Description:
Satellite observations have pushed glacier monitoring to truly global scales and resulted in reconciled estimates of glacier mass changes and its contributions to global sea-level rise. However, the latest IPCC assessment reports (IPCC SROCC and AR6) highlighted the shortcomings of the current methods: while an increasing number of regional estimates from various sources are now becoming available, there are large variations between these assessments, beyond stated uncertainties. This calls for a coordinated intercomparison exercise of regional glacier mass changes from glaciological in-situ measurements and various remote sensing sources, including geodetic DEM differencing, altimetry, and gravimetry. The present networking event will introduce a corresponding project, collect different views from related organizations, and calls for feedback and participation from the glaciological community.
