Fluctuations of Glaciers (FoG)
Listed in NASA Earthdata CMR
Since the beginning of internationally coordinated systematic observations on glacier variations in 1894, a valuable and increasingly important data basis on glacier changes has been built up.
Description
In 1986 the World Glacier Monitoring Service (WGMS) started to maintain and continue the collection of information on ongoing glacier changes, when the two former ICSI services PSFG (Permanent Service on Fluctuations of Glaciers) and TTS / WGI (TemporalTechnical Secretary / World Glacier Inventory) were combined.
The tasks of the WGMS are to continuously upgrade, collect and periodically publish glacier inventory and fluctuation data as well as to include satellite observations of remote glaciers and to assess ongoing changes. The WGMS database stores two types of data: 1) The World Glacier Inventory (WGI) contains glacier data describing the spatial distribution and 2) The Fluctuations of Glaciers (FoG) and Mass Balance Bulletin (MBB) contains data documenting changes in time (changes in mass, volume, area and length of glaciers).Today, the World Glacier Monitoring Service (WGMS) collects standardized observations on changes in mass, volume, area and length of glaciers with time (glacier fluctuations), as well as statistical information on the distribution of perennial surface ice in space (glacier inventories).

Such glacier fluctuation and inventory data are high priority key variables in climate system monitoring; they form a basis for hydrological modelling with respect to possible effects of atmospheric warming, and provide fundamental information in glaciology, glacial geomorphology and quaternary geology. The highest information density is found for the Alps and Scandinavia, where long and uninterrupted records are available.
