data submission

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.

call-for-data now open!

Deadline for data submission: Dec 1, 2021.

For the submission of glacier fluctuation data (i.e., changes in length, area, volume, and mass), please carefully read the FoG submission instructions.

  • WGMS (2021, updated from earlier versions): FoG submission instructions. World Glacier Monitoring Service, Zurich, Switzerland: 41 pp. [pdf]

To submit data with the help of a template, you can either edit a copy of the Google Sheets or download the Microsoft Excel file:

Google Sheets template: Digital Data Submission Form. World Glacier Monitoring Service, Zurich, Switzerland. [link]

  • Make and open your own copy of the template (you will be prompted to sign in to your Google account if not already). This copy will be stored in the Google Drive of your Google account.
  • Fill out the template. Dropdowns, automatic validation, and red highlighting will help you catch errors as you work. Hover over a column name for additional information about that column.
  • IMPORTANT – The template relies on formulas, data validation, and formatting to function. If using copy-paste, paste values only:
    • Windows: Edit > Paste special > Paste values only (Control-Shift-V)
    • Mac: Edit > Paste special > Paste values only (Command-Shift-V)
  • To submit, share it with the WGMS: Share > Add people and groups > wgms@geo.uzh.ch (as editor)

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 fifth issue of the Global Glacier Change Bulletin (2020-2021).

For considering an inclusion of your glacier in the Detailed Information Section of the upcoming GGCB, we need the following additional information:
– full mass balance details (i.e. seasonal/annual balances, ELA, AAR, balance distribution with elevation, point balances) for 2019/20 and 2020/21,
– overview photograph (at least 600 dpi) from the glacier in 2020 or 2021, including date and referenced by author,
– three maps of around A4-size showing the outlines of the glacier, the scale, the direction to North and (a) topography and observation network, (b) annual balance distribution for 2019/20, and (c) annual balance distribution for 2020/21,
– short text commenting on the general characteristics of the glacier and the reported balance years; the text should include information on: glacier extent and size, inter-/extrapolation methods, available geodetic surveys, mean annual air temperature and annual precipitation at ELA, remaining ice thickness, etc.
The last issue of the GGCB might serve you as an example during the data preparation.

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!
