measurements from Space project What about Debris covered glaciers? Literature Overview Project to monitor the worlds changing glaciers mountain glaciers, one of the most natural indicators of climate change NDVI has been used by Paul et al (2004) to help map the vegetation surrounding the glacier
Ranzi et al (2004) recognized a reduction in which thermal was effective (0.5m) on the Miage Glacier
Areas close to the terminus where periglacial debris was 1m+ thick showed higher temperatures
Also applied a field study for glacier outlines (Foster Et al 2009; Haeberli et al 1999; Paul et al 2004; Svoboda & Paul 2009) METHODOLOGY NDVI
