The WGMS regularly compiles and publishes standardized data on glacier changes in length, area, volume, and mass based on in-situ and remotely sensed observations. A corresponding call-for-data is annually sent out through the National Correspondents of the WGMS who organize the collection and submission of the glacier data within their country. Apart from the official calls-for-data, the WGMS welcomes any glacier data that is submitted according to the standards described below.
The next call-for-data will be in autumn 2018!
For the submission of glacier fluctuation data (i.e., changes in length, area, volume, and mass), please carefully read the Notes on the Completion of the Data Sheets and use the excel-based Digital Data Submission Form of the WGMS.
The progress of data submission can be followed directly on our website.
Based on the received data we will update our online products and start the preparations for the third issue of the Global Glacier Change Bulletin (2016-2017). This new publication series merges the former “Fluctuations of Glaciers” and “Glacier Mass Balance Bulletin” series and aims at providing a more integrative assessment of worldwide and regional glacier changes, improving the visibility of our scientific collaboration network, and optimizing our reporting procedures.
For the submission of glacier reconstructions (i.e., front variation series), more information can be found here.
For the submission of other glacier datasets (i.e., inventory, photographs) please check the GTN-G website!
If you have any further questions concerning the data submission, please do not hesitate to contact us!
