The data descriptor represents a Germany-wide and spatio-temporally consistent 1 x1 km² analysis-ready time series of interpolated days of the year (DOYs). The data set covers 56 entry dates of phenological development stages of 9 main crop types for the period between 1993 and 2021. The derivation of the 1624 records is based on phenological observations provided by German Meteorological [...]

Groundwater overexploitation has been cited as one of the biggest threats to rural drinking water in India, but there is very little quantitative evidence. In this paper, we aim to understand (1) the extent of actual groundwater depletion and its impact on rural drinking water supply systems, (2) the primary driver of groundwater depletion and (3) the additional financial burden in finding new [...]

Lake Surface Temperature (LST) is a key characteristic that reflects meteorological and climatological influences on lakes. In general, there is limited LST data from high elevation lakes available as these areas are remote and not part of regular monitoring programs. Nonetheless, it is crucial to understand their response to climate warming for the development of effective management strategies [...]

The Vertical Seismic Profile (VSP) is a widely used technique for extracting velocity information and seismic well tie purposes. However, the full potential of VSP data remains underutilized. This study explores the broader applicability of VSP data beyond its conventional usage by investigating its benefits for seismic data processing and interpretation. Advanced VSP products, incorporating [...]

The process of macroplastic (>0.5 cm) fragmentation results in the production of smaller plastic particles (micro- and nanoplastics), which threaten biota and human health and are difficult to remove from the environment. The global coverage and long retention times of macroplastic waste in fluvial systems (ranging from years to centuries) create long-lasting and widespread potential for its [...]

Methane is large contributor to climate change; for this reason, detecting and eliminating sources of methane emissions is a key element to minimizing the effects of on-going climate change. While there are a variety of methods currently used to detect methane emissions, ranging from ground-based sensors to aerial sensors like drones and aircraft, satellite detections provide a broad-area [...]

One of the most remarkable features of the central Northern Calcareous Alps (Eastern Alps, Austria) is the widespread presence of Upper Triassic deep-water carbonates and Permo-Triassic evaporites resting on deep-water Middle Jurassic sediments and their underlying Upper Triassic shallow-water carbonate platform successions. The Triassic deep-water carbonates and accompanying evaporites have been [...]

We utilised repeat high-resolution UAV-SfM surveys, alongside terrestrial photography acquired in-situ, to investigate, for the first time, the role of thermal notch erosion in forcing localised calving failure and subsequent short-term increases in velocity at a lake-terminating glacier. This data was acquired daily (where possible) across one week in July 2019 and two weeks in July 2021 to [...]

Transients of aseismic fault slip, slow slip events (SSEs), have been observed in spatial and temporal proximity to the initiation of megathrust earthquakes. However, the underlying physics potentially connecting a preceding SSE to earthquake rupture remains to be determined. Here, we link 3D observation-driven slow-slip cycle models with dynamic rupture simulations of the 2014 Mw7.3 Guerrero, [...]

Global mean sea-level (GMSL) change can provide insight on how ice sheets, glaciers, and oceans respond to warming[1;2]. The Holocene (11.7 ka to present) marks a time when temperatures may have exceeded early industrial (1850 CE) values[3]. Evidence from Greenland[4] and Antarctica[5;6] indicates that both ice sheets retreated inland of their present-day extents during the Holocene, yet previous [...]

The terrestrial carbon cycle varies dynamically over short periods that can be difficult to observe. Geostationary (“weather”) satellites like the Geostationary Environmental Operational Satellite - R Series (GOES-R) deliver near-hemispheric imagery at a ten-minute cadence, and its Advanced Baseline Imager (ABI) measures visible and near-infrared spectral bands that can be used to estimate land [...]

Global temperatures are rising. This paper demonstrates for the first time that the global temperature increase has not been linear but is exponential with a doubling time of about 25 years. Both the amount of carbon dioxide produced by the combustion of fossil fuels and the amount of carbon dioxide in the atmosphere have also risen exponentially, with a similar doubling time. The exponential [...]

The Anthropocene is the present time of human-caused accelerating global change, and new forms of Anthropocene risk are emerging that society has hitherto never experienced. Science and policy are grappling with the temporal and spatial magnitude of these changes, as well as the diminishing margin between science and policy itself. However, there is a gap in the transparency — and perhaps even in [...]

Much work has been done to build arrangements between volcanology and meteorology to handle the aviation risks from volcanic ash. This workshop will discuss how to approach collaborative arrangements for other volcanic hazards to the public, particularly where a multi-disciplinary approach is required. These hazards include tsunamis, ashfall, rainfall-induced dome collapses, lahars, pumice, [...]

Climate change and unabated greenhouse gas emissions are increasing the possibility that the world will turn to climate intervention to curb ever-increasing global temperatures. To date, most work on this topic has imagined that an international organization like the United Nations or an international coalition of states will synchronize their efforts to deploy climate intervention at ideal [...]
