This paper is about looking at change in the Cordillera Blanca glaciers by comparing GLIMS data to historical data. World Glacier Monitoring Service (WGMS) – established in 1986 but since then glaciers became part of the Global Climate Observation System (GCOS) and the Global Hierchical Observation Strategy (GHOST) which are both programs operated by the World Meteorological Organization (WMO), the Intergovernmetal Oceanographic Commission (IOC), the International Council of Scientific Unions (ICSU), and the United Nations Environment Programme (UNEP). I was able to access the NSIDC glacier viewer though and will look at this further. NSIDC has a great graphical interface (GISMO) for obtaining data but I need to be on Windows to use. There are also places in the metadata table for each glacier for error such as absolute and relative. The GLIMS glacier database is an extention of the World Glacier Inventory (WGI) that is meant to add snapshots over time. If glaciers split there is a field in the database table to show parent glacier as well. Main product of project is the Glacier Database which can be accessed online. Coordinated by the University of Arizona. Data is received by the Global Land Ice Management from Space (GLIMS) Project team at the National Snow and Ice Data Center (NSIDC) in Boulder. Goal is to use multispectral satellite imagery to inventory glaciers and understand change in terms of climate and other env. “Stewards” are responsible for individual glaciers. Each center is responsible for a certain subregion. Each institution is called a regional center. ![]() 60 institutions world wide with goal to inventory world’s estimated 160,000 glaciers.

These maps are similar to the existing Randolph Glacier Inventory (RGI) data sets, but are created on-demand from the full multi-temporal GLIMS Glacier Database. The glacier database of the Global Land Ice Measurements from Space (GLIMS) initiative is the only multi-temporal glacier database tracking all these glacier measurements and providing them to the scientific community and broader public.Here we present a new tool for extracting global glacier maps representative of arbitrary years. To understand these impacts and the processes behind them, it is crucial to monitor glaciers through time by mapping their areal extent, changes in volume, elevation distribution, snow lines, ice flow velocities, and changes to associated water bodies. Glacier losses have impacts on local water availability and hazards, and contribute to sea level rise. ![]() Abstract: Glaciers are shrinking in most regions of the world.
