Each glacier is defined separately in the inventory. Acquired by the Landsat 8 satellite on August 13, 2013, the image shows Alaska’s Battle Glacier Complex, which contains at least three glaciers. The inventory includes detailed outlines of the extent of each glacier-information that is critical in figuring out how much that glacier might contribute to rising sea levels. The true value of the Randolph Glacier Inventory is illustrated in the lower image. The map includes some 198,000 glaciers that cover approximately 726,800 square kilometers (280,600 square miles). Glaciers outline the world’s major mountain ranges and fringe the ice sheets of Antarctica and Greenland. The locations of glaciers are marked in blue. The top image shows the complete Randolph Glacier Inventory. The recently published Randolph Glacier Inventory is the first global catalog of glaciers, and it was developed to help IPCC scientists improve estimates of sea level rise. The biggest challenge in figuring out how much ice melt will cause sea levels to rise is the lack of information about how much ice glaciers currently hold, says the Intergovernmental Panel on Climate Change (IPCC). Sea levels are rising because water expands when it warms up, but also because ice has been melting. The flexible design of GLIMS make it easy to interface to other scales and instruments.Many of the world’s coastal cities and populations are vulnerable to rising sea levels, but just how vulnerable is a question scientists are trying to answer. If you have instruments not listed please contact us. GLIMS imports from the following air samplers: Anderson, R&P (manual and sequential) and BGI and GLIMS links to both the Mettler and Sartorius Scales. GLIMS generates reports in both delimitated and non-delimitated formats. GLIMS can then generate reports for AIRS, net weight, particulate concentrations, scale accuracy, and quality control information.

Additionally, full editing features allow the user to manually enter information directly into the database for documentation. The technician can import field sampler data into the database at this time.
When filters are returned to the laboratory, each filter is weighed again and the program records the gross weight. Sampler Run Data Sheets are printed to accompany filters out to the field. Temperature and relative humidity information can be viewed in a graphic display, allowing technicians to easily monitor lab conditions. This data can be used for documenting ambient conditions to support quality control reporting. Additionally, the program records temperature and relative humidity in the laboratory, via a data translator. The filter is placed on the scale and the program reads the tare weight of the filter, adding it to the database record. Developed as a custom solution for a research laboratory, GLIMS is now a commercial product used by State and County Air Quality Management Districts to manage their collection, measurement and reporting of particulate data.įor each filter, GLIMS creates a database record and optionally generates a bar coded label which is applied to a filter container (and can be scanned at any time to recall the database record).

GLIMS is a comprehensive Gravimetric Laboratory Information System that collects data from particulate dust monitors, reads filter labels via bar codes, records filter weights via a serial interface to a precision scale, collects temperature and humidity data required for quality assurance and creates formatted particulate air quality reports and quality assurance reports required by state and federal agencies.
