We investigated periods when unusually warm conditions in Patagonia occurred at the same time as precipitation events on the Antarctic Peninsula. By combining observations and simulations, we identified 127 such events between 1980 and 2022. These events increased ice melt in Patagonia while enhancing accumulation on the Antarctic Peninsula, highlighting how large-scale weather patterns can simultaneously affect ice-covered regions in different ways.

We studied how well a high-resolution weather model simulates atmospheric conditions over a glacier in the Austrian Alps. By comparing model results with extensive field observations from weather stations, lasers, and research drones, we found that the model accurately captures temperature, moisture, and wind patterns. Some errors remain close to the surface and during transitions of wind regimes. Overall, the model provides a reliable tool to support future climate and glacier research.

Glaciers in the European Alps are shrinking rapidly because of climate change. We developed a new open-source method that combines satellite observations with computer models to estimate where glaciers gain and lose ice. Applied to hundreds of glaciers, the results agree well with field measurements. This approach improves our understanding of glacier change and helps make more reliable predictions of their future.

Melting glaciers worldwide cause changes in land surface type and elevation that may impact regional climate. In a weather and climate model, we find that these changes result in warming and less precipitation, particularly less snow, over Jostedalsbreen ice cap in western Norway. Most of these impacts are related to thinning of the ice cap and the associated lowering of the surface and reduction in orographic lifting of moist air masses. The findings suggest accelerated melting of the ice cap.

Monthly frontal ablation is quantified at Svalbard tidewater glaciers from 2015–2024 using terminus positions derived from a segmentation model's predictions of satellite radar images. Our high spatio-temporal resolution results will improve the process understanding of frontal ablation, provide reference data for the modeling community, and deliver an ideal dataset for studying controls of frontal ablation.

Snowpack dynamics in the Southern Andes remain poorly quantified due to sparse and inconsistent in situ data, limiting hydrological modeling. We compile and quality-control daily snow depth observations from 81 stations (21–54° S, 2010–2024). The resulting dataset improves the Physical Consistency Index (up to 95 %) despite reduced data availability, reveals a north–south increase in snow depth with nonlinear elevation patterns, and represents the most complete regional dataset to date.

We studied how a glacier in the Austrian Alps moves more slowly over time due to climate change. By combining long-term field data with recent aerial images, we show how thinning reduce glacier flow. Our findings help understand changes in glacier behavior in a warming climate.

Our study focused on understanding how a warming climate affects the Aletsch glacier accumulation area. We used multi-year radar measurements and direct firn‑core analyses to estimate changes in density, layering, and compaction of snow-to-ice over a year. Our results show that the upper layers of the glacier are changing faster due to stronger summer melt in the lower parts of the accumulation zone. Our findings help to improve firn densification models and glacier mass-balance estimation.

Measurements of glacier snow line altitudes (transition between ice and snow) provide information to constrain surface mass balance modelling. This study presents a database of ~200,000 snow lines from glaciers in the European Alps (2000–2025). Exposed ice and snow are automatically classified using adaptive thresholding of surface reflectance in visible and infrared spectra. Since 2000, we observe an increase in late summer snow lines of ~150 m, indicating widespread melt at high altitudes.

We present the testing and implementation of a calving framework for simulating the evolution of glacier fronts in grounded glacier tongues. The approach is coupled with a level set method to track changes in the glacier front over time and with an eigen-calving law that allows calving to respond to ice flow and stress conditions. The framework is evaluated using a synthetic glacier domain and, when applied to marine-terminating glaciers in Svalbard, reproduces observed calving front patterns.

Ecohydrological processes in heavily managed catchments are often inadequately represented in models. We applied a tracer-aided model STARR (Spatially distributed Tracer-Aided Rainfall-Runoff) in an ET (evapotranspiration)-dominated region (the Middle Spree, NE Germany) with major management impacts. Water isotopes were useful in identifying runoff contributions and partitioning ET even at sparse resolution. Trade-offs between discharge- and isotope-based calibrations could be partially mitigated by integrating more process-based conceptualizations into the model.

Satellite altimeters only sample surface heights at scattered points. We developed a method to turn these measurements into maps of glacier height change while also estimating how reliable the results are. Applying this approach to glaciers in Svalbard and Antarctica shows strong ice loss and clearly captures short-lived events such as glacier surges. Our results improve the ability to monitor glacier change in difficult terrain and help better assess future contributions to sea level rise.

