Keywords:outlet glacier, grounding line, Langhovde Glacier, DDInSAR

To identify a grounding line at the Langhovde Glacier in East Antarctica, "double differential interferometric SAR (DDInSAR) analysis" is performed using ALOS-2 / PALSAR-2 microwave data. By comparing the vertical component obtained by DDInSAR with the field survey data, we estimated position of a grounding line at the Langhovde Glacier.
