InSAR, also known as Interferometric Synthetic Aperture Radar, is a highly effective tool for remotely tracking changes in the Earth's surface using satellite-based radar. However, its accuracy can be affected by thick vegetation or snow cover. To address this issue, specialized InSAR satellites with L-band technology utilize longer wavelengths that can penetrate through vegetation, but their measurements may not be as precise as those taken by InSAR satellites with shorter wavelengths. In areas with heavy snow, InSAR monitoring is typically halted during the winter season, but data collected before and after this period can be used to fill in the gap. In our blog post, “How vegetation and snow impact InSAR readings”, we examine some of the considerations when using InSAR to monitor difficult terrain.