We reconstruct historical topography for a rapidly warming Antarctic region with limited existing data. Using approximately 2000 aerial photographs from the year 1989 over the western Antarctic Peninsula and nearby islands, we created detailed elevation models and orthoimages that have high accuracy compared to recent satellite data. This open dataset aids tracking historical ice loss and its role in sea level rise.

Short summary
The Southern Patagonian Icefield is losing glacier area and ice volume rapidly. Although its glaciers share the same plateau, they retreat at different speeds and times. One reason for these differences lies in the unknown landscape beneath the ice. To reveal it, we used helicopter-based radar to measure the ice thickness and map the bedrock of Viedma, Upsala, and Perito Moreno Glaciers.

We present MATILDA-Online, an open-source, cloud-based modeling toolkit, to support integrated water management in glacierized mountain regions. It integrates glacier and hydrology models with open data and cloud computing. Despite data scarcity, this tool empowers local professionals, students, and researchers to generate climate impact assessments, promoting informed decision-making. Despite its accessibility, effective calibration and interpretation still require expert knowledge.

This study examines water resources in a high-mountain basin in Kyrgyzstan facing climate change. The applied MATILDA-Online toolkit aims to integrate scientific research with practical water management. Projections indicate severe glacier melt and a significant reduction in runoff by 2100, with earlier peak flows and increased dry periods. The main challenges are the limited number of observations and their low accuracy, as well as the substantial effort required for model calibration.

We studied how the density of snow to ice transition varies with depth in the Aletsch glacier using radar-based field measurements and some simple models. We showed that it is possible to track how much snow has accumulated in the last 10–14 years. This helps improve the uncertainties in glacier mass balance estimates. Overall, by utilising non-invasive radar techniques and models, we provide a novel approach to understanding the evolution of glaciers under regional climate conditions.

In this paper, we present a ready-to-use benchmark dataset to train machine learning approaches for detecting ice thickness from radar data. It includes radargrams of glaciers and ice sheets alongside annotations for their air–ice and ice–bedrock boundary. Furthermore, we introduce a baseline model and evaluate the influence of several geographical and glaciological factors on the performance of our model.

As climate change escalates, the Berlin-Brandenburg region faces new challenges. Climate change-induced extreme events are expected to cause new conflicts to emerge and aggravate existing ones. To guide future research, we co-develop a list of key questions on climate and water challenges in the region. Our findings highlight the need for new research approaches. We expect this list to provide a roadmap for actionable knowledge production to address climate and water challenges in the region.

Glacial lake outburst floods (GLOFs) continue to threaten high-mountain communities in Nepal. We simulate potential GLOF events from five glacial lakes in the Everest region during the 21st century using a 3D flood model and several breach and SSP scenarios. Large GLOFs could extend over 100 km and inundate 80 to 100 km of roads/trails, 735 to 1989 houses and 0.85 to 3.52 km2 of agricultural land. The results help to assess the changing GLOF impacts and support more accurate risk assessments.

The Northern Patagonian Icefield is the second largest ice mass of South America, located at moderate latitudes. Using an ice-flow model which uses available atmosphere data as input and explicitly models iceberg discharge, we assess its evolution. With present climate, it will lose about 25 % of its mass during this century. Climate change strongly accelerates losses and under Paris Agreement compliance it is 36 % until 2200 and up to 68 % under a business-as-usual fossil fuel scenario.

The 1987 Parraguirre ice–rock avalanche developed into a devastating debris flow, causing the loss of many lives and inflicting severe damage near Santiago, Chile. Here, we revise this event, combining various observational records with modelling techniques. In that year, important snow cover coincided with persistent warm periods in spring. We also put forward upward corrections for the trigger and flood volumes involved in this debris flow. Finally, temporary river damming was key for the flow ferocity.

In the present work, we provide a new ice thickness reconstruction of the Antarctic Peninsula Ice Sheet north of 70º S using inversion modeling. This model consists of two steps: the first uses basic assumptions of the rheology of the glacier, and the second uses mass conservation to improve the reconstruction where the assumptions made previously are expected to fail. Validation with independent data showed that our reconstruction improved compared to other reconstructions that are available.

