For high spatiotemporal resolution global navigation satellite system interferometric reflectometry (GNSS-IR) snow depth monitoring, addressing terrain effects and multi-GNSS data fusion together is essential due to their coupling. Analyzed multi-GNS
