Global 1km Land Surface Parameters for Kilometer-Scale Earth System Modeling
Published: 2023-06-28
Subjects: Atmospheric Sciences, Biogeochemistry, Climate, Earth Sciences, Hydrology, Meteorology, Oceanography and Atmospheric Sciences and Meteorology
Earth system models (ESMs) are progressively advancing towards the kilometer scale (k-scale). However, the surface parameters for Land Surface Models (LSMs) within ESMs running at the k-scale are typically derived from coarse resolution and outdated datasets. This study aims to develop a new set of global land surface parameters with a resolution of 1 km for multiple years from 2001 to 2020, [...]
Near-surface characterization using Distributed Acoustic Sensing in an urban area: Granada, Spain
Published: 2023-06-28
Subjects: Earth Sciences
The Granada Basin in southeast Spain is an area of moderate seismicity. Yet, it hosts some of the highest seismic hazards in the Iberian Peninsula due to the presence of shallow soft sediments amplifying local ground motion. In urban areas, seismic measurements often suffer from sparse instrumentation. An enticing alternative to conventional seismometers is the Distributed Acoustic Sensing (DAS) [...]
Single-blind test of nine methane-sensing satellite systems from three continents
Published: 2023-06-28
Subjects: Atmospheric Sciences, Other Civil and Environmental Engineering
Satellite-based remote sensing enables detection and mitigation of large point sources of climate-warming methane. These satellites will have the greatest impact if stakeholders have a clear-eyed assessment of their capabilities. We performed a single-blind test of nine methane-sensing satellites from three continents and five countries, including both commercial and government satellites. Over [...]
Global protection from tropical cyclones by coastal ecosystems - past, present, and under climate change
Published: 2023-06-27
Subjects: Environmental Sciences, Nature and Society Relations, Risk Analysis
Coastal ecosystems have the potential to contribute to disaster risk reduction and adaptation to climate change. While previous studies have estimated the value of current coastal ecosystems for reducing coastal risk, there have been relatively few studies that look at changes in ecosystem service provision, in the past and under climate change. We employ the probabilistic, event-based CLIMADA [...]
Subseasonal Variability of U.S. Coastal Sea Level from MJO and ENSO Teleconnection Interference
Published: 2023-06-27
Subjects: Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
Climate variability affects sea levels as certain climate modes can accelerate or decelerate the rising sea level trend, but subseasonal variability of coastal sea levels is under-explored. This study is the first to investigate how remote tropical forcing from the MJO and ENSO impact subseasonal U.S. coastal sea level variability. Here, composite analyses using tide gauge data from six coastal [...]
Geostationary satellite observations of extreme methane emissions from a natural gas pipeline
Published: 2023-06-27
Subjects: Physical Sciences and Mathematics
We demonstrate geostationary satellite monitoring of a large methane point source with the U.S. Geostationary Operational Environmental Satellite (GOES) constellation. GOES provides continuous 5–10-minute coverage of the Americas at 0.5–2 km nadir pixel resolution in 16 spectral bands. We use the shortwave infrared bands to track the full evolution of an extreme methane release from the El Encino [...]
Spatiotemporal Variation in Cave Percolation Waters: A Functional Approach
Published: 2023-06-27
Subjects: Hydrology, Longitudinal Data Analysis and Time Series
Understanding the mechanisms controlling spatial heterogeneity of drip water percolation into caves is essential for interpreting karst aquifer recharge and speleothem isotopic and geochemical records for paleoclimate analyses. Here we present the first analysis of drip rate variability using a novel time-varying Functional Principal Component Analysis (FPCA), validated against drip water stable [...]

Amidst nature's enchanting embrace, forests stand as revered guardians, safeguarding biodiversity and nurturing rural livelihoods. In this journey, a qualitative study takes flight, exploring the cherished perspectives of the community within Iligan City's rustic expanse in Iligan City, Philippines. Its purpose? To unveil the intricate dance between forest conservation efforts and local [...]
Notes on the Pens Collection of Australites in the Tate Museum, University of Adelaide
Published: 2023-06-26
Subjects: Earth Sciences, Other Planetary Sciences
The Tate Museum holds a large collection of (tektites) australites including the Pens Collection from the Florieton area in east-central South Australia. Many of these specimens are intact or near-so and have the various forms ascribed to their behaviour as they entered the Earth’s atmosphere. However, a significant number, some of which may have been initially fractured and broken by erosional [...]

Decoding the Dynamics of Climate Change Impact: Temporal Patterns of Surface Warming and Melting on the Nivlisen Ice Shelf, Dronning Maud Land, East Antarctica
Published: 2023-06-23
Subjects: Earth Sciences, Environmental Sciences
Surface melting in Antarctica can result in the formation of meltwater ponds and streams, which can encourage glacier basal sliding and ice flow; long-term severe surface melting can result in the formation of melt ponds and, eventually, supraglacial lakes (SGLs), raising the prospect of hydrofracturing. Measurements of these surface melting characteristics are useful for studying glacier and ice [...]

Food web complexity alters phytoplankton resistance and resilience to nutrient pulses in experimental ecosystems
Published: 2023-06-23
Subjects: Life Sciences
Food webs may mediate the resistance and resilience of ecosystems to disturbances driven by climate change. In aquatic ecosystems, greater food web complexity is theorized to increasing the resistance (longer response time) and resilience (shorter recovery time) of primary production to pulse disturbances, yet experimental evidence is limited. We simulated two storm-induced pulse disturbances by [...]
