Glacier monitoring from in-situ and remotely sensed observations
Convener: Michael Zemp | Co-conveners: Bruce Raup, Hrafnhildur Hannesdóttir, Livia JakobECSECS

Process understanding is key to assessing the sensitivity of glacier systems to changing climate. Comprehensive glacier monitoring provides the base for large-scale assessment of glacier distribution and changes. Glaciers are observed on different spatio-temporal scales, from extensive seasonal mass-balance studies at individual glaciers to decadal assessments of glacier mass changes and repeat inventories at the scale of entire mountain ranges. Internationally coordinated glacier monitoring aims at combining in-situ measurement with remotely sensed data, and local process understanding with global coverage. We invite contributions from a variety of disciplines, from tropical to polar glaciers, addressing both in-situ and remotely sensed monitoring of past and current glacier distribution and changes, as well as related uncertainty assessments. A special focus of this session shall be on (i) strengths and limitations of different types of satellite data for regional and global assessments, (ii) achieving a better temporal resolution of regional and global assessments, (iii) how to develop in-situ networks for real-time monitoring of glacier changes, and (iv) advances in studies on local process understanding and how best to combine them with regional to global change assessments.
