Mining noise data for monitoring Arctic permafrost by using GNSS interferometric reflectometry
Ground surface elevation changes are closely linked to the dynamics of the active layer and near-surface permafrost. GNSS interferometric reflectometry (GNSS-IR), a technique utilizing reflected signals regarded as noise in the GNSS applications, such as positioning and navigation, can measure surfa...

Ground surface elevation changes are closely linked to the dynamics of the active layer and near-surface permafrost.
