GCW/SLF software package

WMO Global Cryosphere Watch (GCW) is depending on a number of observing stations (CryoNet stations) for feeding the GCW value chain with observations. GCW has a requirement for both real time and archived data. In the period 2015-2017, GCW has been working with WSL/SLF to set up interoperability between the WSL/SLF data centre being responsible for one of the CryoNet stations. WSL/SLF has kindly agreed to make the software stack they have developed available for a wider community.

Under development

The old GCW Data Portal is available at This portal is still under development and active content management has yet not started. The Global Cryosphere Watch catalogue is yet not considered an operational service. It is populated with metadata harvested from a number of contributing data centres, but data remains in the original location and are served through the interfaces supported by the originating data centre.

The concept of metadata

GCW Portal metadata are divided in 4 categories which are briefly described in Table 1. Among these 4 categories, data providers or supporting data centres are supposed to provide 3 of them. Further below in this document, there are recommendations on how to provide these.

Table 1: Brief introduction to different types of metadata.





Contributing data centres

An overview of the contributing data centres is provided in the illustration below. Not all data centres are fully integrated, but discussions on how to integrate have been initiated.
