TitleLong-term monitoring of the Inylchek glacier's surface kinematics

SummaryWith the help of ascending and descending high-resolution Terra-SAR data, we would like to monitor the surface velocity of the Inlychek glacier, located within the Tien Shan mountain range in Central Asia. By acquiring continuous scenes for every 11 days of the entire glacier, we are able to do a seasonal time series analysis that we will compare to our findings from the feasibility study from 2009 and 2010. Our major research topic is the investigation of the impact of the kinematics on the annually occurring GLOF (glacial lake outburst failure) event of adjacent Lake Merzbacher. Processing of the data is undertaken by the Amplitude Tracking method. We will validate our results by in-situ data (GPS and ablation measurements) gained through a field work campaign, which takes place in summer 2012. Additional comparisons with results gained from Landsat data and Rapid Eye data is also in preparation. To start long-term monitoring, we request 2 adjacent ascending and 3 adjacent descending StripMap scenes (single polarisation HH) over the same track for every 11 days, covering the test site for three entire years (2012-2015). Our investigations are part of the PROGRESS project (Potsdam Research Cluster for Georisk Analysis Environmental Change and Sustainability), which is funded by the German Ministry of Education and Research (BMBF).
