SummaryThe cryosphere plays an important role in the Earth system. Glacier in the Greenland and Antarctica (Especially Jakobshavn and Pine Island Glacier) have been identified as sensitive indicators of global climate change. As a team with vast experience in InSAR and SBAS (or STBAS) for geophysical parameter retrieval, we propose to monitor seasonal change of glacial movement using multi-temporal TerraSAR-X images. We propose to use the TerraSAR-X (mainly stripmap mode) to monitor glacier movement over the Greenland and Antarctica. The aim is to detect possible significant dynamic change of glacier overtimes, which is related to global and seasonal climate change. A time-series of glacier movement can show seasonal effect or interesting trend over the periods, which will enable us to detect and better understand environmental phenomena that may affect to climate change. The Korea Polar Research Institute (KOPRI) has been performing such campaigns every year using ARAON, which is a Korean icebreaker,for scientific research in the polar region. The ARAON provides logistics to polar research stations and carries state-of-the-art research equipment for conducting geophysical, biological, oceanographic research. Both space-based and icebreaker ship-based measurements will provide complementary cooperation in scientific and practical use.
