The P-band radar completed the Alaska permafrost observation last weekend.  In addition, the radar made two observations over the Sitka landslide area in the southeastern tip of Alaska on August 28 and 31 respectively.  The crossing flight lines are shown in the graphics below and we will attempt to reconstruct the 3-dimensional deformation signals from interferometric data sets acquired 3 days apart.  Repeat-pass interferometry with the P-band radar has recently been demonstrated with data acquired in Harvard Forest.  In addition, polarimetric data products can be used to detect geophysical changes in the forest landscape such as landslides and rotation of forest stands.
