Abstract. Despite their importance for sea-level rise, seasonal water availability, and as a source of geohazards, mountain glaciers are one the few remaining subsystems global climate system which no globally applicable, open source, community-driven model exists. Here we present Open Global Glacier Model (OGGM), developed to provide modular open-source numerical framework simulating past future change any glacier in world. The modeling chain comprises data downloading tools (glacier...
Estimations of global glacier mass changes over the course 20th century require automated initialization methods, allowing reconstruction past states from limited information. In a previous study, we developed method to initialize Open Global Glacier Model (OGGM) climate information and present-day geometry alone. Tested in an idealized framework, this aimed quantify how much carries about states. The was not applied real-world cases, therefore, results were comparable with observations....

Abstract. To provide estimates of past glacier mass changes over the course 20th century, an adequate initial state is required. However, empirical evidence about states at regional or global scales largely incomplete, both spatially and temporally, calling for use automated numerical methods. This study presents a new way to initialize Open Global Glacier Model from climate information present-day states. We synthetic experiments show that even with these perfectly known but incomplete...
Peripheral glaciers (PGs, i.e., that are dynamically decoupled from the ice sheet) play a significant role in mass balance and freshwater runoff of Greenland's land ice. Their evolution has implications for sea level, global climate ocean circulation, as well coastal communities ecosystems. In order to accurately model contribution PGs overall supply, it is necessary consider their characteristics set them apart main sheet. this study, we used Open Global Glacier Model (OGGM) conduct...

However, empirical evidence about states at regional or global scale largely incomplete, both spatially and temporally, calling for use automated numerical methods. This study presents a new way to initialize Open Global Glacier Model from climate information present-day states. We generate large set physically plausible candidates given year in (e.g. 1850 Alps)....
<p> In order to assess glacier mass balance on large temporal and/or spatial scales, numerical modelling is an essential tool, complementing ground observations and remote sensing methods. For a reliable simulation of glacier’s development over time, knowledge its initial state fundamental. Attaining this information entirely through empirical evidence impossible due lack data, hence the need for alternative, study, three methods varying complexity are applied...