The estimation of the amount of water found within supraglacial lakes is important for understanding how much water is lost from glaciers each year. Here, we develop two new methods for estimating supraglacial lake volume that can be easily applied on a large scale. Furthermore, we compare these methods to two previously developed methods in order to determine when it is best to use each method. Finally, three of these methods are applied to peak melt dates over an area in Northeast Greenland.

Satellites have made it possible to observe glacier elevation changes from all around the world. In the present study, we compared the results produced from two different types of satellite data between different research groups and against validation measurements from aeroplanes. We found a large spread between individual results but showed that the group ensemble can be used to reliably estimate glacier elevation changes and related errors from satellite data.

Through a physical model, we explored how lacier geometry and topography configuration constrains glacier thinning in the Patagonian Icefields, the world's main glacial freshwater reservoir after Antarctica and Greenland. Our results indicate that about 53 % of the Patagonian Icefield ice flow is susceptible to thinning. Our findings allow for identifying priority glaciers for future research considering climate change projections.

Delineating calving fronts of marine-terminating glaciers in satellite images is a labour-intensive task. We propose a method based on deep learning that automates this task. We choose a deep learning framework that adapts to any given dataset without needing deep learning expertise. The method is evaluated on a benchmark dataset for calving-front detection and glacier zone segmentation. The framework can beat the benchmark baseline without major modifications.

Existing mass budget estimates for the northern Antarctic Peninsula (>70° S) are affected by considerable limitations. We carried out the first region-wide analysis of geodetic mass balances throughout this region (coverage of 96.4 %) for the period 2013–2017 based on repeat pass bi-static TanDEM-X acquisitions. A total mass budget of −24.1±2.8 Gt/a is revealed. Imbalanced high ice discharge, particularly at former ice shelf tributaries, is the main driver of overall ice loss.

Knowledge on the volume of glaciers is important to project future runoff. Here, we present a novel approach to reconstruct the regional ice thickness distribution from easily available remote-sensing data. We show that past ice thickness, derived from spaceborne glacier area and elevation datasets, can constrain the estimated ice thickness. Based on the unique glaciological database of the European Alps, the approach will be most beneficial in regions without direct thickness measurements.

Ice loss of glaciers shows in retreating calving fronts (i.e., the position where icebergs break off the glacier and drift into the ocean). This paper presents a benchmark dataset for calving front delineation in synthetic aperture radar (SAR) images. The dataset can be used to train and test deep learning techniques, which automate the monitoring of the calving front. Provided example models achieve front delineations with an average distance of 887 m to the correct calving front.

Radiative transfer processes are the main energy transport mechanism in urban areas which influence the surface energy budget and drive local convection. We show here the importance of each process to help modellers decide on how much detail they should include in their models to parameterize radiative transfer in urban areas. We showed how the flow field may change in response to these processes and the essential processes needed to assure acceptable quality of the numerical simulations.

Short summary
Arctic glaciers have been subject to extensive warming due to global climate change, yet their contribution to sea level rise has been relatively small in the past. In this study we provide mass changes of most glaciers of the Russian High Arctic (Franz Josef Land, Severnaya Zemlya, Novaya Zemlya). We use TanDEM-X satellite measurements to derive glacier surface elevation changes. Our results show an increase in glacier mass loss and a sea level rise contribution of 0.06 mm/a (2010–2017).

Short summary
Short summary
Consistent and continuous data on glacier surface velocity are important inputs to time series analyses, numerical ice dynamic modeling and glacier mass flux computations. We present a new data set of glacier surface velocities derived from Sentinel-1 radar satellite data that covers 12 major glaciated regions outside the polar ice sheets. The data comprise continuously updated scene-pair velocity fields, as well as monthly and annually averaged velocity mosaics at 200 m spatial resolution.

Short summary
Calibration of surface mass balance (SMB) models on regional scales is challenging. We investigate different calibration strategies with the goal of achieving realistic simulations of the SMB in the Monte Sarmiento Massif, Tierra del Fuego. Our results show that the use of regional observations from satellite data can improve the model performance. Furthermore, we compare four melt models of different complexity to understand the benefit of increasing the processes considered in the model.
